Abstract

An optical distribution architecture is disclosed wherein wavelength stabilized continuous wavelength lasers are centrally positioned in tandem with star couplers to distributed laser power among a plurality of lightguide paths. The laser power apportioned to each such path may then be locally or remotely modulated thereby reducing the number of lasers required to equip a network. Advantageously, lightguide fibres are single mode and polarization maintaining.
