Optical Fiber Cable Melting Technology
Hot Melt connectors use a “hot melt” adhesive preloaded into the connector. The termination process involves heating up the connector until the adhesive becomes a liquid, then inserting the stripped and cleaned fiber. Fiber Strippers: Fiber strippers are used to remove the protective coating from the fiber optic cables to expose the glass fiber core. This is important to ensure that the fibers are aligned. Caution: The Hot Melt oven operates at twice the temperature of the epoxy curing oven -245 - 270 degrees C. It can cause burns if the metal parts are touched while hot. Be extremely careful with the oven! NOTE: Paper catches fire at 451 degrees F, so don't rest anything. These are the "outside vapor deposition" (OVD) process developed by Coming Glass Works and the "vertical axial deposition" (VAD) version developed by a consortium of Japanese cable makers and Nippon Telephone and Telegraph Corporation. From the first works dealing with the optimization of optical fibres transmission characteristics to accommodate long distance data transmission, realized by Charles Kao (Nobel Prize of Physics in 2009), until the.
