The intermediate node architecture of the mesh network can be the same with current wavelength switching Wave- length Division Multiplexing (WDM) net- works, and thus can reuse existing deployed infrastructure. We employ a novel Optical Time Slot Interchange (OTSI) at the source nodes for the first time to mitigate the burst conten- tion and to increase the bandwidth utilization. Time- and wavelength-domain reuse in the OTSI significantly saves optical components and red- uces blocking probability.展开更多

The modulation depth of downstream differential phase-shift keying is properly reduced to facilitate phase remodulation and Rayleigh noise mitigation. For both downstream and upstream 10 Gb/s signals, error-free transmission via a 20 km single-mode fiber is demonstrated without dispersion compensation operation.展开更多
