1. A method of providing a space active optical cable (SAOC), comprising:
providing a cable comprising one or more optical fibers, said cable having a first end and a second end;
providing a first electrical transceiver on said first end of said cable and a second electrical transceiver on said second end of said cable; and
enclosing at least one of the electrical transceivers in an enclosure that encloses:
one or more light sources, one or more light detectors, and control electronics;
a coupling medium configured to couple light into and out of the one or more optical fibers;
a radio-frequency (RF) modulator and a local oscillator (LO) modulator configured to modulate light generated by the one or more light sources; and
a light processor coupled to the one or more light sources, the RF modulator and the LO modulator and comprising a filter and lock-diode unit configured to generate a heterodyne output light.
