Abstract :
Summary form only given. We report an improved predistorter, which cancels fifth-order (IMD5) as well as third-order (IMD3) intermodulation distortion and yields a composite triple beat (CTB) of -60 dBc. The uncorrected composite second-order distortion (CSO) is -61 dBc. The reduction in CTB (17.5 dB) is 6 dB better than the largest previously reported for an electroabsorption modulator. Low distortion is preserved after fiber amplification and propagation through 13 km of nondispersion-shifted fiber with a transmission-fiber launch power of +13.4 dBm.
