Abstract
A plurality of fiber lasers or amplifiers which share a common pump source. Cost and efficiency improvement of waveguide fiber telecommunications systems are made possible by routing pump laser power through a 1×N coupler to supply pump light to desired combinations of optical fiber lasers or amplifiers. The design is readily adapted to the use of modules, for example laser modules which have a port for receiving pump light and a port for receiving a wavelength selecting module.
