Introduction
We are pleased to issue the updated
Telecommunications Infrastructure
Standards for Buildings v.5.
The new design guidelines in this
document are based on our prior
experience of offering quality
telecommunications services to our
consumer and enterprise customers
across UAE.
The purpose of this document is to:
• Introduce the new design
guidelines for fibre infrastructure
to enable property developers,
consultants, and contractor
to deliver high-quality, futureproof telecommunications and
multimedia services to their
tenants.
• Provide a guide for consultants,
contractors, and engineers related
to the ‘No Objection Certificate’
(Building NOC) process that
includes design and construction
drawing review and Structure
Cabling Material data sheets
review, with samples checking and
site inspections required during
implementation.
• Meet the growing demand for
improved communications at work,
at home, in business, and in public
services.
Developers are encouraged to engage
with us in the early stages so that any
process and/or design issues may be
resolved.

General
specifications
A number of telecom rooms will be
required in a building depending on its
characteristics. The following room types
are required and the details of these
rooms shown below:
• Main telecom room
• Mobile service room
• Rooftop mobile service room
• Floor telecom closet
In multi-storey buildings the telecom rooms
should be vertically aligned and linked
by a shared containment system. This
containment system must not reduce the
minimum requested space. All telecom
rooms must be dedicated for the use of
du. The rooms must be easily accessible to
du personnel 24 hours a day and secured
from unauthorised entry.
Telecom rooms must not be in close
proximity to any sources of the following:
• Heat
• Moisture
• Corrosive atmospheric or
environmental conditions
The rooms should be clean and free
from any items not directly related to the
specifications in this document such as:
• Non-du equipment
• Utility pipes
• Sprinkler systems
• Windows
All telecom spaces and pathways must
be pest controlled using best available
practices. It should be noted that rodents
often gnaw cables resulting in damage
and the potential for service disruption.
Hence, special attention should be given to
preventing rodents from entering telecom
spaces and pathways. This could involve
the installation of covers to cable trays;
if this is the case these covers must be
removable to allow for the installation of
additional cables.
The walls, floor and ceiling should be
painted and treated with anti-dust and antistatic coating to minimise dust and static
electricity. Walls and ceilings shall receive
primer and finish coat of light colour paint.
In order to move equipment into and out
of telecom rooms, all entrances must not
be smaller than 900mm x 2100mm (WxH).
All telecom rooms must comply with
municipality and national authority
standards and regulations, such as
those issued by civil defence and utility
companies. Notwithstanding this, it
is expected that the following will be
provided:
• A
ll telecom spaces should be fitted
with smoke detectors connected to
the building management system.
• A
ll telecom spaces should be fitted
with emergency lighting.
• All containment openings to telecom
spaces must be sealed with a
regulation fire retardant material.
• All doors to telecom rooms must
be of solid wood core or steel
construction, fire retardant with a
minimum rating of 2 hours.
• All doors to telecom rooms must be
outward opening with an automatic
door closer system fitted on the
hinged edge.
• All doors to telecom rooms must
be labelled.
• The room must be free from
contaminants and pollutants.
• High voltages
• Radio frequency interference (RFI)
• A
ll telecom rooms should have basic
firefighting provision of handheld CO2
cylinder type extinguishers.
• Electro-magnetic interference (EMI)
The rooms must not be directly beneath
or next to wet areas such as:
• If the building developer has any
concerns over safety, especially fire
protection and suppression systems,
this should be raised with du at the
NOC stage.
• Showers
• Washrooms
• Swimming pools
• Garbage area

Safety and other
considerations
// Building Infrastructure Guideline v.5
// Building Infrastructure Guideline v.5
Temperature
and humidity
All telecom rooms must be maintained
at 20°C ± 3°C and the relative humidity
at 50% ± 10%. However, floor telecom
closets can be maintained within 20°C to
30°C temperature range.
