Abstract
The utility model relates to an ultraviolet-resistant outdoor armored optical cable. The ultraviolet-resistant outdoor armored optical cable comprises a communication fiber; a metal tube arranged on the outer side of the communication fiber; an aramid fiber sleeve arranged on the outer side of the metal tube; a metal mesh grid arranged on the outer side of the aramid fiber sleeve; an ultraviolet-resistant optical cable outer sheath arranged on the outer side of the metal mesh grid; and an ultraviolet-resistant metal braiding sheath arranged on the outer side of the ultraviolet-resistant optical cable outer sheath. Optical cable fillers are respectively arranged between the communication fiber and the metal tube, between the metal tube and the aramid fiber sleeve, and between the metal mesh grid and the optical cable outer sheath. The ultraviolet-resistant outdoor armored optical cable solves the problem that a conventional armored optical cable is prone to aging when used in an outdoor environment and irradiated by ultraviolet rays. By additionally arranging the ultraviolet-resistant metal braiding sheath and further adding photo aging resistant agents inside the ultraviolet-resistant optical cable outer sheath, the ultraviolet-resistant outdoor armored optical cable is better protected. Even if being exposed outdoors for long-term use, the ultraviolet-resistant outdoor armored optical cable can maintain stable operations. The service lifetime of the ultraviolet-resistant outdoor armored optical cable is further prolonged.
