Color:
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.

Separability |
The fiber optic cable is easy to separate. After the fiber optic cable is separated, the coloring of the fiber is not obviously peeled off, and the fiber is not easy to be drawn out from the remaining fiber optic cable |