The Main Telecom
Room (MTR)
A main telecom room must be provided
on the ground floor for all multi-storey
buildings. This room will be used for the
termination of telecom fibre optic cables
and to house telecom equipment, if
needed, now or in the future.
Generally, the MTR can be shared by both
du Fixed and Mobile services. If a mobile
service room is required in the building
(more than G+10) the first mobile service
landing room can be shared with the MTR.
The minimum combined room dimension
should be 4m x 4m x 3m (WxDxH) and
maybe increased depending on the
functions and features of the building.
The room specifications are detailed
in Appendix_1_Figure 5 to 9. If the
architectural design limits the room
sharing, then two dedicated rooms with
minimum sizes of 3m x 3m x 3m (WXDXH)
each must be provided.
The room specifications are detailed in
Table-1, Table-2, and Appendix_1_Figure-1
to 3 and 18.
Refer to Appendix_1_Figure-14 to 16
for Rack elevation layouts details.
9
The 3m clearance height specified is the
minimum finished clearance after taking
into account allowances for raised floors
(if used), overhead cable trays and any
other obstructions such as lighting fixtures
and beams. In areas where overhead
trays are used, a minimum headroom
access of 300mm is required above the
tray. Depending on the telecom room
usage, a ‘raised floor’ might be required
inside the MTR having active equipment,
particularly commercial or mixed use
buildings. A minimum of 300mm height
above the base floor of the room should
be provided. Tile cutting details are
specified in Appendix_1_Figure-25. In other
cases involving residential buildings, raised
floor is not mandatory, and will be further
advised during the NOC stage.
The floor level of the room must be
constructed at the same level as the
outside access or corridor. If this cannot
be met, then a suitable ramped entry with
an anti-slip surface must be provided. A
threshold step of 100mm must also be
provided inside the room under the raised
floor to prevent any ingress of water from
outside the room.
The door of the main telecom room
must have outward opening with size not
smaller than 900mm x 2100mm (WxH).
The door should be labelled ‘Main Telecom
Room’ “‫الغرفة الرئيسية لالتصاالت‬
All cables in the main telecom room
must be properly routed to the desired
destinations. For this purpose, an
adequately sized cable tray system must
be installed to maintain the connectivity as
described in Appendix_1_Figure-20 to 21.
Clustered buildings
Group of towers
If a project consists of a cluster of multitenant buildings, then all the requirements
of a single tower still applies. One of the
buildings will be selected as the location
for the main telecom room, which usually
stands in the centre of the cluster or often
times closest to the main telecom duct
entry points. This would require the cluster
of buildings to be linked to the designated
main telecom room via multicore single
mode fibre cables. The details of this
arrangement should be discussed with du
during the NOC stage. Cabling concept
is described in the clustered building
schematic diagram in Appendix_1_
Figure-22.
The Mobile
Service Room
(more than G+10)
As mentioned in the MTR section, du Fixed
and Mobile Services can be combined in
one room. The first mobile service room
can be shared with the MTR to serve the
first 10 floors of the building. If sharing
is not feasible, a dedicated 3m x3m x 3m
(WXDXH) mobile service room can also
be provided. Accordingly, the mobile
service rooms must be provided for every
10 floors thereafter. The locations of the
mobile service rooms must be close to the
floor telecom closet (FTC).
The mobile service rooms must have a
minimum distributed floor load rating of
10 kN/m2. The door dimension must be
900mm x 2100mm (WxH) and opening
outwards.
The doors should be labelled ‘Mobile
Service Room’ ‫غرفة خدمات الهاتف المتحرك‬.
Refer to the Table-2 and Appendix_1_
Figure-10.

// Building Infrastructure Guideline v.5
Floor Telecom
Closet (FTC)
A floor telecom closet must be provided
on each floor of all multi-storey buildings.
The floor telecom closet is required to
provide a flexible point for the installation,
pulling and maintenance of telecom cables.
FTC must have a minimum dimension of
2m x 1m x 3m (WXDXH).
