Abstract

The utility model relates to a novel covered wire wiring cable suitable for a plurality of indoor and outdoor environments. The cable comprises fibers, reinforced pieces, flame retardation sheaths and a flame retardation outer sheath; the cable is characterized in that the fiber and steel wire reinforced pieces are arranged in the flame retardation sheath to form a covered wire cable; and a plurality of covered wire cables are twisted together for wrapping and are wrapped by the flame retardation outer sheath. The novel covered wire wiring cable is provided; cables of covered wire metal reinforced pieces are fully employed inside, and are then wrapped and twisted as a whole body, finally are wrapped by the flame retardation outer sheath; and the produced covered wire wiring cable is big in stretch-proofing intensity, and can be used in a plurality of indoor and outdoor environments.

Description

The Novel covered wire optical distribution cable

Technical field

The utility model relates to the optical cable technology field, definite says a kind of optical distribution cable that is comprised of many covered wire cable unit.

Background technology

At present, in Communication in China, computer information industry field, along with finishing of China Telecommunications Trade's restructuring, promoted the development of optical-fiber network.Especially in the construction of Access Network, the indoor large core number that density of optic fibre is high, optical cable intensity is large is used optical cable and will be promoted the use of on a large scale.The use of original optical distribution cable or independent covered wire cable can't be satisfied more environmental requirement.

Summary of the invention:

The purpose of this utility model provides a kind of Novel covered wire optical distribution cable, compares with the conventional cable of identical core number, and it is little that it has physical dimension, lightweight, and cost is low, good bending property, and integrated level is high, and density of optic fibre is large, the characteristics such as constructability.

Technical scheme is as follows: the Novel covered wire optical distribution cable, it comprises optical fiber, reinforcement, fire retardant jacket, fire-retardant oversheath, it is characterized in that: optical fiber and steel wire reinforcement form covered wire cable in fire retardant jacket, a plurality of covered wire cables are stranded wrapped to carrying out together, and the outside is wrapped up by fire-retardant oversheath.

The utility model has the advantages that:

1, the physical dimension of novel optical distribution cable is little, and cross-sectional area dwindles;

2, reduce with traditional optical distribution cable structure compared, weight just lightens, and makes things convenient for engineering construction and transportation;

3, integrally-built reducing, starting material are used greatly and reduce, and it is a lot of to have made cost;

4, external diameter is little, and is lightweight, and it is little to take up room, and usually will utilize the engineering of a lot of optical cables can save a lot of spaces now;

5, with optical fiber production be covered wire cable with reinforcement, increased whole tensile resistence, more be applicable to the various environment that lay;

6, good bending property; Integrated level is high, and density of optic fibre is large, constructability;

7, client's purchase cost is low, and executive cost is low, and the networking expense is low;

8, be suitable for body inside, building, make things convenient for the customer to construct.

Fig. 2 is the utility model production technological process.

Embodiment

It comprises optical fiber, reinforcement, fire retardant jacket, fire-retardant oversheath, and optical fiber 1 and steel wire reinforcement 2 are at fire retardant jacket 3 interior formation covered wire cables, and a plurality of covered wire cables are stranded wrapped to carrying out together, and the outside is wrapped up by fire-retardant oversheath 4.

Production technology is as follows:

At first optical fiber 1 is become covered wire cable at fire retardant jacket 3 inner sheaths together with steel wire reinforcement 2, then covered wire cable is carried out wrapped strandedly, last whole carry out oversheath with fire-retardant oversheath 4.

Claims (1)

1. Novel covered wire optical distribution cable, it comprises optical fiber (1), reinforcement (2), fire retardant jacket (3), fire-retardant oversheath (4), it is characterized in that: optical fiber (1) and steel wire reinforcement (2) form covered wire cable in fire retardant jacket (3), a plurality of covered wire cables are stranded wrapped to carrying out together, and the outside is wrapped up by fire-retardant oversheath (4).
