Abstract

We report 1.6 Tb/s (160${\times}$10 Gb/s) WDM transmission over 2,000 km of single mode fiber using distributed hybrid(distributed Raman amplifier＋Erbium-doped fiber amplifier) optical amplifiers. After transmission over 2,000 km of single mode fiber, average optical signal to noise ratios of C/L-band were 20.5 dB, 21.9 dB, respectively. The minimum Q-factors of each band were 14.65 dB (BER=5.8e-8) in C-band, 13.75 dB (BER=5.0e-7) in L-band without forward error correction. We performed 1.6 Tb/s error-free transmission over 2,000 km of single mode fiber using Reed-Solomon (255, 239) forward error correction code.

분산형 라만 광증폭기와 어븀 첨가 광섬유 증폭기로 구성된 복합형 광증폭기를 사용하여 1.6 Tb/s (160${\times}$10 Gb/s) 전송 용량의 WDM 광신호를 단일 모드 광섬유 2,000 km에 전송한 결과에 대하여 기술한다. 복합형 광 증폭기를 사용하여 단일 모드 광섬유 2,000 km에 전송한 뒤의 평균 광 신호대 잡음비는 C/L-band에서 각각 20.5 dB, 21.9 dB 였고, 최저 Q-factor는 C/L-band에서 각각 14.65 dB(BER=5.8E-8), 13.75 dB(BER= 5.0E-7)였다. 이 결과에 Reed-Solomon (255, 239) Forward Error Correction(FEC) 코드 기능을 사용하여 무오류 전송 결과를 얻었다.
