Description

A kind of feed optical cable

Technical field

The utility model relates to a kind of optical cable, relates in particular to a kind of feed optical cable.

Background technology

Existing a lot of optical cable does not possess the feed function, the relay station in the optical communication system, and optical communication electronic components such as electro-optic detector are in operation and all need power supply; To give these optical communication electronic component power supplies, just must carry out the secondary wiring, so just bring the work of repetition to wiring process; Cause unnecessary human and material resources, the waste of financial resources; The environment particularly desirable at non-transformer or power taking is difficult, there is a lot of difficulties especially in the secondary wiring, and wiring is very inconvenient.

The utility model content

The purpose of the utility model is to overcome the shortcoming of prior art, and providing a kind of can be the feed optical cable of the optical communication electronic component power supply in the optical communication system when transmitting optical communication.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:

A kind of feed optical cable comprises the outer fire-retardant sheath that cable core is outer with being coated on cable core, and said cable core comprises fiber unit and two feed lines, and the space between said fiber unit and the feed line is provided with water blocking yarn, and said fiber unit comprises optical fiber.

Said fiber unit also comprises and is coated on the outer loose sleeve pipe of optical fiber and is filled in the fine cream in the loose sleeve pipe.

Said optical fiber is tightly packaged fiber, and said fiber unit also comprises aramid yarn and is coated on tightly packaged fiber and fire-retardant overcoat in aramid yarn is outer.

Said feed optical cable also comprises the water blocking layer that is arranged between said cable core and the outer fire-retardant sheath.

Said water blocking layer is made up of wrapped waterstop outside cable core, and said outer fire-retardant sheath is coated on outside the said water blocking layer.

Said cable core also comprises a gasket for packing and a central reinforce member, and said fiber unit and feed line and gasket for packing are stranded around the central reinforce member left and right sides.

Said outer fire-retardant sheath is circular.

Said outer fire-retardant sheath is flat-shaped, and said two feed lines are emitted in the outer fire-retardant sheath side by side, and said fiber unit is provided with two, and said two fiber units are arranged at respectively in the space of the middle both sides of two feed lines.

After adopting technique scheme; During use; Because optical communication information is transmitted the optical fiber of carrier and the feed line of power supply carrier is present in the cable jointly; Make that the utility model feed optical cable can also be the power supply of the optical communication electronic component in the optical communication system when transmitting optical communication, thereby need not the secondary wiring, and wiring process saves time and convenience.
