Fusion splicing provides a low-loss, highly reliable connection by melting and fusing fiber ends, making it ideal for long-haul. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. What is Fiber Optic Splicing and Why is it Needed? – #1.
