Technical Field

The utility model relates to an optical cable technical field especially relates to a two core flat wiring optical cables of network communication.

Background

With the increasing demand of production and life for information consumption, the optical fiber communication technology is widely applied in various fields, the optical access cost is continuously reduced, the cost of copper cables and the cost of copper wire access to operation and maintenance are increased, and the networks of large and small operators are changing to the networks characterized by broadband at high speed. With the advent of more and more high bandwidth services, FTTH/FTTB (fiber to the home, fiber to the building) has become the first choice for many operators. With the deepening of informatization, great demands for gradually increasing optical cables are brought.

With the construction of 4G and cloud computing centers and the pursuit of faster, higher and more machine room construction requirements of internet enterprises, the capacity of optical fibers of the machine room is larger and larger, but the space is quite limited, and meanwhile, in order to meet the batch construction requirements of the current machine room and residential districts, the number of optical cable cores is required to be large, but the size of the optical cable is required to be small as much as possible. The wiring optical cable of the existing machine room mostly adopts branch optical cables or bunched optical cables, and the requirement cannot be met. In a residential district, since the number of districts and the number of unit buildings are large, it is impossible to lead outdoor optical cables to the lower part of each unit building, and it is necessary to lead the outdoor optical cables from an optical fiber distribution box to an optical fiber distribution box below the unit building by using wiring optical cables, and when the outdoor optical cables are fusion-spliced with the wiring optical cables in the optical fiber distribution box, the optical unit part of the wiring optical cables is easy to be caused by the fact that

The optical fiber loss abnormality is caused by the tension.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an adopt optical cable of two-core design is provided, have novel structure, long service life, the network communication two-core flat wiring optical cable of advantages such as range of application is wide.

In order to solve the technical problem, the utility model provides a two core flat wiring optical cables of network communication, include the oversheath and locate two inside optic fibre of oversheath, its characterized in that, two optic fibre are first optic fibre and second optic fibre respectively, first optic fibre has wrapped first waterproof layer, first fire-retardant layer and first inner sheath by inside to outside in proper order, second optic fibre has wrapped second waterproof layer, the fire-retardant layer of second and second inner sheath by inside to outside in proper order, the oversheath still is equipped with fire-retardant stopping.

Furthermore, a first inner sheath and a second inner sheath are arranged in the outer sheath, and flame-retardant filler is arranged at a gap between the first inner sheath and the second inner sheath.

Further, the first inner sheath and the second inner sheath are arranged in parallel.

Further, the first inner sheath, the first flame-retardant layer, the first waterproof layer and the first optical fiber are respectively identical in structure with the second inner sheath, the second flame-retardant layer, the second waterproof layer and the second optical fiber.

Furthermore, the manufacturing materials of the first inner sheath, the first flame-retardant layer, the first waterproof layer and the first optical fiber are respectively the same as the manufacturing materials of the second inner sheath, the second flame-retardant layer, the second waterproof layer and the second optical fiber.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an optical cable of two core designs has novel structure, long service life, advantages such as range of application is wide.
