Abstract
Disclosed are methods, systems and non-transitory computer readable memory for free-space optical (FSO) communications. For instance, a communications network may include FSO optical transceiver terminals located at remote electrically unpowered locations within the communications network. A remote unpowered FSO terminal located at a far-end location receives necessary optical power from a powered base station location (near-end) required for all optical amplification functions for NRZ or RZ format signals within the spectral range of 900 nm to 1480 nm as well as an Ultra Short Pulsed Laser (USPL) centered at 1560 nm at the far-end location. A transmitting node transmits an optical signal identified as a pump signal to a remote location over a free space medium, such as the atmosphere, where the remote location does not have available electrical power for operation of electro-optic components required for transmission and retransmission functions.
