Description
In OMC’s 12-48F Aerial Self-supporting Fig 8 Stranded Loose Tube Armored Cable GYTC8S, A Steel wire&PE cushion layer is located in the center of core as a metallic strength member. single-mode/multimode Fiber are positioned in the loose tube, which is made of PBT materials and filled with filling compound. There is a Corrugated steel tape covered the PBT tubes. Then a HDPE materials sheath covered the APL tape to guarantee the compactness and longitudinal water-blocking performance.
