OPTICAL GENERATION OF 43 GBIT/S PHASE-SHAPED BINARY TRANSMISSION FORMAT FROM DPSK SIGNAL USING 50 GHZ PERIODIC OPTICAL FILTER
25 September 2005
A novel method to optically generate PSBT format at 43 Gbit/s is proposed hereafter. Performance have been compared with NRZ format showing reduced OSNR penalty by 0.7 and 1.3 dB for 4.10-3 (FEC limit) and 10-5 BER, respectively.