The floor telecom closet should be
provided with two outward opening doors
with a minimum total opening of 1500mm
x 2100mm (WxH). The door should be
labelled (Floor Telecom Closet ‫حجرة خدمات‬
‫) االتصاالت الطابقية‬
In the case of a multi-storey villas,
townhouses, G+1 warehouses or small
retail shops, floor distribution boxes will
be required with a minimum size of
300mm x 300mm x 150 mm (WxHxD), as
an alternative to replace FTC.
In high rise buildings which usually
exceed 30 floors, proper planning and
consideration must be given to the FTC
space and dimension, which might be
increased. It is highly advisable to seek du
advice and pay close attention during NOC
stage to understand the concept of high
rise building infrastructure design. Refer to
Table 3 and 4 and Appendix_1_Figure-4
for the complete detailed layouts of FTC.
Rooftop mobile
service room
(up to G+10)
Rooftop mobile service rooms must be
provided on the roof of all multi-tenant
buildings up to G+10 and access must be
provided to the building riser system.
The door dimension must be 900mm x
2100mm (WxH) and opening outwards and
should be labelled ‘Roof Telecom Room’
‫غرفة خدمات الهاتف المتحرك على السطح‬.
// Building Infrastructure Guideline v.5
The rooftop mobile room must have a
minimum distributed floor load rating
of 10 kN/m2.
An opening must be provided with a
dimension of 600mm x 400mm (WxH),
500mm below the room ceiling in walls
facing the building’s rooftop area.
Space must be reserved on the rooftop of
the building for the installation of mobile
service antennas. This will vary from
building to building, but will typically be
at the corners of the building or on any
raised structure on the rooftop. The exact
details will be defined during the NOC
stage. Refer to Appendix _1_Figure-10 for
the complete detailed room layouts for
mobile service rooms.

16
Vertical
Containment
Horizontal
Containment
Multi-storey/multi-tenant buildings
Multi-storey/multi-tenant buildings
Risers must be provided in multi-storey/
multi-tenant buildings to allow the
installation of telecom cables from the
main telecom room to the floor telecom
closets, mobile service rooms and rooftop
mobile service rooms. Hot-Dip Galvanized
(HDG) slotted steel cable trays must be
provided in the risers to carry the telecom
cables between all the telecom rooms. It
is recommended that the main telecom
room and floor telecom closets should be
designed so that they are vertically aligned
within the building.
The horizontal containment for routing
cables from the floor telecom closets to
consolidation points on the served floor
can use a number of systems (cable trays,
conduits, etc.). The solution will depend on
the characteristics of the building. Conduits
must only be used when the consolidation
point locations are permanent, the cable
density is low and the flexibility to modify
the routing is not required. Specification
for the size of this containment is given in
Appendix_1_Figure-20 to 21
Two cable trays, with the following
minimum dimensions are recommended:
• One of 500mm x 100mm (WxH) with
Heavy Duty Return Flange (HDRF) for
fibre optic cables.
• One of 300mm x 50mm (WxH) with
Heavy Duty Return Flange (HDRF) for
GSM cables (covering all floors from
last basement till roof).
If it is not possible to provide all of
the cable trays running vertically then
horizontal trays of the same size should be
provided.
Note: above cable trays requirements to
be finalised during NOC stage.
Within homes
In case of multi-floor apartments/villas, the
UTP cables between the floors must run
through 50mm diameter PVC conduits
via junction/pull boxes located on each
floor. The junction/pull boxes must have a
minimum dimension of 300mm x 300mm
x 150mm (WxHxD). The slab opening
for these conduits must be in a suitable
and accessible location in every floor. It
is recommended that all vertical conduit
runs be aligned to ease the installation of
cables.
// Building Infrastructure Guideline v.5
Note: Intermediate PVC junction/pull boxes
with minimum size of 300mm x 300mm
x 150mm (HxWxD) must be provided on
individual runs that exceed 30m. PVC
junction/pull boxes must also be provided
where an individual conduit run has a
sharp change in direction.
