1 Purpose The purpose of this document is to specify the technical requirements for Single Mode Optical Fibre (SMOF) cable, hereafter referred to as “the Cable”.

The Cable is required for carriage of telecommunications services by way of optical transmissions over distances ranging from a few metres to over 100 kilometres. The cable is to be suitable for operation in the general rail environment including areas electrified with 1500V DC or High Voltage AC and locations where fire and life safety are an issue.

2 Scope & Application The scope of this document includes SMOF Cable with construction suited to the following installations:

• General Installation - Cable suitable for general installation in the rail environment by way of direct burial, hauling into underground ducts, hauling into above ground steel troughing and laying in ground level concrete troughing.

• Fire Safe - Cable for installation in underground stations or other underground facilities and tunnels where fire and safety are a primary concern.

• Blown Cable - Cable for installation by way of air/gas blowing through continuous conduits.

The scope of this specification does not include the following optical fibre cables:

• Multi Mode Optical Fibre

• Aerial Cable - (Aerial SMOF may be included in a later revision of this specification or a separate specification in future.)

• Fire Resistant - (Fire Resistant SMOF may be included in a later revision of this specification or a separate specification in future.)

• Internal use building horizontal and riser cable

• Pre-terminated SMOF tie cables - (These are the subject of a separate specification).

This specification is applicable to both procurement and type approval assessment of the Cable
