Description

A kind of optical communication system outdoor optical cable coupling arrangement

Technical field

The utility model relates to a kind of optical cable coupling arrangement, relates in particular to a kind of optical communication system outdoor optical cable coupling arrangement.

Background technology

Along with the continuous development, particularly 3G of Fibre Optical Communication Technology, the development of FTTX, a large amount of communication products are used for outdoor, the outdoor joints of optical fibre and often are applied to.To outdoor complicacy, more abominable physical environment, require the outdoor joints of optical fibre to have higher requirement at aspects such as waterproof and dustproof, high-low temperature resistant and radiation proofs.At present; The frame mode that the outdoor optical cable connector of optical communication system extensively adopts mainly contains two kinds: one, on the basis of connector LC, MTRJ and the SC of standard, increase the connector that outdoor and indoor light path is connected that satisfies that metal or the plastic cement part of function such as some water proof and dust proofs process outward with adapter through the connector of giving these standards.This mode generally is that two connectors and an adapter flange are formed.Two, public female header structure mode, public female back of head all with the optical cable good seal, perhaps only seal outdoor optical cable one end rear portion, spline location and guiding through a public female junction add a latch mechanism and push down O-ring seal.Realize that the indoor and outdoor light path connects.These two kinds of production and processing aspects are also relatively more difficult; Especially public female header structure mode, the spline processing cost at public female head place is quite big, and the inner lock pin and the location of sleeve pipe and centering structure are all comparatively complicated; Assembly technology requires than higher, causes stability and cost aspect that problem is all arranged.And this dual mode all is that the mode that outdoor cable, connector and other protection parts all are the usefulness fixed connections is assembled into an integral body, not quick detachable and replacing parts.

The utility model content

To the deficiency of prior art, the purpose of the utility model is to provide a kind of easy for installation, respond well optical communication system outdoor optical cable coupling arrangement.

For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of optical communication system outdoor optical cable coupling arrangement; Comprise optical cable, reinforcement, optical fiber, unit interface; It is characterized in that the optical fiber both sides are provided with unit interface, be provided with oversheath in the said optical cable, be provided with reinforcement in the oversheath.

Adopt the advantage of technique scheme to be; Owing to installing and having used above-mentioned optical connector piecing devices, when pullling the butterfly covered wire cable, owing to the oversheath that is the butterfly covered wire cable is stressed; Thereby improved the covered wire cable pull resistance greatly, avoided optical fiber to sustain damage well.Compare with glue covered wire cable and the bonding method of connector, not only tensile strength is high, is not subject to the external condition influence, has good long-time stability, and simple to operation.

The beneficial features of the utility model is: simple in structure, good airproof performance, easy to assembly, can effectively reduce the maintenance cost of outdoor optical connector.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further;

Fig. 1 is the structural representation of the utility model;

Among the figure, 1, optical cable, 2, optical fiber, 3, reinforcement, 4, oversheath, 5, unit interface.

Embodiment

As shown in Figure 1, a kind of optical communication system outdoor optical cable coupling arrangement comprises optical cable 1, reinforcement 3, optical fiber 2, unit interface 5; The both sides of optical fiber 2 are provided with unit interface 5; Be provided with oversheath 4 in the said optical cable 1, be provided with reinforcement 3 in the oversheath 4, the utility model is owing to install and used above-mentioned optical connector piecing devices; When pullling the butterfly covered wire cable; Because the oversheath that is the butterfly covered wire cable is stressed, thereby has improved the covered wire cable pull resistance greatly, has avoided optical fiber to sustain damage well.Compare with glue covered wire cable and the bonding method of connector, not only tensile strength is high, is not subject to the external condition influence, has good long-time stability, and simple to operation.

Claims (1)

1. an optical communication system outdoor optical cable coupling arrangement comprises optical cable, reinforcement, unit interface, optical fiber, it is characterized in that the optical fiber both sides are provided with unit interface, is provided with oversheath in the said optical cable, is provided with reinforcement in the oversheath.
