We propose a bidirectional reflective semiconductor optical amplifier (RSOA) based wavelength-division-multiplexing passive optical network (WDM-PON) utilizing a differential phase shift keying (DPSK) signal for down-link and an on-off keying (OOK) signal re-modulated for up-link with high extinction-ratio in both directions. A 20 km range colorless WDM-PON without dispersion compensation was demonstrated...
The growth of bandwidth demand due to increasing number of users and available services, led to development of optical networks. In order to reduce its complexity and cost, Fabry-Perot Bragg Grating (FPBG) based devices are strong candidates to be used in these networks. In the presented work, the same device is able to provide functionalities like optical carrier recovery in a wavelength division...
We report on the recent progresses in the wavelength-division-multiplexed passive optical network (WDM PON) based on the reflective semiconductor amplifiers (RSOAs), including the enhanced operable temperature range, effects of reflection and its mitigation methods, 10 Gb/s operation by using electronic equalizers and forward error-correction (FEC) codes, and increased maximum reach to >100 km...
Optical and wireless integration in the same platform is an essential requirement for future access networks in order to achieve an economically feasible business model, especially for the deployment of Next Generation Networks. The combination of both technologies offers high bandwidth together with mobility, thus making a strong contribution to future high capacity applications. PON (passive optical...
