ADSL Connecting Cables |
|
| |
| Applications |
|
| |
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. |