The cable tray minimum dimensions are
described below:

Duty Return Flange (HDRF)
For office/commercial buildings, the
horizontal containments should be
extended till inside the entrance of each
office units.
Within homes
All UTP cables inside the home must run
through PVC conduit with a minimum
25mm diameter from the home
consolidation point to each dual outlet.
If more than one dual outlet is fed by
a conduit then the size and quantity of
the conduit may need to be increased.
Intermediate PVC junction/pull boxes must
be provided on individual runs that exceed
30m. PVC junction /pull boxes must also
be provided where an individual conduit
run has a sharp change in direction.
Cluster of buildings – groups of towers
Where a building consists of a group of
towers (on a common shared podium) all
of the requirements of a single tower still
apply. In addition, cable trays must be
provided linking the main telecom rooms of
all towers, exact requirement to be finalised
during NOC stage.
One cable tray with the following
dimension must be provided:
• 300 x 100 (WxH) with Heavy Duty
Return Flanged (HDRF)
These trays should be readily accessible
in common areas to facilitate any future
provision of additional cables. However,
if these trays are in an area accessible to
the public and are less than 4.8m above
the floor then the trays should be covered.
For more details, refer to Appendix_1_

Cables
General
specifications
Specifications of all the cables to be used
must be submitted to du for approval
during the NOC stage. This must also
include test reports showing that the
performance of the cabling system meets
defined requirements. Cable test must be
performed using power metre and OTDR
tests, whichever is applicable. Details for
cable labelling are included in Appendix_2
Fibre Optic Cables
The quantity of fibre optic cables that
must be provided and installed from the

2 core (individual pair) fibre optic cables
will be required from MTR up to each
apartment, retail shop, and pre-defined
office. It is recommended to apply direct
fibre installation up to G+30 only to
maintain cable management inside the
FTC and MTR.
The fibre cables must be provided
from the main telecom room to each
consolidation point and should be of
continuous lengths free from joints,
branches or patching. By default, all the
fibre cables should pass through the FTC.
The fibre cables should be labelled at
both ends with a unique reference for the
consolidation point served and the room or
area of origin. Labelling details are included
in Appendix_2
All fibre optic cables should be terminated
inside the MTR and inside the unit CP
cabinet. Refer to Appendix_1_figure-19

Fibre optic cable requirements –
from MTR to FTC (multicore fibre)
Fibre optic cables – from MTR to rooftop
mobile service room
For high rise buildings exceeding G+30, a
FTC must be selected for every 10 floors.
Multicore fibre cable must be installed
in a mini ODF inside the FTC, where the
number of fibre core will depend on the
number of units in each served floor. 2
fibre cores per unit should be considered
as the basic foundation of multicore fibre
calculation.
12 single mode fibre pair cables must be
provided from the main telecom room to
the rooftop mobile service rooms. 10m of
spare fibre must be left neatly coiled.
If there are unused fibre cores, these must
be left un-terminated and coiled properly
inside the mini ODF and the MTR ODF.
Refer to Appendix_1_figure-26
Fibre optic cable requirements –
from MTR to FTC (shell and core)
For shell and core office development,
one pair of fibre optic cable per 200sq
m of leasable commercial area should be
provided up to FTC of the same floor.
Depending on the building design and built
up area, multicore fibre cables from 12
cores up to 288 cores may be required to
be installed between the MTR and FTC to
meet the cable quantity requirement.
The fibre cables should be labelled at both
ends with a unique reference for the floor
served and the MTR. Labelling details are
included in Appendix_2
All fibre optic cables should be terminated
inside the MTR and in the FTC mini ODF
cabinet. Refer to the FTC layout as shown
in Appendix_1_Figure-4
Fibre optic cables – from MTR to all
mobile service rooms
12 single mode fibre pair cables must be
provided from the main telecom room
cascaded to all mobile service rooms
ending at the last mobile service room.
10m of spare fibre must be left neatly
coiled.

