The structure underground duct GTYA fiber optic cable is that the single-mode optical fiber is sheathed in a loose tube made of high modulus plastic, and the tube is filled with a water blocking compound. The center of the cable core is a metal steel wire as central strength member to make the fiber high with higher tensile force. A layer of polyethylene needs to be extruded outside the metal reinforced core, and the loose tube (and filler rope) is twisted around the central reinforced core to form a compact and circular cable core, the gaps in the cable core are filled with water blocking fillers.
GYTA fiber optic cable is constructed with 250 micron fibers packed into a loose casing made of high-modulus material, filled with a waterproof compound. The center of the cable core is a metal reinforced core, for some fiber optic cable core number, metal reinforced core outside also need to squeeze a layer of polyethylene (PE). Loose casing (and filling rope) is twisted around the center stiffener to form a compact and round cable core, with gaps in the core filled to block water filler. APL coated aluminum strip (APL) longitudinally wrapped and extruded polyethylene sheathed cable.
The Fiber Cores of GYTA Fiber Cable is from 2 cores to 288 cores
GYTA (metal strengthening member, loose tube stranded and filled, aluminum-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath single-mode or multi-mode optical fiber into the inner filling made of high modulus plastic Waterproof compound in loose tube. The center of the cable core is a metal reinforced core. For some fiber optic cables, the metal reinforced core is also extruded with a layer of polyethylene (PE). The loose tube (and filling rope) is twisted around the central reinforcing core to form a compact and circular cable core, and the gaps in the cable core are filled with water blocking compounds. The aluminum-plastic composite tape is longitudinally wrapped and then extruded with a polyethylene sheath.
GYTA fiber optic cable is used for duct or aerial fields. These aluminum tape armored cables are suitable for installation for long haul communication and LANs, especially suitable for high requirements of moisture resistance environment.
