GYTA Outdoor Underground Single Mode Un-Armoured Optical Fiber Cable

Product Description

Name: GYTA Fiber Optical Cable 

The fiber optic cable GYTA'S fibers, 200/250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a PE jacket.

Features of GYTA Fiber-optic Cable

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.

Applications of GYTA Fiber-optic Cable
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.

Advantages of the GYTA Fiber Cable
The GYTA fiber cable's design promotes high performance and reliability. The multi-loose tube structure, along with aluminum polyethylene laminated tape, offers excellent protection against mechanical damage and environmental stress. This robust construction allows the cable to perform reliably even in harsh conditions. Moreover, the waterproof compound and polyethylene sheath further enhance durability by shielding the cable from moisture and physical damage. As a result, the GYTA fiber cable proves to be an excellent choice for both indoor and outdoor applications. It consistently delivers dependable performance, making it suitable for a wide range of networking needs.
