Mid-section of optical cable line
Mid-span access is the process of opening an entry point in the middle of a laid cable to access its fibers. In fiber optic network, it is sometime necessary to splice large fiber count cables to smaller cables at a location other than at the end of the large cable, called mid-span entry. Backbone cables of 144-288 fibers are common and larger ones are becoming more common too. However, some configurations allow for a multiplex data signal where you can have bi-directional communication in a single fiber. This best practices document is a step-by-step guide for end and midspan access of loose tube optical cable, including sheath removal, core preparation, and fiber preparation. 1 This procedure describes installation and handling practices for Corning Cable Systems armored standard single tube (SST) fiber optic cables containing either ribbon, loose fibers, or bundled fibers.
