The cable is designed to handle low frequency signals and is intended to be terminated in Insulation Displacement Connectors (IDC), but may be soldered or wrapped. The cable is intended to take the place of Polyvinyl Chloride (PVC) sheathed cables and will withstand similar environments with a similar working life.
There are two modes of construction; Layer for general use and Units of 20 pairs which include a 1.38mm diameter insulated earth conductor, for use with customer distribution schemes.
Plain annealed solid copper wire; polyethylene insulated twisted pair,polyester tape, continuity wire, aluminised polyester screen, fire retardant tape, LSZH sheath.
N.B. In the event of fire, the gases evolved from this cable are free from Halogen and the design is optimised to limit the quantity and cleanliness of the smoke evolved during this period. Although the acronym LSZH is applied to the sheath material, the terms LSOH, ZHLS and HFFR are also applicable.
