Description

Clamping device of optical fiber jumper wire

Technical Field

The utility model belongs to the technical field of clamping devices, and particularly relates to a clamping device for an optical fiber jumper.

Background

The optical fiber jumper (also called optical fiber connector) means that connector plugs are arranged at two ends of an optical cable and are used for realizing movable connection of an optical path; one end of the optical fiber is provided with a plug, and the optical fiber is called a tail fiber. Optical Fiber Patch cords (Optical Fiber Patch Cord/Cable) are similar to coaxial Cable, except that there is no mesh shielding. The center is the glass core through which the light propagates. In the multimode optical fiber, the core diameter is 50 to 65 μm, and approximately corresponds to the thickness of human hair. And the diameter of the single-mode optical fiber core is 8-10 μm. The core is surrounded by a glass envelope having a lower refractive index than the core to retain the optical fiber within the core. Further on the outside is a thin plastic outer sleeve to protect the envelope.

With the connector mounted on one fiber end face, return loss is inevitable due to reflection from the light source. The light loss seriously damages the laser light source and interrupts the transmission signal. To allow for better contact between the end faces of the two optical fibers, the ferrule end faces of the optical fiber jumpers are typically ground to different configurations.

At present, when the optical fiber jumper is ground completely, because the connectors at the two ends of the optical fiber jumper are mostly cylindrical and square, and the size of the connector in the same shape is different, the existing clamping device is difficult to adapt to various types of connectors well.
