This cable is used for interconnecting between frames of PCM equipments with 120W characteristic impedance.
1.Application：This cable is used for interconnecting between frames of PCM equipments with 120W characteristic impedance.2. Conductor：Annealed bare copper or tinned copper3. Insulation：Foamed PE / HDPE4.Shielded：Two wires are twisted to form a pair then shielded with a layer of Al-Mylar foil. A piece of tinned copper wire is added along with the pair as drain wire.5.Assembly：Suitable number of pairs are assembled to form a cable core.6. Overall shield：a. Layer of Al-Mylar foil with a drain wire.7.Sheath：PVC (polyvinyl Chloride)or LSNHFRPE.( ow-moke Non-Halogen Flame Retardant Polyethylene).
