FTTB Indoor Fiber Optic Cable is loose tube multi-cores micro-tube fiber cable. The cable counts is up to 288 cores. The sub-fiber cable is composed of micro tubes optical unit with reinforced with colored LSZH material. The fiber glass is single mode bending type G657A1.
Two FRP tubes are used as tensile elements at the two sides. The cable outer sheath is made of flame-retardant white LSZH, and two protruding lines are added on the surface of the cable sheath which is used for cable positioning identification when branching the core.
