Abstract
The utility model discloses a high-tension indoor wiring optical cable which is characterized in that the optical cable includes optical units, the periphery of the optical units is coated with a wrapping layer, a drainage wire is arranged in the wrapping layer and among the optical units, and the wrapping layer is externally coated with an inner sheath layer, a high-tension fiber reinforced layer, a metal armor layer, a flame-retardant layer and an outer sheath layer in sequence. The high-tension indoor wiring optical cable has the following advantages: the tension resistance of the optical cable is significantly increased, damage of tension-resistant fibers to the optical units is avoided, the optical cable has good flame-retardant performance, and the quality of the optical cable and normal and reliable operation of optical communication are ensured.
Description
Technical field
The utility model relates to the optical communication optical cable, relates in particular to a kind of great tension indoor wiring optic cable.
Background technology
For further improving the resistance to tension of optical cable, the structure of existing house wiring optical fiber cable has all adopted light unit peripheral shaft to having laid the fibrous bundles such as terylene, polyamide fibre, nylon, in its periphery, adds one deck plastic sheath and is protected.In prior art, cable outer sheath often is subject to axial tractive, easily with light unit and the fibrous bundle of the inside, produce relative slippage, fibrous bundle and the contracting of light unit are inside, easily make light unit and optical fiber impaired, because oversheath can only encase loosely to light unit and fibrous bundle, can't play collaborative light unit and strengthen resistance to tension; And fire resistance is not high, easy fracture.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
The utility model content
The purpose of this utility model is to provide a kind of great tension indoor wiring optic cable.
The technical solution adopted in the utility model is:
A kind of great tension indoor wiring optic cable, it is characterized in that: comprise the light unit, periphery, described smooth unit is coated with lapping layer, in described lapping layer, be provided with drainage thread between the light unit, described lapping layer is coated with inner restrictive coating, hightension fabric reinforcement, metal armouring layer, flame-retardant layer and external sheath layer outward successively.
Between described lapping layer, inner restrictive coating, hightension fabric reinforcement, metal armouring layer, flame-retardant layer and external sheath layer, be the combination that is tightly fixed.
The quantity of described smooth unit is single.
The quantity of described smooth unit is a plurality of, closely cooperates between described smooth unit.。
The utility model has the advantages that: significantly strengthened the strain insulator ability of optical cable, avoided the damage of strain insulator fiber to the light unit, fire resistance is good, guarantees the quality of optical cable and the normal reliable operation of optical communication.
