Paper Abstract

The classical scheme of OBS (Optical Burst Switching) optical wavelength channels uses ITU-T’s DWDM (Dense Wavelength Divided Multiplex) standard wavelength at 1550nm band. BHPs (Burst Header Packet) over control optical wavelength channel and BPs (Burst Packet) over burst packets optical wavelength channels all choose this band. A novel scheme of OBS control optical wavelength channel selects 1310nm wavelength as the control optical wavelength channel, and the other channels are the same with the classical scheme. The key design is to choose broadband 1310/1550 wavelength divided multiplexer and demultiplexer, the band range is from 1270 to 1350nm at 1310nm band, from 1520 to 1610nm at 1550nm band, also its isolation is more than 30dB. The novel scheme has advantages of saving resource of DWDM wavelength channels and reducing cost of OBS system based on assuring the capability and quality of OBS system, comparing with the classical scheme.
