We demonstrate a novel in-line chromatic dispersion monitoring scheme for 100 Gbit/s RZ-DQPSK signal based on delay tap sampling and asymmetry ratio evaluation. This scheme can differentiate positive and negative residual chromatic dispersion.
All-optical packet switching with all optical heading processing using one and two Fabry-Perot laser diodes are studied numerically. Both the header and data rates are at 10 Gb/s.
For efficient utilization of bandwidth in optical packet switching, the guard time Tg between packets should only be a small fraction of the packet transmission time Td. Since the guard time Tg of existing packet switching approaches must be larger than the reconfiguration time Tsw of optical switches, this imposes a stringent demand on the switch reconfiguration time Tsw as the transmission...
