Abstract
An air-blowing optical cable with high-count fiber of layer stranded type comprises a cable core and an external protective sleeve. Pluralities of loose-sleeve optical fiber transmission units are installed inside the cable core and the centre of the cable core is provided with a central reinforcing element. The optical cable has the advantages of compact structure, small external diameter, light weight, convenient construction and high efficiency, being adaptable for the air-blowing laying. In the laying time, optical fiber arranged inside the optical cable is hard to be damaged.
Description
Technical field
The utility model relates to a kind of communications optical cable, and especially the big core of layer-twisted type is counted air transporting optical cable.
Background technology
The existing layer stranded cables is not suitable for pneumatic transmission and lays because external diameter is big, Heavy Weight, and general employing traction is laid, the construction trouble, and efficient is low, also damages the optical fiber in the optical cable easily.
Summary of the invention
The purpose of this utility model provides and a kind ofly is used for the big core of layer-twisted type that pneumatic transmission lays and counts air transporting optical cable, and easy construction in laid processes, efficient height can not damage the optical fiber in the optical cable.
The big core of the layer-twisted type that the utility model provides is counted air transporting optical cable and is comprised cable core and oversheath, is provided with a plurality of loose tube fiber transmission units in the cable core, and cable core central authorities are provided with central reinforce member.
The beneficial effects of the utility model are: compact conformation, external diameter are little, in light weight, are applicable to that pneumatic transmission lays, easy construction, efficient height, and the optical fiber when laying in the optical cable is easy damaged not.
Description of drawings
Fig. 1 is the horizontal face synoptic diagram of wearing of the present utility model.
In Fig. 1,1. loose tube fiber transmission unit, 2. optical fiber, 3. fine cream, 4. loose sleeve pipe, the cable cream that 5. blocks water, 6. central reinforce member, 7. cable core, 8. oversheath.
Embodiment
In Fig. 1, adopt loose sleeve pipe 4 several optical fiber 2 of coating and fine cream 3 to make loose tube fiber transmission unit 1, the central reinforce member 6 and the cable cream 5 stranded cable cores 7 of making that block water that a plurality of loose tube fiber transmission units 1 are made with nonmetallic materials, outside cable core 7, coat the oversheath of making by the high density protective cover material 8 again, promptly make the utility model.
Claims (1)
1. the big core of layer-twisted type is counted air transporting optical cable, comprises cable core and oversheath, it is characterized in that being provided with in the cable core a plurality of loose tube fiber transmission units, and cable core central authorities are provided with central reinforce member.
