Adjustable fixed-length optical fiber cutting fixture

Abstract

The invention relates to an adjustable fixed-length optical fiber cutting fixture which comprises a base, wherein the base is provided with a rubber-covered optical cable guide slot for locating a rubber-covered optical cable, the head end of the base is provided with a coating optical fiber slot for a coating optical fiber of the rubber-covered optical cable to penetrate through, and the rubber-covered optical cable guide slot is communicated with the coating optical fiber slot. The cutting fixture also comprises an adjusting sliding block which is in relatively sliding connection with the base, the adjusting sliding block is provided with an adjusting part positioned in the rubber-covered optical cable guide slot, and the adjusting part of the rubber-covered optical cable is provided with a through slot for the coating optical fiber to penetrate through. According to the adjustable fixed-length optical fiber cutting fixture, the adjusting sliding block slides on the base to drive the adjusting part in the rubber-covered wire cable guide slot, so that the reserved length of the coating optical fiber of the rubber-covered wire cable is regulated, and cutting requirements of various lengths of fixed-length optical fibers can be met.

Description

technical field [0001] The invention relates to a fixed-length optical fiber cutting tool, in particular to an adjustable fixed-length optical fiber cutting tool. Background technique [0002] When splicing on site, such as using cold splices or field connectors for optical fiber splicing, it is necessary to strip the optical cable and cut a fixed-length bare fiber at the end according to the requirements of the cold splice or field connector. For example, when splicing a covered optical fiber cable, it is necessary to peel off the sheath layer of the covered optical cable to expose the coated optical fiber, then peel off the coating of a section of the front end of the coated optical fiber to form a bare optical fiber section, and the coated optical fiber formed after stripping The length of the layered optical fiber section and the bare optical fiber section is determined by the specifications of the cold connector or the field connector. Since the cold connectors and fiel...

Problems solved by technology

For example, when splicing a covered optical fiber cable, it is necessary to peel off the sheath layer of the covered optical cable to expose the coated optical fiber, then peel off the coating of a section of the front end of the coated optical fiber to form a bare optical fiber section, and the coated optical fiber formed after stripping The length of the layered optical fiber section and the bare optical fiber section is determined by the specifications of the cold connector or the field connector. Since the cold connectors and field connectors of different manufacturers have different requirements for the length of the coated optical fiber section and the bare optical fiber section, construction personnel It is necessary to be equipped with tooling of various specifications to meet the needs of stripping and cutting of the peeling cable, which brings great inconvenience to the construction. Once the tooling of a certain specification is missing, the construction will not be able to proceed.
