Telecommunication Cable

Description

dc deepcab paired cable products are manufactured in a variety of gage sizes, dimensions, insulation materials, shielding configurations to meet the technical requirments of many different types of systems. Paired cables allow balanced signal transmission,wich results in lower crosstalk through common mode rejection. Due to the improved noise immunity of twisted pair, they generally permit higher data speeds than multi-conductor cables.
 

Telecommunication Cable Make-up:

 
Annealed tinned Solid copper wire ( according to IEC - 60228 ), Hard PVC - based core insulation (Mini. Insu. Resistance 5000 mega ohms/Km), every two cores twisted in pairs, pairs twisted in layers with varying layers to minimise crsootalk, overall myler tape wrapping, outer sheath of PVC compound flame-retardent normally grey. Specification as per ITD 113C & 114B and meet to customer specific requirment.
