Optical Fibre Cleaver

A cleaver is a tool used to cleave optical fibres prior to splicing.  Optical fibres should have a plain and clear surface when they are cut.  The cut should be perpendicular to the longitudinal axis of the fibre.  This is essential to avoid loss of light or distortion.    The cleaving tool is used to cleave the fibre. 
Cleaving Tools generally use diamond tips and blades to cleave the fibres.
Certain mechanical cleaving tools use a diamond blade to make a wedge in the fibre and the twist the fibre to produce a clean break.  The cleave angle should be perfectly 90 degrees. 
The blade in the cleaver may have to be replaced after a certain number of splices.  Most manufacturers provide replacement blades. 
The cleave made is examined by the splicing machine prior to fusion
