We estimated the BER performance of spectrum-sliced WDM access influenced by adjacent crosstalk numerically and experimentally. The BER performance was improved as the spectral width was widened, while it was degraded by the crosstalk as the spectral width approached the channel spacing. We derived the optimum spectral width as 14 GHz at a channel spacing of 25 GHz and a bit rate of 155 Mbps, and the BER was estimated to be less than 10/sup -15/ between 12 to 16 GHz. The transmission performance was also measured by experiments using 15-GHz wide, 25-GHz channel-spaced, 155-Mbps /spl times/ 32-channel transmissions through 50-km of DSF, and showed good agreement with the calculated results.
