Application

This cable can provide excellent transmission performance and protection of fibers in a variety of fi eld environments. It is usually used in long haul communication system, subscriber network system, distribution, feeder network system and local area network system.

    Description

Central loose tube cable contains one tube with 12 fi ber ribbons, which is fi lled with water blocking gel. The fi ber ribbon can be easily separated by hand tool. Either aramid yarn or fi ber glass is wound around the tube to provide physical protection and tensile strength. The cable can be jacketed with either PE, PVC or LSZH though PE is the preferred option for water protection purpose. For direct burial, steel wire armour or corrugated steel tape armour is applied with an optional inner jacket of either PVC or PE. An optional Aluminium moisture tape can be incorporated under the jacket for water blocking and shielding purpose. An optional ripcord can be put under the jacket to facilitate jacket removal.
