SPI Diamond Optical Fiber Cleaving Tool

The indispensable tool for the joining of optical fiber

The use of glass fibers in optical communication systems brings with it the need to make optic fiber connections. These fibers typically have diameters of roughly 100 - 200ľm and must be joined via precisely matching flat end surfaces. One approach to achieving such surfaces is by polishing roughly cut ends, but this is time consuming and inconvenient if not impossible in the field. Another method used more often is the "scratch and pull" technique. A scratch is made on the side of the optic fiber with a sharp diamond knife and the fiber is then pulled to the breaking point. Under the right conditions, a clean, optically flat break occurs, with surfaces perpendicular to the fiber axis.

SPI Supplies offers diamond cleaving knives designed to produce clean scratches on optic fiber surfaces and we offer this handy hand-held precision instrument to end users worldwide.

Specifications of the blade:
The knife "blade" has a width of 14 mm and 0.25 mm diameter. The blade has a 60° included angle, with the cutting edge on the center line of the holder, but at a 45° angle to the long axis.
