Most of the existing MPO optical fiber jumpers adopt 16-core optical cables; when the optical fiber stripping device is used, optical fibers need to be stripped separately on site, then the optical fibers are combined in sequence and then the optical fibers are inserted into a tube, and a steel tube is used for packaging at the joint of the tail end of the inserted tube and the stripped end face of the optical fibers; the problem of complicated installation exists, and the phenomenon of wrong abnormity of the parallel-belt line sequence is easy to occur.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the existing MPO optical fiber patch cord mostly adopts a 16-core optical cable; when in use, the optical fiber is required to be separately stripped on site, then the optical fiber is combined in sequence and then the tube is penetrated, and the joint of the tail end of the penetrating tube and the stripped end face of the optical fiber is encapsulated by using a steel tube; there is the loaded down with trivial details problem of installation, appears easily and takes the technical problem of line preface mistake abnormal phenomenon, the utility model provides a following technical scheme:

the utility model relates to an MPO-Jumper optical fiber movable connecting line, which comprises a main optical cable, wherein one end of the main optical cable is provided with an MPO joint; the other end of the main optical cable is provided with a through pipe, and a wire core in the main optical cable penetrates out of the through pipe and is split into a plurality of independent ribbon optical cables; and the outer end part of the ribbon cable is connected with a jumper joint.

As a preferable technical solution of the present invention, the ribbon merging optical cable is provided with four, and is a first TX ribbon merging optical cable, a second TX ribbon merging optical cable, a first RX ribbon merging optical cable, and a second RX ribbon merging optical cable.
