Can optical fibers be spliced without equipment
Mechanical splicing is a method of connecting two optical fibers without using heat or a fusion machine. There are the two types of fiber optics splicing : fusion splicing and mechanical splicing. Another method of connecting optical fibers is termination or connectorization, which consists of processing the end of a fiber optic bundle so that it can be connected to other fibers or devices through fiber optic. Fiber optic splicing is the process of joining two fiber optic cables together so that light signals can pass with minimal loss or reflection. Termination is the other, more frequent way of linking fibers.
