研究目的
Demonstrating error-free 100-Gb/s optical packet switching with low power consumption using a combination of a label processor and 8 × 8 broadcast-and-select optical switch.
研究成果
Error-free operation for 100-Gb/s burst optical packets was demonstrated with a significant reduction in power consumption. The total power consumption of the 8 × 8 optical packet switch is estimated to be as low as 27.3 W (3.4 W/100-Gb/s port). The technology shows promise for future optical packet switched networks.
研究不足
The scalability of the port count is limited due to the power-splitting intrinsic loss in the B&S switch. The study focuses on 100-Gb/s packets, and further research is needed for higher data rates.
1：Experimental Design and Method Selection:
The study employs a combination of a label processor and an 8 × 8 broadcast-and-select optical switch for optical packet switching. The label processor includes an optical-trigger-pulse generator and an optoelectronic serial-to-parallel converter. The optical switch is based on electro-absorption-modulators.
2：Sample Selection and Data Sources:
The experiment uses 100-Gb/s input optical packets generated by four 25-Gb/s tunable transmitters.
3：List of Experimental Equipment and Materials:
The setup includes a label processor, 8 × 8 B&S optical switch, tunable transmitters, WDM coupler, burst-mode EDFA, and a 25-Gb/s burst-mode avalanche photodiode and trans-impedance amplifier.
4：Experimental Procedures and Operational Workflow:
The packets are fed into the optical switch, selectively switched to output ports, amplified, and detected for error measurement.
5：Data Analysis Methods:
Error measurements are conducted to verify error-free operation.
