Air-blown Optical Cable
Microcables are installed by blowing in pre-installed buried micro-ducts. Blowing means cost reduction deployment, compared with fibre optic classic installation methods (duct, directly buried, or ADSS). There are several advantages in the blowing cable technology, but main one is rapidness, and ...Read more -
How To Improve The Thermal Stability Of OPGW Cable?
Common measures to improve the thermal stability of OPGW optical cables: 1. Shunt line method The price of OPGW optical cable is very high, and it is not economical to simply increase the cross-section to bear the short-circuit current. It is commonly used to set up a lightning protection wire p...Read more -