CAT6 Copper
Cables
CAT 6 Copper cables – from
consolidation points to tenant outlets
To deliver services from the consolidation
points to the building outlets, unshielded
twisted pair (UTP) copper cables must
be provided. The complete design of
this service is the responsibility of the
building developer. However, the following
minimum requirements must be followed
for the efficient and effective provision of
services:
• The cables must conform to a minimum
of CAT 6 specification (Category 6, 100
Ohm, 4 pair 23 AWG as specified in
ANSI/TIA/EIA 568-B.2 Addendum 1).
• The wiring must be in a‘star’topology
fanning out from the consolidation
point.
• At the consolidation point the cables
should be terminated on an RJ45 patch
panel and labelled with the socket and
outlet served.
• In each outlet the cable must be
terminated to maintain the twists in
each pair up to within 5mm of the
termination.
• Proper strain relief should be provided
at the terminated ends of the cable.
• T
he components of the CAT 6 system
must be from the same supplier or at
least compatible to insure maximum
performance.
• D
esign should incorporate built-in
flexibility to meet the growing needs
of the occupants.
Administration and
labelling scheme
All the infrastructure components described
in this document must be clearly and
uniquely labelled. The label information
must correspond with the description on
the as-built drawings.
The type of label must be suitable for the
object being labelled and its environment.
This is particularly important for cables and
consolidation cabinets where a high quality
printed self-laminating type must be used.
For detail of the Labelling scheme refer to
the Appendix_2
• The CAT 6 cabling system must be
tested using an appropriate field test
instrument for compliance with ANSI
TIA/EIA 568-B.2 Category 6 (or
equivalent if a higher specification has
been used)
• Numbering and colouring of the pairs
should be as defined in EIA/TIA 568B,
SO 11801/EN50173 using the T568B
option.
• Dual RJ45 outlets with spring load
sliding shutters must be provided
wherever service is required (all outlets
should comply with the performance
specifications as detailed in ANSI/TIA
EIA 568-B.2 Addendum 6).
• E
ach socket in the dual RJ45 outlet
must
be wired back to the consolidation point.
• O
utlets must not be cascaded or looped
& there must be no splitting of cable
pairs.
• T
he maximum cable length from
consolidation point to outlet must
not exceed 90m.

Bulk service
requirements
Bulk service
application
This kind of service solution usually applies
to buildings that are having their own IT
network and system operator, such as
hotels, hospitals, schools, universities,
banks, airports, warehouses, workshops
and other similar establishments. Sharing
the client server or IT room with du can be
one solution to deliver the services simply
and quickly which is convenient for both
du and the client. In such cases of room
sharing, free space inside the client room
needs to be provided and reserved for du
usage. Free space could be either rack unit
space in an existing client rack or a floor
space inside the room to accommodate
a floor mounted rack dedicated for du.
A letter from the client should be
submitted during the building NOC stage
confirming the bulk service request with
detailed information on the required
telecom services.
22
// Building Infrastructure Guideline v.5
// Building Infrastructure Guideline v.5
The consultant is advised to approach du
prior to the Building NOC submission to be
able to assess and decide if sharing the
space with the client is the best approach
or a dedicated du room is technically
recommended for some reason or another.
If a dedicated room is required by du, the
room specifications as mentioned in the
telecom spaces section must be followed.
The final du requirements including space,
containment, cabling and power will be
finalised during the NOC stage.
Cable connectivity between du and the
client rack or room must conform to the
cabling standard of du, as discussed in the
cable section of this document. Single
mode fibre, UTP CAT6 and multi pair
CAT3 copper cables are generally required,
to be supplied, terminated and tested.
