However, they also use mechanical splicing for shorter, local cable runs. Many companies now invest fusion for networks, especially for long haul single-mode networks. The more precise you need the alignment (better alignment results in lower loss) the more you pay for the machine. While the cost per splice for fusion splicing is lower ($0.50-$1.50 each), the initial investment is much higher ($15,000-$50,000 depending on the accuracy and features of the fusion splicing machine being purchased). However, with fusion splicing, the fibers generally have a loss of 0.1dB and the fiber splices are usually stronger.Ĭost：mechanical splicing has a low initial investment ($1,000-$2,000) but costs more per splice ($12-$40 each). Performance: with mechanical splicing, the fibers usually have loss of 0.3dB. However, fusion splicing is more skilled and need more time to be finished. Time Requested: mechanical splicing is fast and effective, which is suitable for some emergency situations. Mechanical splicing-the completed mechanical splice provides its own protection for the splice. All splices shall use the fusion technique. The index matching gel inside the mechanical splice apparatus will help couple the light from one fiber end to the other.įusion splicing-using heat shrink tubing, silicone gel and/or mechanical crimp protectors will keep the splice protected from outside elements and breakage. All optical fibers shall be spliced to provide continuous runs. Simply position the fiber ends together inside the mechanical splice unit. Mechanical splicing does not need heating. Once properly aligned the fusion splicer unit then uses an electrical arc to melt the fibers, permanently welding the two fiber ends together. Step four: after cleaning the fiber, the connecting step starts.įor fusion splicing, fusing fiber contains alignment and heating.As to mechanical, the cleaving process is identical to the cleaving for fusion splicing but the cleave precision is not as critical. The cleaved end for fusion splicing must be mirror-smooth and perpendicular to the fiber axis to obtain a proper splice.
Latest advancements in this type of connector have improved yield, and little or no training is required. Step two: cleave the fiber with a fiber optic cleaver. No-epoxy/no-polish connectors (prepolished connectors with mechanical splice).This style of fiber-optic termination is the fastest and easiest to install, making it a popular choice for anyone who needs to terminate optical fiber in the field.Step one: strip the protective coatings, jackets, tubes, strength members, etc.Process: The first three steps of mechanical splicing and fusion splicing before connecting the fibers ends are generally the same.
