Fiber connector 150 includes pull handle 151, optical fiber head 152 and pull rod 153.Specifically, when needing to extract fiber connector,
Pull handle 151 can be pulled along the direction opposite with optical fiber head 152, drive pull rod 153 to move, and then fiber connector is extracted.Figure
4b is the top view of pull-ear-type fiber connector in the utility model embodiment two；Fig. 4 c is drawn in the utility model embodiment two
The structural schematic diagram of shank type fiber connector.Fig. 4 a, Fig. 4 b, Fig. 4 c show the knot of pull-ear-type fiber connector from all directions
Structure.It should be noted that Fig. 4 a, Fig. 4 b, Fig. 4 c only schematically illustrate pull-ear-type light there are many pull-ear-type fiber connectors
The structure of fine connector, is not specifically limited it.
The utility model embodiment embodies connection type of the optical fiber in modular cartridge on the basis of above scheme, leads to
It crosses and PLC splitter is fixed on inside modular cartridge, and input terminal, in the panel hole side, output end is far from panel hole one
Side curls up the input optical fibre of the input terminal of PLC splitter one week in modular cartridge counterclockwise, by being fixed on input face plate hole
Interior casing extends to outside modular cartridge, and the output optical fibre of the output end of PLC splitter is curled up in modular cartridge one week clockwise
Half, it is extended to outside modular cartridge by the casing being fixed in output face plate hole, so that the connection of optical fiber has certain resiliency,
It prevents in production process, optical fiber is pulled to cause the too small increase loss of disconnected fine or bending radius.And fiber connector is arranged
For pull-ear-type fiber connector, significantly more efficient plug when solving the problems, such as to need to be transformed route is inconvenient.
