Telephone Cables

 ADSL Connecting Cables

Application

The cables are designed for ADSL transmission system. The cables are characterized by guaranteed data speeds up to 10MHz. The cables have a small cable diameter with an easily removable sheath.

Standards

• IEC 61156-1 Part 1

• ANSI/ICEA S-80-576

Construction

Conductors
Solid annealed bare copper sized 0.4mm as per ASTM B-3/IEC 60228 Class 1

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 in concentric layer to form the cable core

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

Screen
An aluminium polyester foil is applied in close contact with tinned copper braid screen

Sheath
PVC or LSZH compound

Ripcord
Ripcord may be placed to facilitate sheath removal
