Demonstration of a Bidirectional WDM-PON with 10 Gb/s Downstream DQPSK and 5 Gb/s Upstream Re-modulated OOK Data Based on Reflective Semiconductor Optical Amplifier
نویسنده
چکیده
We propose a bidirectional wavelength division multiplexing passive optical network (WDM-PON) based on a reflective semiconductor optical amplifier (RSOA) by employing a differential quadrature phase shift keying (DQPSK) signal for down-link and an on-off keying (OOK) re-modulated signal for up-link over 45km SMF colorless WDM-PON without dispersion compensation was demonstrated for both 10 Gbit/s DQPSK downstream signal and 5 Gbit/s OOK upstream signals. We investigate the impact of injection power to the RSOA on upstream data including BER performance for both downlink and uplink with the variation of transmission distance. It is observed that the proposed scheme is as good as those in case of continuous wave light injected RSOA. So, the simulation result is to meet the data rate and cost-efficient of the optical links simultaneously in tomorrow’s WDM-PON access networks. Keyword: WDM-PON, RSOA, DQPSK, OOK.

In this paper it is proposed and investigate a Wavelength Division Multiplexing Passive Optical Network (WDM-PON) ring providing Rayleigh backscattering (RB) noise reduction. Besides, the ring-based architecture also could reduce the RB beat noise .This is possible because RB and upstream signal are moving in opposite direction. In the proposed PON system, we have discussed and did analysis cha...

We demonstrate the 40-Gb/s upstream transmission in the 60-km reach wavelength-division-multiplexed passive optical network (WDM PON) implemented by using directly modulated reflective semiconductor optical amplifiers (RSOAs) and self-homodyne receivers. It is difficult to operate the RSOA at 40 Gb/s due to its limited modulation bandwidth. To overcome this problem and generate 40-Gb/s upstream...
