Abstract

The effect of alternate polarization (alP) has been investigated for 400 × 200 Gbps super dense wavelength division multiplexing (SD-WDM) system using RAMAN-EDFA-RAMAN hybrid optical amplifier (HOA). Further evaluation has carried out for the characteristics of bit error rate (BER) and quality factor (Q-factor) for enhance long haul optical communication. Remarkable performances have recorded by al-PNRZ modulation technique with acceptable outcome in terms of quality factor (Q-factor) 20.5 dB and bit error rate (BER) of 10^–40 with 100 GHz channel spacing.

使用混合光放大器的交替偏振对SD-WDM系统的影响

摘要

对于使用RAMAN-EDFA-RAMAN混合光放大器（HOA）的400×200 Gbps超密集波分复用（SD-WDM）系统，已经研究了交替偏振（alP）的影响。对于误码率（BER）和质量因数（Q-factor）的特性已经进行了进一步评估，以增强长距离光通信。通过al-PNRZ调制技术，在100 GHz信道间隔的20.5 dB的质量因数（Q-factor）和10 ^–40的误码率（BER）方面，已取得了可观的结果。
