Description
In the structure of Model GYXS optical cable, the single mode or multimode optical fibers are jacked by loose tube and the tube made of high modulus polyester. Inside the tube, it is full of waterproof filling compound. Outside the loose tube, it is wrapped longitudinally by a layer of both sides plastic coated ripple steel tape and loose tube is used to ensure compact optical cable structure and longitudinal waterproof. There are two parallel steel wires on the two sides of the loose tube and they are sheathed by PE to form an optical cable.
Features:
. The medium density PE sheath features perfect mechanical strength, waterproof, abrasive resistance and good environmental stress cracking performance.
. The longitudinally wrapped both side plastic coated steel tapes and waterproof tape could effectively prevent tube from shrinking and improve optical cable waterproof, penetration resistance and moisture-proof.
. It is convenient in construction as its small diameter, light weight, and perfect performance-price ratio.
. The remaining length of optical fiber is controlled precisely to ensure perfect tensile strength and temperature characteristics of the optical cable.
. The loose tube material itself has perfect hydrolysis resistance and high strength.
. The special filling paste inside the loose tube is used to protect the optical fiber.
. The fibers, 250μ M, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube, the water-blocking material is applied to keep the cable compact and watertight.
