Abstract
The utility model relates to the technical field of optical cables, and especially relates to a mini-sized central beam tube type lead-in optical cable which structurally comprises fiber optic bundles, fiber paste and a sleeve, wherein the fiber optic bundles are disposed in the fiber paste; the sleeve sleeves the fiber paste; an aramid yarn fiber armor layer is wound around the sleeve; an outer sheath sleeves the aramid yarn fiber armor layer; and a marker belt is disposed between the aramid yarn fiber armor layer and the outer sheath. The mini-sized central beam tube type lead-in optical cable has good tensile property and is convenient for identification and easy to strip and branch.
Description
Technical field
The utility model relates to optical cable technology field, particularly small-sized central beam tube type leading in cable.
Background technology
Small-sized central beam tube type leading in cable belongs to into house type optical cable, and as to the optical cable of last hundred meters of accesses of family, its condition of laying is extremely complicated, the foundation that often needs to fit, through porthole and through the path of laying of the multiple bendings such as wiring conduit.
The situation that optical cable is easily pullled in fiber cable laying process, and the middle-size and small-size central beam tube type leading in cable of prior art is due to the deficiency of tensile force, optical cable is easy to damage, thereby causes Optical Fiber Transmission unstable.
Prior art in manufacture process optical cable just outside jacket outer surface be printed with the label layer for identifying, and label layer is prone to the situation that lettering is unintelligible, lettering is worn, make in actual use, between many optical cables, easily occur obscuring, be unfavorable for staff's construction, and be not easy to staff's later maintenance.
Summary of the invention
The utility model provide a kind of tensile property strong, be convenient to staff's identification, and be easy to the small-sized central beam tube type leading in cable of stripping branch.
Provide small-sized central beam tube type leading in cable for this reason, comprise fibre bundle, fine cream and sleeve pipe, fibre bundle is arranged in fine cream, casing pipe sleeve is located at outside fine cream, sleeve pipe is wound with aramid yarn fiber armor outward, aramid yarn fiber armor overcoat has oversheath, between aramid yarn fiber armor and oversheath, is provided with mark band.
Wherein, between aramid yarn fiber armor and oversheath, be provided with and tear rope.
Wherein, the external diameter of oversheath is less than 5mm.
Wherein, oversheath is LSZH oversheath.
The utility model is provided with aramid yarn fiber armor, strengthened the tensile property of optical cable, in fiber cable laying process, can not damage optical cable because pullling, guarantee the stability of Optical Fiber Transmission, between aramid yarn fiber armor and oversheath, be provided with mark band simultaneously, mark band is in oversheath, mark band can not be worn, even if the label layer lettering of oversheath outside surface is unintelligible or be worn, staff still can be with identification optical cable by identification after tearing oversheath, there will not be situation about obscuring, be convenient to staff's normal construction and later maintenance.Further, between aramid yarn fiber armor and oversheath, be provided with and tear rope, during branch, only need to tear by tearing rope, be easy to stripping branch.
To sum up, the utlity model has good tensile property, guarantee the stability of Optical Fiber Transmission, the utlity model has easy stripping branch, easy to identify, constructability and maintenance simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of small-sized central beam tube type leading in cable.
Embodiment
Small-sized central beam tube type leading in cable, comprise fibre bundle 1, fine cream 2 and sleeve pipe 3, fibre bundle 1 is arranged in fine cream 2, sleeve pipe 3 is sheathed on outside fine cream 2, and sleeve pipe 3 is outer is wound with aramid yarn fiber armor 4, and aramid yarn fiber armor 4 overcoats have oversheath 5, between aramid yarn fiber armor 4 and oversheath 5, be provided with mark band 6, between aramid yarn fiber armor 4 and oversheath 5, be provided with and tear rope 7, the external diameter of oversheath 5 is less than 5mm, and oversheath 5 is LSZH oversheath 5.
