scope:

This standard specifies the:

a) parameters to promote consistent optical fibre cabling infrastructure throughout Network Rail's optical fibre network; and

b) permissible optical loss and configuration of the network that will extend and preserve the network's reliability, availability and maintainability.

The design principles and parameters set out in this standard apply to all designs that grow, change, or repair Network Rail's optical fibre infrastructure. This includes optical fibre infrastructure supporting Signalling circuits and Electrical Plant applications.

This standard applies to people responsible for designing additions to or modification of Network Rail's optical fibre infrastructure.

This standard does not apply to intra-building optical fibre infrastructure with no operational traffic.

Purpose

The purpose of this standard is to set out the principles and considerations to be taken into account for additions to, or modifications of, Network Rail's optical fibre infrastructure. The objective of this is to maximise its potential capacity and apply a consistent approach that will perpetuate reliability, availability and maintainability of the network.

Compliance with these requirements will optimise the architecture and maximise the performance of Network Rail's optical fibre infrastructure and control the risk of its failure to support railway applications
