“…In this paper, we introduce a novel beam tracking architecture which utilizes a hexagonally packed 7-fiber bundle to perform both the position sensing (outer fibers -multimode) and data collection (center fibersingle mode), resulting in a robust, in-line tracking approach [4]. This technology has been integrated into a monostatic, single mode coupled FSOC payload developed by JHU/APL.…”

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 hexagonallypacked fiber bundle. We present data collected across a 30 km terrestrial FSO link op erating at 10 Gbit/s line rate with an average 95% link availability, and compare these results to outputs from our link budget model.
