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
