Fiber Optic Cable Junction Box Termination Connection Method
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. In network cabling, outdoor connections generally use fiber optic cables. When these optical fibers are installed or laid out, a Fiber Termination Box, or FTB, is used to distribute and protect the optical fiber links in FTTH networks. It explains the step-by-step processes, essential tools, and best practices to help technicians achieve low-loss, high-reliability optical connections in.
