Abstract of the Disclosure An optical multiplexer/demultiplexer using wavelength division multiplexing comprises a fibre optic port for connection to an optical transmission fibre, a dispersive diffraction element, and an array of alternate light sources and light detectors. One or more focussing and collimating elements direct predetermined spectral components diffracted by the diffraction element from the light sources to the fibre optic port and from the fibre optic port to the light detectors, thereby allowing simultaneous reception and transmission of optical signals in a single unit.
