Indoor FTTH Flat Cable 1/2/4 Cores Single Mode GJXFH Drop Fiber Optical Cable

Description GJXFH (GJXFV) [Non-metal reinforcing member, low-smoke halogen-free (or PVC) outer sheath, butterfly drop cable] The structure of the optical cable is to place the optical fiber (or optical fiber ribbon) between two parallel strengthening members and then extrude a layer of flame-retardant polyolefin sheath (LSZH), or polyvinyl chloride (PVC) sheath; the number of fiber cores can be 1-core, 2-core, 4-core. Features ●Optical cable has small outer diameter, light weight and low construction cost ●Using cold connection technology, fast connection speed ●Optical cable has a high resistance to flattening and tension ●Glass reinforced fiber rods (G-FRP), aramid reinforced fiber rods (K-FRP) or thin steel wires are used as reinforcements, and the optical cable is soft and has good bending performance ●Using LSZH or PVC flame-retardant materials to meet the flame-retardant and environmental protection performance requirements of optical cables used indoors ●The optical fiber adopts the bending loss insensitive optical fiber that meets the requirements of ITU-T G.657A&G.657B standard, and the minimum bending radius is 15mm or less. Application:
  • FTTH, indoor available
