Figure-8 self-supporting optical cable (GYTC8S) (GYTC8S-2~60 Xn)
The structure of (GYTC8S) stranded loose tube figure-8 self-supporting outdoor optical cable is to insert 250μm optical fibers into loose tubes made of high modulus material, with the loose tubes filled with a water-blocking compound. At the center of the cable core is a metallic strength member (which can also be non-metallic, such as FRP, etc.), and the loose tubes (and fillers) are stranded around the central strength member to form a compact round cable core. A layer of plastic-coated aluminum tape (APL) is added in a longitudinally wrapped form outside the cable core and inside the sheath, and finally extruded together with the steel strand with a polyethylene sheath, so that its cross-section is in a "8" shape.
