Fujikura 45S Fusion Splicer Standard Kit

SKU: NPNB-S018318
Various lead times may apply to this product. Please contact us for more details.


Fujikura 45S Active Cladding Alignment Fusion Splicer

The Fujikura 45S is is changing the way people splice fiber in small to mid-fiber count applications. The 45S splicer debuts a landmark improvement to the fusion splicing process with the ability to prepare and load both fibers simultaneously. The hand-held fiber coating stripper, the SS-05, is capable of stripping two 250 μm coated fibers in the same pass, along with the CT-16A cleaver adapter plate which can likewise accommodate two bare fibers for cleaving.

After preparation, the 45S patented sheath clamps enable loading both fibers simultaneously into the splicer with one fiber in each hand. The user can press down on the sheath clamp base to close it while positioning the fiber in the v-grooves. This enables onehanded operation.


  • Simultaneous fiber preparation with newly patented sheath clamp design
  • Sheath clamps automatically opened with the wind protector
  • Automatic fiber placement correction
  • Active Fusion Control for arc optimization with every splice
  • Active Blade Management for cleave quality monitoring and correction
  • Easy-access battery, screen position adjustments, and ergonomic adaptations
  • Fully ruggedized for shock, moisture and dust resistance


Additional Information

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.
