4x4 optical packet switching of asynchronous burst optical packets with a prototype, 4x4 label processing and...

Area of Science:

• Optical networking
• Telecommunications engineering
• High-speed data transmission

Background:

• Asynchronous burst variable-length optical packets present challenges for efficient network management.
• Existing optical packet switching systems often struggle with high data rates and complex routing.
• The demand for faster and more reliable optical communication networks is increasing.

Purpose of the Study:

• To develop and demonstrate a prototype 4x4 label processing and switching subsystem.
• To evaluate the performance of the subsystem for 10-Gb/s asynchronous burst variable-length optical packets.
• To assess the power consumption and latency of the developed optical packet switching system.

Main Methods:

• Implementation of a 4x4 prototype subsystem for optical packet switching.
• Testing with 10-Gb/s asynchronous burst variable-length optical packets.
• Measurement of bit error rate (BER), power consumption, and latency.

Main Results:

• Achieved error-free operation with a bit error rate (BER) below 10^-12.
• Demonstrated simultaneous switching for all 16 possible input/output combinations.
• Recorded a total power consumption of 83 W (including fan power) and a latency of 300 ns.

Conclusions:

• The prototype 4x4 subsystem successfully enables high-speed, error-free optical packet switching.
• The system demonstrates efficient label processing and switching for complex network traffic.
• The low latency and power consumption indicate the potential for practical deployment in future optical networks.
