FTTH CUSTOMER PREMISES DUCTING AND FIBRE WIRING

S No Test case Reference Remarks

1 Check of Approved layout

diagram & documentation

Hard/Soft Copies to be checked

2 OF cable Termination.

OF cable to be terminated on FTB as per EI No.-

EI/ACCESS NETWORK/11-12/13(House wiring of

FTTH) and P.O.

OF cable should be neatly laced and labeling to be

done.

3 Termination of OF cable on

splitter

Drop fibers from FTB are to be laid with suitable

protection and termination on splitter as per EI No.-

EI/ACCESS NETWORK/11-12/13 (House wiring of

FTTH) and P.O.

4 Cabling from splitter to

ONT Location

Drop fibre can be layed to ONT location through

micro duct/PVC pipe with suitable clampings as per

EI No.- EI/ACCESS NETWORK/11-12/13 (House

wiring of FTTH) and P.O.

5 Trench depth

Sample pits to be taken and trenching depth should

be as per EI No.- D-001 Issue IV dated 31.01.2007

(Laying practices of Optical fibre cable)

6 Optical link budget

RX sensitivity > -28 dbm at ONT Location

Power Loss calculated is as below

(Length in KM X 0.34 db/KM)+(0.15 db X no of

connectors)+ (0.1 db X no of splices) + (3 db

margin of error). Splitter losses to be added.

7 ONT installation

ONT, UPS to be wall mounted near A/C supply

point as per EI No.-EI/ACCESS NETWORK/11-

12/13(House wiring of FTTH) and P.O.

Hardware/software conformity of installed

equipment to be verified as per BOM.

8 Connectivity details and IP

details.

OLT to ONT path connectivity details.

9 Check of services Check services HSI, VOIP, IPTV, RF Overlay as per

the tariff plan.

10 Interruption Test

Physically isolated fibre at splitter/ONT and

reconnect.

System should start-up without any intervention.

11 Session stability Session stability to be carried out for 2 hrs.

12 Verification of data speed

for Triple Play Services

FTTH is capable of data speed for downstream up to

2.4 Gbps and upstream up to 1.2 Gbps




Dated 12.03.2012

13 Check for splitter

specifications

Annexure-I EI No.-EI/ACCESS NETWORK/11-12/13(House

wiring of FTTH) and P.O.

14 Check of bending of Optical

cable

To avoid loss.
