Most modern fiber cleavers are suitable for precision cleaving of all common single silica glass fibers, even under harsh on-side conditions. Special cleaver designs for applications in research, measurement technology and production of optical components are available.the impact of cleave quality on the quality of the resulting fusion splice should not be underestimated. Deficiencies in a cleave are one of the most common causes for geometric deformation in the resulting splice, which are particularly onerous for single mode fiber.much of the variation in splice loss observed between different splices fabricated using the same splice parameters is due to variation in cleave quality.there are several ways in which a poor cleave can reduce the quality of the resulting splice. It can compromise the performance of image processing routines that perform fiber alignment. Cracks in the its end face can lead to a bubbles at the splice joint, which usually requires the splice to be remade.it is easy to cleave an 80um diameter fibre, possible to cleave a 125um diameter fibre, and usually difficult to cleave >200um fibers. To some extent, the difficulty in cleaving these fibres results from the fact that the material of the fiber is not crystalline. Again, torsion will produce a non perpendicular endface. In face, most commercially available angle cleavers rely on torsion. The endface angle is proportional to the amount of torsion.

Here’s how the process works. The Fusion Splicer ends are first fastened into an enclosure in the splicer in order to protect them during the fusing process. Next the ends are stripped of their coating. If an outer jacket is present it is also stripped. The next step involves a tool called a fiber cleaver. A fiber cleaver is used to cut the fibers in a way which leaves the ends of the cables perfectly smooth and flat. If the ends are not absolutely flat then a perfect splice will not occur. After cleaving the ends they are placed into holders in the splicer.now the splicer’s motors align the cable ends together. Then the splicer generates a small spark at the gap between two electrodes. The reason for doing this is that you need to burn off any moisture or dust which is present. Dust or moisture can cause the splicing process to fail. After this step a much larger spark is generated which raises the temperature at the cable ends above the melting point of glass. This fuses the cable ends together. The location of the spark and the amount of electricity it contains are very carefully controlled. This precise control is necessary in order to ensure that the glass fiber and its cladding are not allowed to mix. If they mix together it results in optical loss.

Material of Fiber Cleaver is fused at high temperature. Fused state only melts the contents, it don’t change its shape or composition or characteristics. This is very important because we don’t desire change in shape or characteristics of the fiber cable. If any of them is altered while splicing, data loss will certainly occur, which is undesired.optical fiber cable is a sophisticated cable made from several layer. Slicing should join each layer to the respective layer only of two fiber cables. Especially the core, which carries light needs to be very flat at joint. Curvature can deflect or diffract light beam. Splice loss occurred due to splicing is direct effect of alignment. Using special type of ofc stripper and cutter, ends are cut carefully. Flatness is observed by microscope or zooming lenses. They are joint end to end and put in fusion slicer. Slicer joins them quickly. The joint is allowed to get cool and firm. Splice protector is applied on the joint.fusion splicing needs to be very accurate and precise. If there is any error in splicing, light will scatter or reflect and data loss occurs. Two ofcs are connected end to end and fused to join. Fusion slicer uses a source of heat such as tungsten filament, light amplification by simulated emission of radiation (laser) beam, gas flame or an electric arc.

Talking about splicing fiber optic cable, you will find two different types of splicing processes. Fusion splice will be the first type and the second one will be mechanical splicing. In this article, we are going to talk about fusion splicing since this is the most recommended type due to the less risk of insertion. Here are some tips in splicing your cable by using this certain method.you have to notice first that fusion splicing is generally a bond of two or more optical fiber that joined together permanently by welding. You need to provide splice cleaver if you want to have less problems of light loss or reflection. Making such a poor spice causes the ends of the fiber could not melt together properly, and surely it could cause problems.to begin splicing your cable, you can start to prepare the fiber first. Strip all the coatings, tubes, as well as jackets of your cable and make sure that you have only bare fiber left. Clean all of the filing gel from the fiber by using gel cleaner. Make sure that you are cleaning it well since clean environment will be great to support better connection.

