Description
In OMC’s 2-96F Stranded Loose Tube Armored (GYFTA) type Cable, A FRP wire, sometimes sheathed with polyethylene (PE) is located in the center of core as a No-metallic strength member. Single-mode/multimode Fiber are positioned in the loose tube, which is made of PBT materials and filled with filling compound. PBT Tubes (and fillers) are stranded around the Central strength member into a compact and circular cable core. After a APL armor is applied, The PE materials Jacket covered to guarantee the compactness and longitudinal water-blocking performance.
