Abstract
The object of the utility model is to provide a microbeam circular cable, relating to the field of optical cable manufacture. The microbeam circular cable includes an outer sheath, a reinforcer, a microbeam tube and optical fibers. A plurality of optical fibers are disposed in the microbeam tube. The microbeam tube is disposed in the reinforcer. The reinforcer is disposed in the outer sheath. The microbeam circular cable provided by the utility model has the advantages of good mechanical properties, relatively small bending radius, relatively small outer diameter, light weight, convenient operation and low construction cost.
Description
Technical field
The utility model relates to fiber optic cable manufacture field, is specifically related to the circular cable of a kind of microbeam.
Background technology
Be the epoch of a network information fast development now, the development of infotech certainly will require to provide on optical device producer and network operation large capacity, fast optical communication service.But existing butterfly cable, single core cable, circular cable etc., be only a core or two cores, and core number is too small; And outdoor high fiber count cable fire resistance, bending property can not meet the demands, indoor branching, pencil cable external diameter are bigger than normal again in some occasion.
summary of the invention
The purpose of this utility model is to provide the circular cable of a kind of microbeam, has good mechanical property, has less bending radius, and external diameter is less, and lighter weight, easy to use, and construction cost is low.
The circular cable of a kind of microbeam, comprises oversheath, reinforcement, microbeam pipe and optical fiber, and several optical fiber is located in microbeam pipe, and described microbeam pipe is located in reinforcement, and described reinforcement is located in oversheath.
Described optical fiber is true qualities optical fiber or colored optical fiber.
The quantity of described optical fiber is 2-12 root.
Described oversheath is LSZH oversheath.
Described reinforcement is aramid fiber reinforcement.
The utility model mainly contains following advantage:
1. compared with common pencil cable, the utility model, in guaranteeing better mechanical property, has less bending radius, and external diameter is less, and lighter weight, easy to use, and construction cost is low;
2. compared with common microbeam pipe, physical strength of the present utility model outclass microbeam pipe, can directly use in the horizontal or vertical wiring of indoor and outdoor;
3. compared with typical circular cable, the utility model external diameter, quality etc. comparatively speaking, there is no too large difference, but its core number will obviously be better than circular cable.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model, wherein 1-oversheath, 2-reinforcement, 3-microbeam pipe, 4-optical fiber.
Embodiment
In conjunction with Fig. 1, structure of the present utility model is described.
The circular cable of microbeam, comprises that oversheath 1, reinforcement 2, microbeam pipe 3 and 4,2 to 12 optical fiber 4 of optical fiber are located in microbeam pipe 3, and microbeam pipe 3 is located in reinforcement 2, and reinforcement 2 is located in oversheath 1.Optical fiber can be that true qualities optical fiber can be also colored optical fiber.Optical fiber 4 quantity can be selected according to actual needs.Oversheath 1 size and conventional circular cable are similar.
The xsect of oversheath is circular, the preferred LSZH oversheath of oversheath, and LSZH is the english abbreviation of low smoke and zero halogen material.Reinforcement is preferably aramid fiber reinforcement.The circular cable of microbeam adopts hemicompact pack arrangement.Hemicompact pack arrangement is between hard-pressed bale structure and loose tube structure.Be that microbeam pipe can be relatively movable in oversheath, but scope of activities is little again.
In the utility model, optical fiber is responsible for communicating optical signals separately, can directly be connected to optical signal equipment by corresponding joint.Microbeam pipe 3 is for directly protecting optical fiber 4, and reinforcement 2 and oversheath 1 are for the protection of microbeam pipe 3.
Claims (5)
1. the circular cable of microbeam, is characterized in that the circular cable wrap of described microbeam draws together oversheath, reinforcement, microbeam pipe and optical fiber, and several optical fiber is located in microbeam pipe, and described microbeam pipe is located in reinforcement, and described reinforcement is located in oversheath.
2. the circular cable of microbeam according to claim 1, is characterized in that described optical fiber is true qualities optical fiber or colored optical fiber.
3. the circular cable of microbeam according to claim 2, the quantity that it is characterized in that described optical fiber is 2-12 root.
4. the circular cable of microbeam according to claim 3, is characterized in that described oversheath is LSZH oversheath.
5. the circular cable of microbeam according to claim 4, is characterized in that described reinforcement is aramid fiber reinforcement.
