What We Should Know About FTTH Drop Cable?
Drop Optical Cable is also called Bow-type drop cable (for indoor wiring). The optical communication unit (optical fiber) is placed in the center, and two parallel non-metallic strength members (FRP) or metal strength members are placed on both sides. Finally, extruded black or white , Gray polyv...Read more -
Three core technical points of OPGW optical cable
OPGW is more and more widely used, but its service life is also a concern of everyone. If you want a long service life of optical cables, you should pay attention to the following three technical points: 1. Loose Tube Size The influence of the size of the loose tube on the lifetime of the OPGW ca...Read more -
OPGW and ADSS cable Construction Plan
As we all know that OPGW optical cable is built on the ground wire support of the power collection line tower.
