“…RSOA의 구 동 전류 (driving amplitude) 와 바이어스 전류 (bias current) 를 함께 조정해서 5 dBm의 출력 세기가 되도록 조정했는데 이 조정 값의 크기는 하드웨어 실험을 통해 결정하였다. [12,14] . 구동 전류는 1.25 Gbit/s 전송 속도의 NRZ (non-returnto-zero) 신호 포맷으로 변조되었다.…”

The AWG-filtering effect was investigated on a bidirectional 100-GHz-channel-spacing WDM-PON link using spectrum-sliced and RSOA-amplified light sources for downstream signals and a wavelength reuse technique for upstream signals. Signal performances of three different filtering AWGs, including Gaussian, trapezoidal, and rectangular types, were compared on link transmission with fiber nonlinear effects. As an extinction ratio of a downstream signal varied, the effect for both directional signals was analyzed and optimized. It was found that there was an optimal pass bandwidth of an AWG for the balance between relative intensity noise decrement and cross phase modulation noise increment as the bandwidth got wider.

“…At this injection power, the PDG was about 0.6 dB. Thus, we can consider the PI F-P LD as an RSOA with the PDG of 0.6 dB and spectral ripple of 2 dB [13]. To check the spectral characteristics of the F-P LD/RSOA, we measured the spectra according to the bias current and the temperature without the ASE injection as shown in Fig.…”

We investigate a high capacity WDM-PON based on wavelength-locked Fabry-Perot laser diodes. A color-free transmission of 2.5 Gb/s per channel is achieved with a polarization independent F-P LD and a decision threshold control circuit at the receiver. Then, we demonstrate an 80 Gb/s capacity (2.5 Gb/s x 32 channels) WDM-PON with transmission length of 20 km. We also investigate impairments in transmission.
