GYTS outdoor fiber optic cable, is also called multi loose tube steel tape external cable, is consisted of 250um fibers held in oil filled PBT loose tubes
wrapped around a phosphatized steel wire central strength member. This is surrounded by either water blocking jelly, a aluminum tape laminated on
both sides with polyethylene and bonded tightly to the PE sheath.
Application:
– Adapted to outdoor distribution.
– Suitable for external applications in ducts and aerial applications.
– Long distance and local area network communication.
