Abstract
An arrangement for effectively fusing together two optical fibers. Many fibers currently have a carbon-based coating applied to the bare fiber, with the coating being surrounded by a plastic jacket. It has been difficult to fuse the two fibers together due to the coating. The present invention provides an effective method for removing the coating using a rapid and high temperature electric discharge. The removal of the coating allows a better connection of the two fibers with the connection having a low transmission loss.
