Telephone Cables

 XDSL Connecting Cables

Application

The cables are designed for XDSL transmission system. The cables are characterized by guaranteed data speeds up to 40MHz.

Standards

• ER.f5.113

Construction

Conductors
Solid annealed bare copper sized 0.5mm as per ASTM B-3/IEC 60228 Class1

Insulation
Solid polyethylene as per ASTM D 1248/IEC 60708

Twisted Pairs
Insulated conductors are twisted into pairs with varying lays to minimize crosstalk

Cable Core Assembly
The pairs are cabled together in layers of 12, 13 & 25 pair unit to form the cable core. Units are identified by colour coded binders.

Core Wrapping
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap

Screen
An aluminium polyster foil is applied longitudinally with an overlap

Sheath
Black low density polyethylene as per BS 6234/IEC 60708

Ripcord
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
