Work Instruction for Jointing, Terminating and Testing Optical Fibre Cables
|Publication Date:||4 March 2017|
This Network Rail standard specifies the:
a) principles and practices for jointing and terminating optical fibre cables; and
b) optical fibre test methods and values of permissible optical loss.
The requirements of this standard only apply to cables containing optical fibres generally to ITU-T Recommendations G.652 and G.657.
The requirements of this standard and NR/L1/TEL/30092, NR/L2/TEL/30098, NR/L2/MTC/088 and NR/L3/MTC/089 apply to projects involving jointing, terminating or testing optical fibre cables on Network Rail Controlled Infrastructure.
This standard applies to people undertaking jointing, terminating and acceptance testing of optical fibre cables on Network Rail Controlled Infrastructure.
This standard sets out the specific requirements and parameters for jointing, terminating and site acceptance testing of optical fibre cables that comprise, or connect to, Network Rail's optical fibre infrastructure.
Compliance with these requirements will maximise the performance of Network Rail's optical fibre infrastructure and control the risk of its failure to support railway applications.
