Abstract: Four-wave mixing of transmitted signals in a lightwave transmission system is reduced by (1) grouping the signals in pairs of adjacent frequencies, (2) increasing the frequency of every other pair by a fixed amount, and (3) decreasing the frequency of the remaining pairs by the same fixed amount, where the fixed amount is less than the permitted variation of the ITU grid.

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 1xN 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.
