FIXED NETWORK FACILITIES - IN-BUILDING AND EXTERNAL
(BROWNFIELD MULTI DWELLING UNIT)
0. Introduction
An access network is a type of communications network which connects subscribers to their immediate
service provider. Access network should also support Point-To-Point (P2P) technologies such as
Ethernet, which bypasses any outside plant splitter. The process of communicating with a network
begins with an access attempt, in which one or more users interact with a communications system to
enable initiation of user information transfer. An access attempt itself begins with an issuance of an
access request by an access originator.
This Technical Code is intended as a reference for architects, consulting engineers, owners, property
developers and others who are responsible for planning and erecting buildings. This is in line with the
objective to meet the requirements of end users for fixed communications services with minimum
disruptions to all services offered by the service providers.
1. Scope
This Technical Code specifies the requirements for Multi Dwelling Unit (MDU) infrastructure
development for existing building. The building is more than 5 stories which equipped with the
Subscriber Distribution Frame (SDF) or Telecommunication Room (TR).

be consider by using the OTRD measurement:
a) To obtain the accurate measurement, open end side shall be closed properly to avoid entering of
the light that may contribute to the false light reflection to the test environment.
b) To measure the first connector that connected to the test patch cord, a minimum of 10 m spool fibre
shall be used between OTDR and the test adaptor. However, to get a better result the longer spool
fibre, i.e. 100 m length is recommended to be used.
c) At the open-end side, another minimum of 10 m length of spool fibre also needs to be used to obtain
the accurate measurement of the last connector.
d) A high quality of test patch cord shall be used to get the accurate measurement.
OTDR can provide each event measurement in the tested network and should be used during
troubleshooting process. The sample test setup for OTDR measurement is as shown in Figure 41.
