Based on the above technical solution, the utility model can also do following improvement.

Further, the fiber support part includes ferrule and optical fiber tail pipe, one end of the ferrule with it is described One end of optical fiber tail pipe connects, and the hole A is opened on ferrule and runs through the ferrule, and the hole B is opened in institute It states on optical fiber tail pipe and runs through the optical fiber tail pipe.

Processing structure is further simplified using the advantageous effect of above-mentioned further scheme, it is only necessary to which the pipe of two clear openings is Can, difficulty of processing is further decreased, production cost is saved, shortens process time, improves production efficiency.

Further, the fiber cores at least there are two, be respectively arranged in each fiber cores there are one fibre cladding, two The fibre cladding runs through the hole A, and be located at outside the fibre cladding one section of two fiber cores is respectively positioned on the hole B It is interior.

It is suitable for the optical fiber pigtail structure of multi-fiber using the advantageous effect of above-mentioned further scheme, it is applied widely.

Further, the sum of diameter of at least two fibre claddings is less than or equal to the diameter of the hole A.

The fiber cores for being arranged with fibre cladding are made to be easier to stretch into the A of hole using the advantageous effect of above-mentioned further scheme.

Further, the sum of diameter of at least two fiber cores is less than or equal to the diameter of the hole B.

Advantageous effect using above-mentioned further scheme is that the fiber cores being located at outside fibre cladding is made to be easier to stretch into hole B It is interior.

Further, the hole A and the hole B are coaxially arranged.

Using above-mentioned further scheme advantageous effect single fiber when be easier to stretch into the fiber cores outside fibre cladding Hole B；It can make multiple fiber cores bending degree consistent when multi-fiber, be more uniformly stressed, optical fiber pigtail structure is relatively reliable.
