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.
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 laserCleave process also control the amount of corner rounding to aid insertion and optimise 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 reference for excellent length reproducibility.
Laser cleaved fiber stubs can be created with fiber protrusion of virtually any lenght from just a few 100 microns, to suit the needs of your application.
Moreover, the reliability and reproducibility or the process, together with the ability to process parts already assembled into fixtures or ferrules, allows the whole manufacturing sequence to be optimised, with the laser cleaving process, which produces the final optical quality end, carried out as the final step in the assembly.
