One of the major benefits of fiber splicing is a lower insertion loss when compared to terminating a connector. There are two ways to splice fiber, mechanical splice, or fusion splice.
Mechanical splicing doesn’t require any expensive equipment. This splicing method is a junction of 2 or more fiber to hold them in place once it has been aligned. The cover can be a snap on or contain adhesive to permanently hold the splice. Now this doesn’t mean that the fiber is bonded but just precisely aligned so that light can pass from one fiber to the other. Mechanical splicing is a fast and quick solution to repair any damage fiber. The only downfall is that mechanical splicing has a high insertion loss when compared to fusion splicing
Fusion Splicing will require a fusion splicer. These splicing equipment can be expensive. The fusion method will align two ends of a fiber and permanently bond the end using an electric arc. This is the absolute best method for the lowest insertion loss and low back reflection.
