1.General Description

1.1 ,The fibre optic cable is a totally non-metallic structure and immune to any RF interference. The central tube is filled with thixotropic jell which allows for excellent sustained reliability over a wide temperature range, and is engineered to ensure the optical fibres remain stress free over the designated temperature range. The aramid yarn increase the tensil strength as well as for resistance to moisture ingress. The HDPE(High Density Polyethylene) sheath is UV stabilised for outdoor applications.

1.2, This cable is designed for outdoor aerial installation,or installation into micro duct. The span is up to 50m in aerial installation.

1.3, This cable has mature and stable production engineering, strict requirements of quality control, scheduled validation product performance to ensure the product reliability., the cable has up to life-span of 25 years.
