    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
