The linewidth requirement for CPFSK differential detection is evaluated. CPFSK modulation of DFB-LD is confirmed from the spectrum correlation between an output spectrum and calculated results. In a 1.55 μm 400 Mbit/s transmission experiment using a 290 km pure-silica-core fibre, average received optical power at a 10−9 bit error rate is −49.9 dBm.
