Description
Technical Field
The utility model relates to the technical field of optical fiber patch cords, in particular to a novel armored optical fiber patch cord.
Background
The armored optical fiber jumper can be directly laid in a machine room and various severe environments, a protective sleeve is not needed, the space is saved, the construction cost is reduced, the convenience of network maintenance is greatly improved, the biggest difference between the armored optical fiber jumper and the traditional optical fiber jumper is that the armored optical fiber jumper aims at the defect that an optical fiber is easy to break and damage, a fine flexible stainless steel sleeve is specially designed and produced to protect the optical fiber, a flame-retardant PVC coating is added outside the stainless steel sleeve to achieve the functions of moisture resistance, fire resistance and the like, but the existing armored optical fiber jumper usually directly arranges a tightly-packaged optical fiber in the stainless steel sleeve, a larger gap is left between the tightly-packaged optical fiber and the stainless steel sleeve, and as the stainless steel sleeve is formed by spirally winding a steel belt, when the bending degree of the whole armored optical fiber is larger, the steel belt at the bending point can be deformed, and the inner tightly-packaged optical fiber can be in line contact with the deformed steel belt, thereby cutting the tight-buffered optical fiber and affecting the performance of the optical fiber.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems mentioned in the background art, the utility model aims to provide a novel armored optical fiber jumper.
In order to achieve the above object, the technical scheme of the utility model is as follows:
the utility model provides a novel armored optical fiber jumper wire, includes the optical cable, the end connection of optical cable has the connector, the optical cable includes tight set optic fibre, porous bubble cotton cover, metal armor cover and oversheath, the cladding of porous bubble cotton cover is in on the tight set optic fibre, the cladding of metal armor cover is in on the porous bubble cotton cover, the oversheath cladding is in on the metal armor.
Further, the porous foam cotton sleeve is a soft polyurethane foam cotton sleeve.
Further, the metal armor sleeve is formed by spirally winding a stainless steel band on the porous foam sleeve.
Furthermore, a fiber reinforced sleeve is arranged between the metal armor sleeve and the outer sheath.
Furthermore, the fiber reinforced sleeve is formed by spirally twisting a plurality of strands of aramid fiber ropes outside the metal armor sleeve.
