40 Gb/s CSRZFSK signal generation and transmission labeled with ASK in optical packet networks

We proposed and investigated superimposing intensity-modulated labels onto high-speed carrier-suppressed return-to-zero frequency shift keying-modulated payloads in optical label-switching packet networks. The transmission performances of 2.5 Gb/s ASK label on 40 Gb/s CSRZFSK payload is studied for the first time.
