GJSFJBV Indoor Double Core Armored Optical Cable


GJSFJBV cable structure is a parallel optical cable with a cross-section of “8″ shaped by wrapping a layer of flat stainless steel wire armor around the surface of 900 or 600 micron tightly packed optical fibers, uniformly placing multiple strands of aramid fibers outside the armor layer, and then extruding the flame retardant sheath.


♦ Multi-core optical cable with flat steel wire armor can improve the compressive and rodent resistance of optical cable.

♦ High strength aramid reinforced, high performance sheath material outer cover.         

♦ Light weight, soft, flexible, easy to connect.         

♦ It has good mechanical and environmental performance.           

♦ Flame retardant or non-flammable exterior protection, providing good safety protection


Comply with Standard YD/T 1258.2-2003, ICEA-596, GR-409, IEC794, etc.

Meet the requirements of UL approval for OFNR and OFNP.
