With a large number of client accesses and use of optical fiber cable, at the end of optical fiber cable, it needs to protect the fiber connective joint, store spare fiber and fix the cable. Due to various types of fiber cable, the cable size produced by each company is different as well; it will bring inconvenience to end customers.
GL-FN-3/4 FTTH Fiber Socket has many usages, it could connect with many kinds of cables by Multi-mode, and fix fiber and optical cable firmly, pull-out force is above 50N, the optical cable can be fixed safely, will not damage fibers and bring additional insert loss, to protect optical cable and reduce the risk of damage; easy to operate and low-intensity in construction.
