Abstract

Free Space Optical (FSO) communications systems require robust pointing, acquisition, and tracking approaches to close and maintain links due to inherent beam directionality and susceptibility to atmospheric effects. Typically, the incoming beam must be split into two paths to align with two spatially separated detectors, one for beam position sensing and the other for data reception. We present a dual-purpose, in-line position sensor and data receiver using a 7-fiber hexagonally-packed fiber bundle. We present data collected across a 30 km terrestrial FSO link operating at 10 Gbit/sline rate with an average 95% link availability and compare these results to outputs from our link budget model.
