Findings on Optical Research from P.K. Chowdhury and Colleagues Provide New Insights

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Optical Research. According to news reporting originating in Khulna, Bangladesh, by VerticalNews editors, the research stated, "An extended reach 10 Gb/s wavelength division multiplexing passive optical networks (WDM-PONs) system based on reflective semiconductor optical amplifier (RSOA) is proposed by using power pre-emphasized orthogonal frequency division multiplexing (OFDM) signal."

The news reporters obtained a quote from the research, "Experimental results show that the proposed technique can effectively enhance the system performance against the limited bandwidth and chirp induced fading effect from direct modulation of RSOA."

According to the news reporters, the research concluded: "The receiver sensitivity is improved by 5 dB at the limit of BER for forward error correction (FEC) code over the 60 km and 85 km fiber transmission without any dispersion compensation module."
