Abstract: In optical communication systems, 980 nm high-power laser modules are applied for long-distance communication amplifiers. Since the mode field of the 980 nm laser diodes is different from ...

Abstract: The GI (graded-index) POFs (Plastic optical fibers), which has been proven to reach distances as long as 1 km at 1.25 Gb/s has a relatively low numerical aperture . Therefore, the efficient ...
