Abstract

The structural design and the measured characteristics of optical signal amplification unit for 640 Gbps (10 Gbps$\times$64 ch.) WDM transmission systems are reported. The unit is composed of two sub gain block units for the amplification of C-band (1530-1560 nm) and L-band (1570-1600 nm), respectively. Programmable microprocessors monitor the states of operation and optimize the optical output conditions. Each sub gain block unit can maintain total optical output power of +21 dBm with gain flatness of < 1 dB and noise figure of <7.2 dB for the input power in the dynamic range from-5 to +1 dBm.+1 dBm.

1530-1560nm와 1 570-1600nm 대역에서 이득을 갖는 640Gbps(10 Gbps$\times$64채널) 파장 다중화된 광신호 증폭용 유니트를 설계, 제작하고 특성을 측정하였다. 640Gbps 광신호 즈옥 유니트의 이득 블록은 최적 광출력 특성을 유지하고 이득 불록의 동작 상태를 감시할 수 있도록 마이크로 프로세서에 의해서 제어된다. 640 Gbps 광신호 증폭 유니트의 각 대역별 광증폭 유니트는 총 입력 광 세기 범위 -5~+1 dBm에서 이득 평탄도 1dB이내 잡음 지수 7.2dB 이내 +21dBm 이상의 고출력 특성을 갖는다.
