Simultaneous amplification of 20 channels in a multiwavelength distribution system

Simultaneous amplification of a 20-channel multiwavelength signal using a traveling-wave semiconductor optical amplifier is discussed. The channels occupied a band 34 nm wide centered at 1.54 mu m, and 6-8-dB net gains were obtained. Bit-error-rate measurements at 1 Gb/s showed small receiver penalties due to amplifier noise and interchannel crosstalk.<
