We report an experiment of de-multiplexing automatically in a polarization division multiplexing system using a DSP based de-multiplexer. The searching algorithm was a modified Particle Swarm Optimization. We successfully demonstrated the de-multiplexing scheme both in a 20-Gb/s PolMux-NRZ-OOK system and a 40-Gb/s PolMux-RZ-DQPSK system.
Polarization mode dispersion (PMD) monitoring can be used for polarization stabilization and PMD compensation. A scheme of digital signal processor (DSP) based high precision real-time inline PMD monitoring is designed and implemented. Experiment was made and demonstrated significant improvement. The response time is 1 μs and the accurate degree is 1%.
In high-speed optical transmission communication systems PMD compensation is crucial and it is challenging to establish an efficient compensator. We demonstrate an optical polarization mode compensation (PMC) system with logical controlling unit based on DSP and CPLD platform. The PMD compensation platform we designed implements with some high-speed control components which shorten the compensation...
This paper describes implementation of a DSP for adaptive PMD compensation in 80 Gbits/s DQPSK optical fiber communication systems. Using dithering particle swarm optimization (DPSO) algorithm, the searching process and tracking process could be completed in 10 ms and 1 ms respectively.
This paper describes implementation of a universal digital signal processing (DSP) for adaptive polarization mode compensation (PMD) in optical fiber communication systems. PMD is one of the most difficult issues in implementing high-speed optical communication systems with bit rates of 10 Gb/s or higher. Because PMD possesses the time-varying and statistical properties, to establish an effective...
