摘要:
Improvement of BER owing to nonlinear transformation of input noise distribution by all-optical interferometric wavelength converters (TWCs) is investigated. II is demonstrated experimentally that a 5dB penalty arising from EDFA-induced noise can be reduced to 1dB by employing IWCs. Measured noise distributions for the input and the converted output signals are given.
