Optical fiber due to its superior transmission capacity forms the foundation of today's optical
fiber network. Generally during optical link construction, initially, optical fiber cables are joined
into longer fiber links by end-to-end splicing of similar type optical fibers cable, and the optical
fiber cable was stored in the form of coils (20-50 meters) at several locations (manholes/hand
holes/chambers) to ease the accessibility of fibers for branching/dropping for future needs. It is
sometimes necessary to splice large fiber count cables to smaller cables at a location other
than at the end of the larger cable. Rather than cutting the cable and splicing all the fibers, a
mid-span entry can be used to access only the fibers required for splicing to the smaller
cable(s). Fibers are dropped off the main cable mid-span to connect with other cables/drop
cables and the remaining fibers continue for service beyond the drop-off location. This type of
fiber access is called cable mid-span access.
