[0002] The optical fiber fusion splicing disc is a tool for protecting the fusion node of at least two optical fibers during splicing, and after the fusion of multiple optical fibers in the fusion splicing disc, the remaining optical fibers usually need to be placed in the fusion splicing disc and drawn out from the outlet of the fusion splicing disc.
