Abstract

The utility model relates to an optical transmission line for communication, computers, cable TV networks and transmission information in other occasions, which is composed of an optical cable, plugs which are arranged at both sides of the optical cable and an end number tube. The upper side of the optical cable between the end number tube and the plugs is provided with a casing tube identifying member, and the utility model has the advantages of convenient use, flexibility and favorable assembly and construction and is favorable to carrying out the work of normal overhaul and maintenance. When the identification information about a certain optical cable needs to be sawn, the identification casing tube is rotated properly, so that other artificial injury accidents can not be caused; the tube diameter of the casing tube is increased relatively, annotation is easier, and the operation is standard and orderly; the service life of the transmission line is enhanced, and economy is good.

Description

Optical transmission line

The utility model relates to reach in communication, computer network, the cable TV network a kind of device of other occasion in order to transmission information.

Both at home and abroad, at present in communication, computer network, cable TV network and other occasion in order to the optical transmission line of transmission information, as D4, FC, SC type transmission line, all by optical cable, be arranged on the optical cable two ends optical connector---plug and end number pipe constitutes; Plug is in order to be connected with the adapter of Optical Distribution Frame; Whether the end pipe is only to mark the end No.1 1 of this transmission line or 2 member on it, by holding No.1 1 or 2, just can check from the optical cable label and respectively hold the corresponding techniques parameter, conform to quality requirements; The relevant identifying information that often need use as office direction, optical fiber sequence number and other relevant label of using for installation etc., directly writes near the optical cable of plug temporarily.The deficiencies in the prior art part mainly is: do not have relatively turnable member for the relevant identifying information of mark on the transmission line, be unfavorable for installation, be unfavorable for overhauling normally, maintaining work, when needs are checked relevant identifying information, usually can only be to rotate optical cable by force, cause the optical fiber of optical cable and plug inside to fracture easily, cause new human accident again, even bring great economic loss.In addition, the cable line footpath that has is thinner, and mark is difficulty comparatively, and the mark identifying information influences job specification on arbitrary orientation.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of optical transmission line product that is beneficial to maintenance, maintaining, construction and installation is provided.

Can take following technical scheme to realize purpose.This optical transmission line still is made of number pipe assembling of optical cable, the optical connector that is arranged on the optical cable two ends and end, but also is set with the identification sleeve component on the optical cable between end number pipe and the optical connector.Make and have the optical transmission line goods that can relatively rotate, supply the relevant identifying information sleeve component of mark.

Under the prerequisite that satisfies the said structure requirement, specific constructive form, size as for the integral body of optical transmission line, each funtion part, each zero member, connection between member, fixed form, the position relation, such as the type of plug of optical transmission line institute adapted, the color of identification sleeve pipe, shape, length, thickness etc. all can be taken the circumstances into consideration to set according to using needs, they can both realize purpose, guarantee the usability and the effect of this optical transmission line.

The relative prior art of the technical program has following advantage and effect:

Easy to use, flexible, be beneficial to installation, be beneficial to normally overhaul, maintaining work, when needs were checked the relevant identifying information of certain optical cable, the identification sleeve pipe that suitably rotates on it got final product, and can not cause other artificial damage accident; The sleeve pipe caliber increases relatively, mark more or less freely, job specification, neat; Improve the serviceable life of transmission line, good economy performance.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1,2,3 is respectively a kind of structural representation of D4, FC, SC type optical transmission line.

Among the embodiment of optical transmission line shown in the accompanying drawing, optical cable 1, end number pipe 2, be arranged on optical connector---the formation of plug 4 and their effect at optical cable two ends, all do not have difference, just on the optical cable between each end number pipe and the optical connector, respectively be set with an identification sleeve pipe 3 members with prior art.Identification sleeve pipe 3, the random conversion direction of optical cable relatively, in order to marking required various relevant identifying information, the relevant label of using as office direction, optical fiber sequence number and other confession installation etc.; It can adopt existing various pipe material to constitute.

The usability of accompanying drawing illustrated embodiment, result of use are good.

Claims

1, a kind of optical transmission line is made of optical cable, the optical connector that is arranged on the optical cable two ends and end pipe, it is characterized in that: also be set with the identification sleeve component on the optical cable between end number pipe and the optical connector.
