Abstract
The invention discloses an armored optical cable. The optical cable comprises a casing pipe. A polyurethane sheath sleeves an outer wall of the casing pipe. An inner wall of the polyurethane sheath is provided with a plurality of buffer slots which are along an axial direction. A width of each buffer slot is gradually increased outwards along a radial direction of the polyurethane sheath. A plurality of optical fibers are arranged in the casing pipe. The plurality of optical fibers are spirally twisted on an aramid fiber pipe located on a central section of the casing pipe. A fiber paste is filled between the casing pipe and the aramid fiber pipe. When the optical cable is rolled and pressed by a vehicle or a drop stone in a field environment, the buffer slots divide a connection portion between the polyurethane sheath and the casing pipe into a plurality of protuberances. When an outer wall of the polyurethane sheath is under stress, the protuberances can be deformed in the two adjacent buffer slots. Through an interaction of an elastic force generated during deformation recovery of the protuberances and pressure, the actual pressure on the casing pipe is greatly reduced so that the optical fiber in the casing pipe is prevented from being pressed and damaged, and the service life of the optical cable in the field environment is prolonged.
Description
Technical field
The present invention relates to a kind of optical cable, specifically refer to a kind of armored optical cable.
Background technology
Military optical fiber cable for field operation is specially for using under needing fast wiring or folding and unfolding service condition repeatedly under field operations and complex environment and the metal free optical fiber cable that designs, have lightweight, be convenient for carrying; Tension stress, compressive resistance, the ratio of strength to weight are high; Flexibility is good, flexible; Oil resistant, wear-resisting, fire-retardant; The features such as Applicable temperature scope is wide, are applicable to military outdoor communication system fast wiring or folding and unfolding repeatedly; Radar, aviation and naval vessel wiring; The occasion that the conditions such as oil field, mine, harbour, TV are relayed live, communication line repairing are special.
Owing to lacking metal as supporting construction in existing optical cable, under the field environment condition of complexity, optical cable is in use difficult to avoid by weight spreading, the such as compressing of the weight such as military vehicle or mountain area dropstone, it can be caused impaired serious and lose its communication function, affect the acquisition of real-time information adversely; And field environment runs into wind and rain weather more, common optical cable cannot ensure its longer serviceable life.
Summary of the invention
The object of the present invention is to provide a kind of armored optical cable, facilitate fast wiring and the folding and unfolding repeatedly of optical cable, avoiding, there is damage by during weight compressing, improving its serviceable life simultaneously.
