The technical scheme of the utility model is realized as follows:
The utility model provides an indoor outer general optical cable, includes the cable core, the outside of cable core is equipped with water blocking tape, bundle yarn, metal spiral armour pipe, sheath from inside to outside in proper order, the scarf joint of sheath is equipped with the steel wire purse seine.
According to the technical scheme, the metal spiral armor tube and the steel wire purse net embedded in the sheath are arranged outside the cable core, so that double-layer protection is achieved, the overall anti-gnawing strength of the optical cable is effectively improved, and the internal optical fiber is prevented from being damaged by rodents engaged with teeth; in addition, the adoption of the metal spiral armor tube can also improve the anti-flattening capacity and the mechanical property of the optical cable.
In such indoor and outdoor optical cables of the present utility model, the cable core includes a water blocking yarn, a central reinforcing member, an optical fiber unit including a loose tube, a plurality of colored coated optical fibers positioned within the loose tube, and an ointment filled within the loose tube.
In the indoor and outdoor general optical cable of the present utility model, the number of the water blocking yarns is two, and the water blocking yarns are symmetrically arranged on the outer sides of the circumference of the central reinforcing member; the optical fiber units are four and are arranged around the central reinforcing member.
In such indoor and outdoor utility fiber optic cables of the present utility model, the central strength member is made of a fiber reinforced composite material.
In the indoor and outdoor universal optical cable of the present utility model, the loose tube is made of PBT material.
In the indoor and outdoor general optical cable of the present utility model, the binder yarn is a high modulus aramid yarn.
In the indoor and outdoor universal optical cable of the utility model, the wire purse net is embedded in the sheath in three layers.
The indoor and outdoor general optical cable has the following beneficial effects: the metal spiral armor tube and the steel wire purse net embedded in the sheath are arranged outside the cable core, so that double-layer protection is achieved, the overall anti-gnawing strength of the optical cable is effectively improved, and the inner optical fiber is prevented from being damaged by rodents engaged with the optical cable; in addition, the adoption of the metal spiral armor tube can also improve the anti-flattening capacity and the mechanical property of the optical cable.
