Abstract
Means (30) for continuous waveband tuning of a laser (2) are disclosed, along with means (34) for relating such tuning to a reference wavelength, by maintaining any desired offset (35) from that reference wavelength. Multichannel fiber optics communi-cations networks employing the above means (30) are disclosed, said networks being self organizing in terms of the wavelengths of their channels.