Today, Power Meter manufacturer usually use laser or electric arc. Gas flame can leave traces of fuel or combustion bi-products, which may alter composition of ofc. Laser and electric arc are clean sources of heat. Laser slicer is preferred because it can operate on battery and quickly slice ofcs. Slicers can be programmed to quickly slicer similar type of ofcs. Portable models usually use laser as heat source. They quickly heat and splice ofcs in no time.certain advanced slicers have microscope integrated. Which ensures that there would be no wrong alignment or curvature? With tft lcd screen, it is possible to visualize slicing process in 2 dimensions, which ensures it will go in right way. Further, they can check for final slicing and log the result for future purpose. Computer connectivity makes it possible to record progress and log history.fusion slicers are extensively used by telecommunication companies. Optical fiber network proves to be very reliable, efficient and low power communication media. Data is secured and loss is negligible. Hence more and more telecommunication companies are expanding their network by ofcs. New type of ultra fast internet connection is available with ofcs only. Mobile towers are preferably connected by ofcs, as microwave links may get interrupted.

You can cleave the fiber. You need to provide a good cleaver to get an excellent splice. You can align the fibers either automatically or manually when you fusing the fibers together. It will be depended on the type of your machine. An electrical arc usually will melt the fibers together and it will create permanent welding for the two ends of the fibers.third, you can take heat shrink tubing to protect the fiber. It will be perfect to keep the optical fiber of your cable safe from any elements that might create breakage.now your cable has been spliced successfully. In order to get maximum splicing result, it will be better for you to provide some supporting tools in great quality. Therefore, you will not feel disappointed with the splicing result of the cable.other designs scratch the surface first, and then apply tensile stress. Some cleavers apply a tensile stress that is uniform across the cross section while others bend the fiber through a tight radius, producing high tensile stresses on the outside of the bend.commercial instruments for simultaneously cleaving all the fibers in a ribbon are also widely available. These ribbon cleavers operate on the same principles as single fiber cleavers. The average cleave quality of a ribbon cleaver is somewhat interior to that of a single fiber cleaver.scribe-and-break cleaving can be done by hand or by tools that range from relatively inexpensive hand tools to elaborate automated bench tools. Any technique or tools is capable of good cleaves; the trick is consistent finishes time and time again.

A fiber optic cleaver is a piece of tool or equipment to make an almost perfect fiber end face cut. Just like using a diamond scribe tool when cutting glass, a cleaver’s cutting wheel (blade) makes a very tiny cut on the fiber first, then the fiber is pressed against the little cut to force it to break at 90° angle and expose a mirror like end face.optical fiber needs to be cleaved for fusion splicing. Fusion splicing nearly always requires that the fiber tips exhibit a smooth end face that is perpendicular to the fiber axis.this sufficiently perpendicular and planar end face can be achieved via the fiber cleaving process. In this cleaving process, the brittle glass fiber is fractured in a controlled manner.polishing a tip can result in even higher quality fiber end faces, but polishing requires more expensive equipment and more processing time, so it is very rarely employed for fusion splicing.an optical fiber is cleaved by applying a sufficient high tensile stress in the vicinity of a sufficiently large surface crack, which then rapidly expands across the cross section at the sonic velocity.this idea has many different practical implementations in a variety of commercial cleaving equipment. Some cleavers apply a tensile stress to the fiber while scratching the its surface with a very hard scribing tool, usually a diamond edge.

After the Fusion Splicer is fused together the splicer injects light through the cladding on one side of the splice and measures the light leaking from the cladding on the other side. This measurement is taken to ascertain the quantity of splice loss. Splice loss is the amount of optical power lost at the splice point as a result of the splicing process. A splice loss of less than 0.1db is routine when using a fusion splicer.as a general rule the fiber ends are inspected before and after the splicing process. This is done using the splicer display screen which provides a magnified view of the splice area.fusion splicers are used extensively in the telecommunications industry as well as the computer networking industry. They are invaluable in insuring that fiber based network downtime is kept to a minimum.splicing fiber optic cables is definitely not like splicing metal cables together. It’s a very precise process best achieved using a fusion splicer. A fusion splicer connects two fiber optic cables together by melting or fusing them. In order to minimize potential optical loss or signal loss, optical fibers must be joined together absolutely perfectly.hence fusion slicer performs a lot to join ofcs for the network.
