Fiber transmission of optical differential 8- level phase- shift keying ( OD8PSK) signals is demonstrated for the first time. Co- polarized 8 WDM channels of 10 Giga- symbol/ s or 30 Gb/ s return- to- zero ( RZ) OD8PSK signals with a channel spacing of 50 GHz were transmitted over 320 km of standard single mode fiber ( SSMF) with an EDFA spacing of 80 km. The BER of the worst WDM channel after transmission of 320 km was 2.3 x 10(-5).
