DINTEK Light-LINKS™ FTTH Indoor cables are used internally in buildings or for residential applications. In the center of the cable is the optical fibers, with the two parallel non-metal enhanced FRP as the strength member, and surrounded with the LSZH jacket. Indoor FTTH cables have the same function as common indoor fiber cables, but also have some special features. FTTH indoor cables are smaller in diameter, water-resistant, soft and bendable. They are easy to deploy and maintain.
