GJFJH(GJYFJH/GJYFJCH) non-metallic strength member, LSZH sheath, non-self-supporting round optical drop cable (or self-supporting round optical drop cable), the optical cable is directly covered with high bonding strength outside the single-mode or multi-mode fiber The tight sleeve material is made of tight sleeve fiber, which uses high-strength aramid as the strengthening element, and is made by extruding a layer of LSZH on the outside. The structure of the self-supporting circular optical drop cable is to increase the metal steel strand suspension wire.
