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.
♦ 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
