Free-space laser- communication links
OmniBeam 4000 provides wireless secure high-speed communications between buildings. The system uses 20-mW lasers operating at 820 nm and silicon avalanche photodiode detectors to provide transmission at 34 to 155 Mbits/s, depending on distance. The 25-lb modules can be connected to networks including E-3, T-3, OC1, Fast Ethernet, 100 BaseVG, FDDI, and ATM 155.
