50/125 Launch Optical Fiber

P/N: BF06864

These multimode step-index launch optical fibers are designed with low 0.22

numerical aperture — an extra low 0.15 NA is also available. These configurations

can handle peak power delivery approaching 1GW/cm2. The coating offers easy

mechanical stripping and is compatible with either carbon or PYROCOAT® polyimide

coatings, or both, when various combinations of hermeticity and/or high temperature

resistance are needed. Launch fibers can also be metalized for hermetic sealing

into opto-electronic devices.
