GYTC8A Bundle-tube 8-shaped self-supporting optical cable


GYTC8A optical cable is to insert 250 m optical fiber into a loose sleeve made of high modulus material and fill the loose sleeve with waterproof compound. The center of the cable core is a metal reinforced core (or non-metal, such as FRP, etc.). The loose sleeve (and filling rope) is twisted around the center reinforced core to form a compact and round cable core. The cable core is longitudinally wrapped with a plastic-coated aluminium strip (APL) and integrated into an 8-shaped polyethylene sheath with steel wire strands. TTI Co., Ltd. can also provide Y sheath or S sheath of 8-shaped optical cable GYTC8Y, GYTC8S and so on. These products are mostly used in self-supporting overhead laying.

Features                   ·

Wire strand has very high tensile strength, which is convenient for self-supporting overhead laying and reduces installation cost.            ·

♦ Good mechanical properties and temperature characteristics           

Loose casing material itself has good water resistance and high strength.           

Special ointment is used in the tube to protect the optical fiber critically.           

The following measures are adopted to ensure the waterproof performance of optical cables
