To solve the splice loss, pay attention to the selection of high-quality optical fibers with consistent characteristics, strictly follow the requirements during construction, prepare perfect fiber end faces, correctly use the fusion splicer, etc. To solve the non-splice loss, pay attention to choosi

With the development of information transmission technology, the long-distance backbone network and user network mainly based on OPGW optical cable are forming. Due to the special structure of the OPGW optical cable, it is difficult to repair after damage, so special attention should be paid to the

What is aerial fiber optic cables?Self-supporting aerial cables, also known as all-dielectric self-supporting (ADSS) cables are bonded to insulated steel or all-dielectric messenger for support. Usually, ADSS cables are made up of heavier jackets and stronger metal. On the other hand, catenary

Directly buried fiber optic cable This kind of optical cable is armored with steel tape or steel wire on the outside and buried directly in the ground. It is required to have the performance of resisting external mechanical damage and preventing soil corrosion. Different sheath structures should be

Duct fiber optic cable laying is generally in urban areas, and the environment for pipe laying is relatively good, so there is no special requirement for the sheath of the optical cable, and no armor is required.Before the pipeline is laid, the length of the laying section and the location of the co
