Fiber Optic cable termination is the addition of connectors to each optical fiber in a cable. Plastic optical fiber, being made of an insulating material, does not conduct electricity. This allows it to be used in flammable or explosive environments, and causes it to be immune to electromagnetic interference (EMI) and keeps connected devices electrically isolated. There are two primary. We terminate fiber optic cable two ways - with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers.