Final cabling connectivity design including
cable type and quantity will be advised
during the NOC stage. Refer to the
Appendix_1_Figure-17
23
Other special
requirements
Public phones, ATM machines and retail
kiosks
Provision needs to be made for the
connection of public phones, ATM
machines and retail kiosks. This must use
the same design as that prescribed for
commercial buildings; 2-core single mode
fibre (individual pair) from the main telecom
room to a business consolidation cabinet
must be installed. The final requirement
will be finalised during the NOC stage. The
business consolidation cabinet must be in
a secured location. It is the responsibility
of the building developer/consultant to
coordinate with du at the NOC stage for
any special or non-standard requirement.
Entry ducts
The building developer must provide leadin ducts from the main telecom room to
the plot boundary. The exact connection
points at the plot boundary will depend on
whether the du network already reaches
the plot.
Option 1 – du duct network already exists
• The building developer will be
responsible to connect to the du
ducting system.
• The operator will identify the location
and quantity of their lead-in ducts.
Option 2 – du duct network is still to be
built
• The building developer will be
responsible to extend the lead-in duct
to 1m outside the plot boundary.
• The building developer is responsible
for locating and clearly identifying lead
in ducts.
24
In both cases the building developer will be
responsible for the maintenance and repair
of lead-in ducts. The lead-in ducts systems
in this document are designed to meet du
requirements to serve the development,
building or property and must be used for
telecommunication purposes. The quantity
and size of these ducts for different kind of
developments is detailed in Table-6. Refer
to the Appendix_1_Figure-23 to 24
The lead-in duct specifications are as
follows:
• Made from black uPVC.
• Upmost part of ducts must be buried
to a depth of 600mm below finished
ground level.
• Clearly marked above ground level for
easy location.
• Sloping away from the building.
• Protected by concrete when running
under permanent paved surfaces.
• Sealed at each end to prevent the
ingress of any materials such as water,
sub-soil, gas, and pests.
• An entry/pull box must be installed for
any right-angled or sharp bends in the
lead-in duct route.
• If required at the entry to the main
telecom room, a wide-angle long radius
bend (factory made) may be provided;
alternatively an entry box may also be
provided.
• All ducts must include a draw rope
made of twisted mildew and rot
resistant polypropylene; minimum
outside diameter of 6mm; minimum
tensile strength of 2400lbs/1000kg/
In case of combined plots, two entry
locations are still required for primary and
secondary network connections; this will be
advised by du at the design stage.
// Building Infrastructure Guideline v.5
Lead-In ducts – villa complex
In the case of a villa complex, the building
developer must connect the lead-in ducts
to each villa in the complex. The lead-in
duct size must not be reduced until the
branching point for an individual villa.
Lead-In ducts – group of buildings
In cases where the building developer
wishes to share lead-in ducts between
a group of buildings (not on a common
shared podium), then the design needs
must be discussed with du at the design
stage.
Lead-In ducts - building entry
Where lead-in ducts cannot be routed
directly into the main telecom room, HotDip Galvanized (HDG) slotted steel cable
trays must be provided as an alternative.
These trays must be easily accessible
in common areas to facilitate any future
provision of additional cables. However, if
these trays are in an area accessible to the
public and are less that 4.8m above the
floor then the trays must be covered.
Entry boxes must be included wherever
the duct system has right-angles or sharp
bends or other factors to facilitate cable
pulling.
The following specifications must be
followed:
• Constructed with reinforced concrete.
• Fitted with a ductile iron frame and
cover.
• Minimum load rating 400kN.
• Cover to be marked ‘du – Telecom’.
• An earth rod must be provided with a
resistance of less than 5 ohms.
Note: A more detailed set of entry box
specifications and drawings are included
in Table-6
Please contact noc.request@du.ae
for any OSP design queries.
A cable tray of minimum dimensions
300mm x 100mm (WxH) with Heavy Duty
Return Flange (HDRF) will be required for
each plot entry point.
Lead-In ducts – entry box
Entry boxes are required to install
telecom cables through the lead-in duct.
The type and size of entry/pull boxes
will depend on the characteristics of the
building development. The details for entry
boxes are included in the text below and
summarised in Table-6. The quantity and
location of the entry boxes will depend on
the route from the main telecom room to
the network.
