Abstract
The scanning free space optical broadband access network uses LASERs to carry high-speed data streams between a central location and a number of subscribers served from that location. High-speed digital data modulates the LASERs in both directions, allowing a virtual MAN to be created. A few dozen subscribers share a single virtual pipe with several hundred Mbps band-width available. Beam scanning techniques at a central hub permit a single LASER and optical assembly to serve many customers.
