The structure of GYTA53+33 optical cable is to put 250µm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforcing core. The loose tube (and filling rope) is twisted around the central reinforcing core into a compact and round cable core. The gaps in the cable core are filled with water-blocking filler. The plastic-coated aluminum strip (APL) is longitudinally wrapped and then extruded with a polyethylene inner sheath. The double-sided plastic-coated steel strip (PSP) is longitudinally wrapped and then extruded with a polyethylene outer sheath. After being armored with single thin round steel wire, the outer sheath of polyethylene is finally extruded to form a cable.
Application：Directly buried, steep slopes, underwater
Temperature Range：Storage and operation:：-40C ~ +70C；Erection：-15C ~ +60C
Bend radius：Static 10 times the cable diameter，Dynamic 20 times optical cable diameter
Fiber Type：G652D；G655C；G657A1；G657A2；50/125；62.5/125；OM3-150；OM3-300；OM4 As Options
1、Has good mechanical properties and temperature characteristics
2、Single thin round steel wire armor gives optical cables stronger tensile properties
3、The loose tube material itself has good hydrolysis resistance and high strength
4、The tube is filled with special grease to provide critical protection for the optical fiber.
5、Good pressure resistance and softness
6、Take the following measures to ensure the waterproof performance of optical cables:
– Single steel wire center reinforcement core
– The loose tube is filled with special waterproof compound
– Complete cable core filling
– Plastic coated aluminum strip (APL) moisture barrier
– Double-sided plastic-coated steel strip (PSP) improves the moisture resistance of optical cables
– Good water-blocking material prevents longitudinal water seepage of optical cables
Standard length：2000m, other lengths are also available
Note: The structure’s size and specifications can be desianed according to customer requirements
