Outdoor Fiber Cable-GYTC8A

Configuration & Physical characters

The fibers,125μm, either of single-mode or multimode type, are positioned in PBT tube  The tubes are filled with a water-resistant filling compound. Tubes stranded around the central steel strength member. Then, the cable is completed with a black or color PE sheath. Stranded steel wire as additional strength member with self supporting function.
