PMD is one of the main factors to signal distortion in high bit rate optical fiber communication systems. A novel PMD compensation scheme based on FPGA using DPSO algorithm is proposed. We experimentally demonstrate stable polarization compensation for 43Gbit/s RZ-DQPSK transmission over 1200km with endless polarization scrambling. The PMD compensation shows excellent performance for signals in case...
A new adaptive polarization mode dispersion PMD compensation method in 80 Gbit/s optical communication is proposed. Through the control of DSP, the dithering particle swarm optimization (PSO) algorithm is used to extract the best degree of polarization (DOP), then the DOP is used to compensate three stage PMD of optical fiber.
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...
Polarization mode dispersion (PMD) causes time and channel dependent pulse distortions in high-speed optical fiber communication systems and limits their transmission capacity. We designed a low power-consume DSP-based integrated control system using the particle swarm optimization (PSO) algorithm to complete first-order PMD and second-order PMD compensation. The experiment results showed that the...
This paper demonstrates a universal digital signal processing (DSP) application for adaptive polarization mode compensation (PMD) compensation in optical fiber communication systems. Because PMD possesses the time-varying and statistical properties, especially in high-speed optical fiber communication systems, to establish an effective logic control compensator is important and challenging. We designed...
We gave an analysis about the wavelength-division multiplexing isolation filter consisted of two concatenated long period fiber grating (LPFG), and the numerical simulation was performed by transfer matrix method. The key factors in design this high performance filter was proposed. Based on the key factors, flat transmission spectrum of the LPFG in range of 80nm was obtained by the particle swarm...
