Abstract
A full-dry optical fiber composite cable comprises an electric power lead in a cable core and a central tube type optical unit, wherein an optical fiber and a dry water-blocking object are arranged in a loose tube of the optical unit; the other structure is as follows: the optical unit comprises a plurality of loose tubes, water-blocking yarns, a central reinforcing member and a filling rope, wherein the loose tubes are internally provided with optical fibers and dry water-blocking objects, and the water-blocking yarns, the central reinforcing member and the filling rope are arranged in the optical unit. The utility model discloses can prevent steam to the erosion of light unit, guarantee communication quality, make light unit not have the oleamen to flow when the switching again, do not cause the pollution to environment and operator.
Description
Technical field
The utility model relates to a kind of the Optical Fiber Composite cable that has optical fiber communication function and electric power transfer function concurrently, especially dry type Optical Fiber Composite cable.
Background technology
Adopt generally in the existing fiber composite cable that the way of factice for filling reaches the purpose that the light unit blocks water in the light unit.The characteristic that has vertical drip because of ointment; therefore in the bigger cable laying section of high low head, ointment flows to lower the light unit in the cable in, thereby makes the light unit in the Optical Fiber Composite cable of eminence lack ointment protection; make optical fiber be subject to moisture attacks, and then influence communication.In addition, the light unit is when switching, and ointment wherein can flow out, and easily environment and operator is polluted.
Summary of the invention
In order to overcome the deficiency of existing fiber composite cable, the utility model provides a kind of dry type Optical Fiber Composite cable, can stop the erosion of steam to the light unit, guarantees communication quality, makes the light unit not have ointment to flow out when switching again, does not pollute.
A kind of dry type Optical Fiber Composite cable that the utility model provides comprises electrical lead and central tubular light unit in the cable core, is provided with optical fiber and dry type water-blocking material in the loose sleeve pipe of light unit.
The another kind of dry type Optical Fiber Composite cable that the utility model provides comprises electrical lead and layer-twisted type light unit in the cable core, and the light unit contains the loose sleeve pipe of establishing optical fiber and dry type water-blocking material in several and water blocking yarn, central reinforce member, gasket for packing.
The beneficial effects of the utility model are: can stop the erosion of steam to the light unit, guarantee communication quality, make the light unit not have ointment to flow out when switching again, environment and operator are not polluted.
