A handheld plastic optical fiber end face processing device and processing method

Abstract

The invention relates to a hand-held plastic fiber end face processing apparatus. The hand-held plastic fiber end face processing apparatus comprises a hand-held end housing and an end face processing assembly housing, wherein a micromotor, heating members and a heat conduction member are arranged in the hand-held end housing; the other end of the end face processing assembly housing is detachably provided with a plastic fiber fixing piece; the output end of the micromotor is connected with the heat conduction member; a piece of sand paper is arranged on the heat conduction member; the plastic fiber fixing piece can fix a plastic fiber to be processed; when the micromotor drives the heat conduction member to rotate, the sand paper is driven to polish the plastic fiber end face; when the plastic fiber end face is polished and becomes smooth, the heating members are energized to heat the heat conduction member; the heat conduction member transfers the heat to the plastic fiber; and the plastic fiber is pasted on the heat conduction member for completing thermoplastic moulding. The hand-held plastic fiber end face processing apparatus can realize polishing and thermoplastic moulding functions for the plastic fiber at single-core and double core plastic optical cable end, and can effectively reduce the insertion loss and return loss of a communication plastic optical fiber or cable which is ready to use after cutting.

Description

technical field [0001] The invention belongs to the field of optical fiber production, in particular to a plastic optical fiber processing device, in particular to a hand-held plastic optical fiber end face processing device and a processing method. Background technique [0002] Plastic optical fiber (POF) is an optical fiber with a core layer made of highly transparent polymers such as polymethyl methacrylate (PMMA) and fluorine-containing plastics. Compared with silica optical fiber, plastic optical fiber is light, soft, and more resistant to bending and vibration. At the same time, because of its large core and easy coupling, it does not require very careful end-face treatment like silica optical fiber during use. In plastic optical fibers for lighting, construction personnel often only need to use scissors and sandpaper to simply process the end faces of plastic optical fibers or optical cables. [0003] However, for the end-face treatment of plastic optical fibers or o...

Problems solved by technology

[0003] However, for the end-face treatment of plastic optical fibers or optical cables for communication that require low insertion loss and return loss, the end-face treatment method of plastic optical fibers for lighting is relatively rough, and because plastic optical fibers or optical cables are often cut and used For the brittle plastic optical fiber, only using special scissors to cut the end face does not guarantee that the end face is straight and free of defects. The insertion loss and return loss are often large, which is not conducive to the improvement of communication quality.

[0004] At the same time, the commonly used end-face processing tools are aimed at silica optical fibers, and there is no special tool for plastic optical fiber end-face processing.

Due to the significant difference in the material of plastic optical fiber and quartz optical fiber, the end-face treatment of quartz optical fiber is not suitable for plastic optical fiber, and they are all desktop, with large volume, complex structure and single function, which is not conducive to outdoor construction
