Description of GJYX (F) HA fiber, duct bow type drop cable

The GJYX (F) HA fiber, duct bow type drop cable is easy to install and connect, and features a water/damp resistance, high insulation, and wear resistance and is exceptionally strong. Strengthened PE material sheathes are generally stronger and more wear resistant than general cables, and the sheath will protect the optical fiber by reducing negative effects from the surrounding environment. The transmission performance thereby remains unaffected by bad environmental conditions.

Application

This product is mainly used in pipeline construction and is suitable for low-density and loose users.

Features
There is no gel used in this optical cable, making it lightweight and easy to install or connect. The metal tube is located at the access port and connection point, and will protect the optical cable from breaking when it is used. Composite aluminum-plastic tape & water-blocking yarn will efficiently protect the optical fiber in humid environments. Our optical cable is water and moisture resistant. This product is resistant to rodent interference. A strengthened PE material sheath is stronger and more wear resistant than a general cable. The transmission performance will not be affected by bad environmental conditions.
