Description
The DCFA optical cable offers reliable performance in outdoor environments due to its advanced all-dry design. Colored optical fibers are housed in high-modulus loose tubes with excellent hydrolysis resistance, filled with thixotropic gel for complete water blocking.
A non-metallic FRP central strength member delivers robust tensile support while eliminating electromagnetic interference. The stranded loose tubes and fillers form a compact circular structure, with water-blocking yarn and tape providing additional moisture protection. A coated aluminum tape layer enhances environmental resistance, and the polyethylene outer sheath offers superior UV protection.
