Loose tubes made of color coating fibers and filled with waterproof compounds. Loose tube are stranded around the strength member which in the central of cable into cable core, a layer of water-blocking tap is longitudinal wrapped around the cable core, and then an outer jacket is extruded.
SM: G652D、G655、G657 Or other single-mode optical fibers. MM: A1a、A1b Or other multi-mode fibers.
Materials: polyethylene (PE), low smoke halogen-free flame retardant polyolefin (LSZH), flame-retardant polyethylene (ZRPE) or other material. Color: black or other colors.
Can be used in Duct,Non-self-supporting aerial.
Good mechanical and environmental performance. High strength loose tube that is hydrolysis resistant . All-dielectric structure has strong ability to resist electromagnetic interference. Small structure,light weight, easy to lay, saving precious duct resources.
