The required number of tubes plus dummy fillers are assembled with water blocking filling helically around a non-metallic central strength member, the specification requires that the cable is neutrally balanced along its central axis.

The specification requires the fibre assembly to be covered with a high electrical grade, anti-tracking, Black HDPE sheath. Ripcords are inserted under the sheath to aid stripping and terminating of the cable. The cable sheath is specified as having two equally spaced, axial yellow stripes, to identify it

The single mode fibres specified to manufacture these cables meet the requirements of Category 2 fibres as defined in BT Specification CW 1505. The transmission application for these cables are for systems operating in the wavelength range of 1260nm to 1625nm

No metallic materials are used in the construction of these cables.

The cable meets the Operational Requirements specified in BT Specification CW1500-11.

All of the polymeric materials specified in the construction of these cables meet the requirements of BT Specification CW1500-7
