Fiber Optic Cleaver

:: What is a fiber cleaver?

A fiber cleaver is a tool or device to cut a near perfect fiber end face. Just as with a diamond cutting tool writer of glass, the grinding wheel a machete (knife) makes a very small cut in the fiber, the fiber is then pressed against the cutting force him to break a 90 ° and exhibit a mirror, just as the face end.

:: Why should we divide the fiber optics?

Fiber opticcleaved fusion splicing. Fusion welding is almost always necessary that the tips of fiber show a smooth end face that is perpendicular to the fiber axis.

This is sufficient vertical and flat end face can be achieved through the process of splitting of the fiber. This process of splitting, fragile broken fiber in a controlled manner.

Polishing a tip can result in even higher quality end faces of fiber, but requires more expensive equipment for cleaning and much more processing time, soIt 's very rarely used for fusion welding.

:: Designs Fiber Cleaver

An optical fiber is divided by applying a sufficiently high voltage resistance in the vicinity of a crack surface large enough, then quickly over the cross-section extends the speed of sound.

This idea has many different implementations in various devices business unit. Some acceptable to apply a tension on the fibers, while scratching the surface with avery hard writing instrument, usually a diamond edge.

Other designs to scratch the surface first, and then click Apply tension. Some acceptable to apply a voltage that is uniform throughout the cross section, while others bend the fiber through a narrow beam, producing high tensile stresses on the outside of the curve.

commercial tools for splitting at the same time all the fibers in a ribbon are widely available. This tape helicopters operating on the same principles as a single fibercleavers. The average quality of a cleaver split tape is somewhat interior to that of a single fiber cleaver.

Scribe and break-splitting can be done by hand or with tools ranging from relatively inexpensive tools for automated workbench tools. Any technique or tool is capable of good splits, the trick is consistent time after time.

In general, the less costly approach that requires more skills and training for technicians to do the split.

:: Typesof cleavers

Most modern fiber cleavers are suitable for the division of accuracy of any single common silica fiber, even under severe conditions online. cleaver designs for special applications in research and technology of measuring and manufacturing of optical components available.

:: The importance of the division of quality

The impact to adhere to the quality, the quality of the resulting fusion welding should not be underestimated. Defects in adherence to one of the most commoncauses of geometric distortion resulting in the compound, which are particularly onerous for single-mode fiber.

Much of the variation in connection loss was observed between the different compounds produced using the same parameters is due to splice variation in the quality of division.

There are several ways you can divide the poor quality of the reduction of the mixture. It can affect the performance of image processing routines used to align the fibers. Cracks in the end face canlead to blisters on the town of Junction, which generally requires that the splice be re-created.

:: Fiber Cleaver features:

Most of the high precision cleavers produce a crack deflection angle <0.5 ° in general with a very high reliability and low on-scattering.

A division operation step are now a reality with a machete. Fiber clamping, bending, scratching and share with one action.

Diamond has the highest quality to split and run on10,000 shares. They are also adjustable split fibers with higher tensile strength, for example, fibers coated with titanium.

It 's easy to split a fiber diameter 80um fiber, 125um size possible to divide, and usually difficult to separate the fibers> 200um. To some extent, the difficulty of splitting of these fibers results from the fact that the fiber material is not crystalline. Again, do not produce a torque perpendicular endface. In front, the most commerciallytorsion angle count on choppers available. Endface angle is proportional to the amount of torque.
