Abstract

A method and system are provided for aligning the optic port of a device having a Free Space Optics (FSO) connector. In a link device with an FSO connector, a controller determines that an optic port alignment procedure is required. A lens is set to an initial wide beam dispersion mode, and a mirror is set to an initial position angle. Note: the lens and mirror may be the FSO connector receive path or transmit path. An optical signal is communicated at a first low baud rate, and the first baud rate communications are optimized by iteratively adjusting the mirror and narrowing the lens focus. Then, an optical signal is communicated at a second baud rate, faster than the first baud rate, and the second baud rate communications are optimized by iteratively adjusting the mirror and narrowing the lens focus.
