Heat-shrink and mechanical crimp connectors are the most common methods. When splicing inside a building, you can use a splice center when rack or wall space is available. While fiber splicing has been performed for several years, the technology is quite dynamic, with the introduction of faster, simpler, and less expensive splicing equipment and consumables. This is especially true for multimode fibers in the commercial building and campus markets. If fusion is your chosen method, think about attenuation or loss performance when selecting a splicer.
Manufacturers generally list field loss and laboratory loss.
Typical loss in the field indicates expected performance under actual field conditions, allowing for variations in climate, cleanliness, cleaving and operator training. The laboratory specification indicates best-case performance under ideal conditions. Specification sheets always reference this value unless otherwise stated. An installer faces a capital investment or rental charge for fusion splicers, depending on the type of machine. The mechanical splice requires a nominal charge initially.
