Some methods use a chemical to speed up the process but it's sometimes too fast for installers to use easily. Heat-cured epoxy and Hot Melt connectors have one big advantage over anaerobic connectors; there is a small bead of cured epoxy on the end of the connector that makes. Fiber optic connector manufacturers have been working for over 30 years to make terminating optical fiber easier, faster and cheaper, and they have done a really good job. But perhaps they have been overselling the simplicity of fiber optic termination. It explains the step-by-step processes, essential tools, and best practices to help technicians achieve low-loss, high-reliability optical connections in. Fiber optic splicing is the art and science of joining two separate optical fibers to create a continuous light path. This article. Fiber preparation for splicing and termination requires removal of a section of the protective cable elements, such as the jacket, armor (if present), and buffer tubes. My process after striping the cables is usually: Continue from step 3 12 times, until one set is complete.
