Fujikura 21S Fusion Splicer
The Fujikura 21S active cladding alignment fusion splicer bridges the long standing gap between core alignment and fixed v-groove fusion splicer technology. Moveable v-grooves eliminate splicer errors due to dust and other contaminants. Despite its incredibly small size, this ruggedized, full-featured unit offers unmatched versatility for splicing in the most challenging environments. The innovative transit case and work tray provide multiple options for the best utilization of available work space while the long life battery provides power for up to 200 splice cycles which include application of the splice protection sleeve.
The Fujikura 21S incorporates features typically found only in more expensive models. Removable sheath clamps allow the use of fiber holders if desired. The large 4.7" monitor provides a crystal clear image, even in the brightest sunlight, for evaluating splice quality. The electrode life has been extended to 3,000 splices, minimizing downtime for replacement and stabilization. Software updates are accomplished via the internet allowing users to quickly update their software as new splice programs become available. The fully ruggedized chassis provides for shock, dust and moisture protection while the two camera observation system provides for accurate fiber alignment and loss estimation calculations. The Fujikura 21S is also fully compatible with the FUSEConnect™ line of fusion installable connectors.
Backed by the best service team in the industry, the Fujikura 21S is the ideal splicer to use when portability, ruggedness, versatility and reliability are needed for your splicing application.

Fusion Splicing Process
The process of fusion splicing normally involves using localized heat to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion.
Stripping the Fiber
Stripping is the act of removing the protective polymer coating around optical fiber in preparation for fusion splicing. The splicing process begins by preparing both fiber ends for fusion, which requires that all protective coating is removed or stripped from the ends of each fiber. Fiber optical stripping can be carried out by a special thermal fiber stripper tool that uses hot sulphuric acid or a controlled flow of hot air to remove the coating. There are also mechanical fiber strippers used for stripping fiber which are similar to copper wire strippers. Fiber optical stripping and preparation equipment used in fusion splicing is commercially available through a small number of specialized companies, which usually also designs machines used for fiber optical recoating.
Cleaning the Fiber
The bare fibers are cleaned using alcohol and wipes.
Cleaving the Fiber
A fiber cleaver is then used to cleave the fiber using the score-and-break method so that its endface is perfectly flat and perpendicular to the axis of the fiber. The quality of each fiber end is inspected using a microscope. In fusion splicing, splice loss is a direct function of the angles and quality of the two fiber-end faces. The closer to 90 degrees the cleave angle is the lower optical loss the splice will yield.
Splicing the Fibers
Current fusion splicers are either core or cladding alignment. Using one of these methods the two cleaved fibers are automatically aligned by the fusion splicer in the x,y,z plane, then are fused together. Prior to removing the spliced fiber from the fusion splicer, a proof-test performed to ensure that the splice is strong enough to survive handling, packaging and extended use. The bare fiber area is protected either by recoating or with a splice protector. A splice protector is a heat shrinkable tube with a strength membrane.
