Fiber stubs are used throughout telecommunications, from TOSA/ROSA components to field installable connectors.

The ability to precisely generate optical grade cleaves at defined positions from the ceramic ferrules is an advantage of laser processing. As the tip of the cleaved fiber stubs are often inserted into polymeric v-grooves for alignment, the ability to deliberately round the edges is often necessary. Laser cleaved fiber stubs can be created with fiber protrusion of virtually any length from just a few 100 microns, to suit the needs of your application.

The optical quality of laser cleaved fiber stubs is unsurpassed, providing a highly reproducible cleave angle and an exceptionally low-scatter surface for enhanced performance. The laser cleave process also controls the amount of corner rounding to aid insertion and optimize core contact. As a non-contact process, laser cleaving minimizes the risk of mechanical damage, moreover, the laser cleave can be accurately positioned with reference to the ferrule, or other mechanical references for excellent length reproducibility. 

Moreover, the reliability and reproducibility of the process, allows the whole manufacturing sequence to be optimized, with the laser cleaving process, which produces the final optical quality end, carried out as the final step in the assembly.
