Optical fiber cable 12 core LS Korea

LS optical fiber cables are produced in Korea. The following specifications cover the general requirements for optical fibers. The 12-core multimode cable has a sheath, which is usually PE or LSZH. Blinds are color coded. The structure of the cable is in the form of a central loose tube. It has power member, rapcord and final coating. These cables are used in channels.
