A bi-directional optical link, comprising: a light source for transmitting light at a first wavelength; a photodetector in substantially linear arrangement with the light source for detection of light of a second wavelength; and an optical fiber for carrying light of the second wavelength to the photodetector and for carrying light of the first wavelength from the light source, the optical fiber in substantially linear arrangement with the photodetector and the light source.
