STRUCTURED CABLING
Structured cabling overview
IS Structured Cabling
IS structured cabling solutions allow physical copper or fibre connections in our Data Centres
between Carriers and co-location customers. The services are designed for minimum touch
maximum deployment. Should customers request, diverse routes can be offer ed to ensure
additional resilliance in the data centre.
How does it work?
IS uses its world class structured cabling teams to pull fibre or copper between points in our Data
Centre. We adhere to BICSI (Building Industry Consulting Service International) standards and
the ITIL (IT Infrastructure Library) framework. We guarantee zero impact on existing customers
infrastructure. Our dedicated teams use our integrated Change Management System (CMS) to
ensure compliance in our Data Centres. Our patch managemen t and schedules give you the
peace of mind that we can easily trace and fix any faults that may occur on your dedicated
structured cabling.
Solution options
“INX Cross-Connect” – Any link into either Jinx or Cinx
Cabling from MMR to the INX Hosting envir onments will be the sole responsibility of
Internet Solutions and is referred to as the “INX Cross -Connect” this will be charged at a
once off amount as stipulated by ISPA. Cabling still needs to be run into the IS MMR
which will be charged at a monthly fee described in the pricing table.
ECNS / I-ECNS License Holder– MMR – ECNS / I-ECNS License Holder
Any cabling run from a ECNS / I-ECNS License holder would need to first terminate in an
IS MMR and from there be run to the required destination, this servi ce would attract a
once off setup charge as well as a monthly service fee as described in the pricing table.
IS Client – MMR – IS Client
Any cabling run from one IS Client to another would need to first terminate in an IS MMR
and from there be run to the the separate IS Client, this service would attract a once off
setup charge as well as a monthly service fee as described in the pricing table.
ECNS / I-ECNS License Holder – MMR – IS Client
Any cabling run from an ECNS / I-ECNS license holder to an IS client in the IS Data
Centre would need to first terminate in an IS MMR and from there be run to the IS client,
this service would attract a once off setup charge as well as a monthly service fee.

Cabling Options
Twisted Pair Cables
Twisted pair data cables are designed to TIA/EIA 568 C.2
standards of performance for the horizontal segment of the
network. Only Category 6 copper cables, which support
gigabit Ethernet, are available for installation. In the real
world, a cable with higher bandwidth will support it better.
Network transmission depends on a signal with as little
noise as possible; a noisy signal increases bit -error thus causing retransmission and
slowing the throughput of the link. High bandwidth cables have less noise as expressed
by the higher ACR value. W hen choosing a twisted pair cable, consider higher bandwidth
cables for longer or higher speed links.
Copper Patch panels
Patch panels are strips of 24 or 48 outlet ports built to fit in a
standard 48 cm (19 inch) rack. The ports may be subdivided
into groups of 6.
Fibre Optic Cable
Distribution cables are a compact solution for transporting up
to 144 tight buffered fibers (bundled in 2-48 fiber subunits)
over a long distance. Aramid yarn provides tensile strength
while a dielectric strength member gives support for pulling
and for long riser installations. Distribution cables are more
rugged than cordage due to the harsher installation
environment. Because tight buffered fiber is easier to handle and requires less
preparation than loose tube buffered fiber, distribution cables can be installed more
quickly and economically. Distribution cables start as single unit cables in constructions
of up to 24 fibers. Cables with more than 24 fibers are composed of multiple single cable
subunits. The multiunit construction permits easy placement and tracing of single-mode
and multimode fibers in the same cable (called a composite cable). These composite
cables help a network prepare for future growth.
Fiber Optic Connectors
While many fiber optic connectors have been developed, three main types are presently
in use - the SC and LC. These connectors are designed to fit onto 900 μm tight buffered
fiber, loose tube cable with fan-out kits, or 1.6 or 2.9 mm cordage. Ceramic ferrules are
customarily used to position the fiber. A fiber connectorized at one end is called a pigtail;
if connectorized at both ends, it ’s called a patchcord. Pre-terminated patch cords and
pigtails are readily available (Fibre pigtails are included)

LC connectors
LC connectors are Small Form Factor (SFF) connectors about
half the size of SC/ST connectors. They come in both simplex and
duplex versions. They can be easily snapped in and out and offer
excellent optical performance in a very small size. Most LC
connectors have a ceramic ferrule. TIA/EIA 568 allows for the use
of SFF connectors such as the LC. The LC connector is
increasingly popular in enterprise networks and is often the connector used in network
switches.
SC connectors
SC connectors are a push/pull design abo ut the same size as
an ST. They are sturdy, easy to handle, pull-proof when used
in cordage and can be yoked together into a convenient
duplex assembly. The SC connector has a long heritage of
successful deployments around the world. They offer excellent
optical performance and are recommended by TIA/EIA 568 to illustrate fiber systems.
Most SC connectors have a ceramic ferrule.
Fiber enclosures
Fiber enclosures may act as the intermediate cross/interconnect
and may be wall or rack mounted (panel pre-installation is
optional). Incoming fiber may be directly terminated with a
connector or be spliced to pigtails within the enclosure and
protected within an internal splice holder. Capacities vary
depending on whether simplex or duplex connectors are b eing
used and if connectorized fibers are being combined with spliced fibers.
