Aanvraag

The cables are used as basic access for ISDN services in central office wiring and cabling for ISDN basic access installation.

Normen

 

• ER.f5.058

Bouw

Dirigenten
Solid annealed bare copper sized 0.5/0.6mm as per ASTM B-3/IEC 60228 class 1

Isolatie
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

Condooms
PVC/LSZH

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