Home>Products>Outdoor Optical Cables>Loose tube layer-strand non-metallic armored optical cable.
The GYFTA53 optical cable is constructed by embedding 250μm optical fibers into a loose tube made of high-modulus material, filled with a water-blocking compound. The core center contains a non-metallic strength member. For certain fiber counts, an additional polyethylene (PE) layer is extruded over the non-metallic strength member. The loose tubes (and filler rods if applicable) are stranded around the central strength member to form a compact and circular cable core, with gaps filled with water-blocking material. A plastic-coated aluminum tape (APL) is longitudinally applied before extruding an inner PE sheath, followed by a double-sided plastic-coated steel tape (PSP) longitudinally applied and an outer PE sheath extruded to complete the cable.
