Collimator Focus Adjustment for Free Space Optics System Using Single-mode Optical Fibers

摘要

This paper presents a method for adjusting a free space optics (FSO) system that links two single-mode optical fibers (SMFs) using collimators. It operates as if the two SMFs were seamlessly connected without the need for any photoelectric devices. Collimator focusing as well as axis alignment is critical for low loss transmission and is performed using an opto-mechatronic system in the proposed method.
