Fiber to The x (FTTx)
Malaysia Installation Standard


Introduction


Overview FTTx


Malaysia is using single mode fiber with either 1310 nm or 1550 nm light signal
depend on the distance. These lights are infrared light thus cannot be seen
with naked eyes.

Fusion splicing process is used to
permanently join two fiber end


TM UniFi
All wireless adapter or device with standard
(IEE802.11b/g/n) will work fine with wireless
Residential Gateway (RG).

USB storage device can also be used as
share storage. This can be done by
connecting it to RG USB port .

For RG detail configuration settings refer this site http://netops.tm.com.my/netops2/misc/TMRND%20RG%20Installation%20Guide%20R1.2.pdf

Fiber Wall Socket (FWS)

provided by the developer with Standard Connector (SC)
output connector
 Provided by the developer in all premises
 Must be placed at 0.3m above the floor level and 0.3m
from the corner of the wall or from electrical points.
 made from the non-corrosive material or treated metallic
material to resist corrosion placed adjacent to the electrical
power socket.
 Recommend 2 AC power outlet min 1 near FWS
 1 SC/UPC (Standard Connector-Ultra Polish Connector)


• trunking must be used to lay the cable between the FTB, located at the outside wall, and the
FWS located inside the premise.
• trunking bending radius must greater than 10 times of the trunking size
• must be made from PVC or harder type of conduit with minimum 19mm diameter


• developer must provide manhole to the nearest NFP manhole before the NFP can lay their
cable.
• FTB to FWS total IL <1.5 (TM standard) , 1.52 (MCMC standard) dB


Pole Drop cable

Drop cable can be 1 or 2 core single mode fiber

• Drop Fibre generally must not exceed 50m

Underground Cable

• Drop Fibre must be connected to the premise wall FTB and at the other side it
must be coiled inside the manhole and must be covered with end cap or terminate
the fibre core inside the cable closure.
• Drop Fibre generally must not exceed 50m


• FTB to FWS = IL <2.1 (TM Standard), 2.3 (MCMC standard) dB


Manhole

• Cover shall be made from fiber or any light material type which should be possible to
be accessed by 1 person only
• recommended size is JRC7 or JB30
• be able to sustain up to 20 years


Underground duct-ways
• required to connect the road side manhole to the
Telecommunication Room (TR) inside the building or direct to
the building
• should be build to accommodate the local line for 20 years
period in future expectation
• material of the duct shall be PVC or harder and must be
strong enough to protect the cable inside
• duct diameter must be minimum of 50 mm
• The duct routes must be as straight without sharp bends and
not obstructed.
• The maximum allowable bending radius is 20 times of duct
diameter.
• shall ensure that the constructed ducting system has a
minimal risk from the nature disaster including flood
• duct sectional length (manhole centre to manhole centre
distance) of 180m to 220m


• This design is applicable if the depth of the drain is less than 450mm (1.5
feet)
• small pit with minimum size 300mm X 300 mm X 300mm shall be prepared
for easy access during the maintenance work


• depth of the drain is more than 450mm (1.5feet)
• the duct must be protected by minimum 100mm of GI pipe to cover the duct from
broken


• meet ITU G.657A


Other SDU


Other SDU example
Shop lot


Developer must provide a space minimum 600mm x 600mm beside FTB


Internal cable for building

Internal Fibre cable is used for corridor and indoor cabling

• Single-Mode and meets specification ITU-T G.657A


Multi Dwelling Unit (MDU)


MDU building
Cabling for MDU consist of 4 elements as below:
a. Campus backbone cabling
b. Building backbone-vertical cable
c. Building horizontal cable
d. Telecommunication outlet cabling.


• Number of effective core for each premise is two cores for business
building and one core for residential building.

• highly recommended to have minimum 30% spare cores for business and
10% of spare core for residential building.

•internal cabling must be tested and the result must be submitted to the
NFP during the cabling approval process.

•All the cable must be tested from point to point for every termination.

•All the internal cabling for MDU must have a code or naming convention
and tagged properly for easier maintenance and connection with NFP’s
cable. All tag must be stated clearly and sealed with transparent material for
easy to read.

•All cables need to be inventoried and one copy of inventory information
must be submitted to the NFP during the cabling approval process

•Main hole at the road side until duct way into the building shall be provided
by building owner


code or naming convention for the Internal Vertical Cable must follow standard
as shown :


Horizontal cable
horizontal cable is referred to the cabling between Floor Riser FTB to FWS inside each
individualunit premise

The internal horizontal cable must be covered
either
a. Through ducting
b. Concealed inside the wall
c. Concealed underground floor
c. using conduit through the ceiling


Network boundary 1 - Network Boundary between the NFP’s and the building
management
Network boundary 2 - Network Boundary between the building management and
the individual customers


Riser Specification


• campus backbone cable and Internal Vertical Cable are normally same
• Cable type must be loose tube or ribbon single mode fibres with features comply with
G.652D or G.657A specification


Internal Horizontal Cable typically follows the specifications defined
for distribution fibre and the type must single-mode fibre.


manhole, with minimum specification of JC9C size with 4 duct ways for
connection to the nearest NFP’s manhole


Cable trench


Telecommunication room
house the service provider equipment and cable


• shall be provided with electrical AC supply from the utility supplies at a nominal
of 415 V, 3 phase, 4 wires, 50 Hz system or at a nominal voltage of 240V AC Single-
Phase system with solidly earth system.

• shall be equipped with a 20A TPN metal clad Distribution Box (DB) of 20A
• shall be equipped with daylight type fluorescent lighting that can provide a minimum of
300 Lux luminance at floor level.
• FTB must be located at the right most position as this is the nearest point leading to the
internal riser NFP’s network elements will be located adjacent to the FTB


Insertion Loss (IL) FTB inside Telecommunication room, to FWS inside each
individual premise must not exceed 2.2 dB.
