A downstream transmission using a wavelength‐locked Fabry–Perot laser diode (FP‐LD) with a spectrally sliced FP‐LD as a WDM optical source is presented and experimentally demonstrated for application to a WDM passive optical network (PON) link. A side‐mode suppression ratio (SMSR) of better than 40 dB is achieved by using an amplified and spectrally sliced FP‐LD as an external‐injection optical source. As a result, a downstream transmission of 622 Mb/s using a wavelength‐locked FP‐LD is successfully performed over 25 km. We can verify the feasibility of this method by its characteristics of simplicity, operational ease, and wavelength tunability. © 2004 Wiley Periodicals, Inc.
