Abstract

We have developed an optical video transmission device for HD-SDI signal transmission. The optical transmitter/receiver unit operates at DC 5 volt and small enough to be attaced near surveillance camera. They have internal voltage regulating circuits to supply 3.3V to other circuits inside the unit. The optical transmitter is composed of cable driver, laser diode driver, and laser diode. The optical receiver is composed of photodiode, limiting amp, and cable equalizer. The wavelength of the trasmitter was 1.3 um, and optical power was -5dBm, and the speed was 1.485Gbps. The receiver sensitivity was -23 dBm. We confirmed that the optical device can transmit HD-SDI video through 30 km optical fiber without any interruption.

HD-SDI 비디오 신호 전송을 위한 광 비디오 전송 장치를 개발하였다. 광 송수신기는 입력전원 DC 5V로 동작하며, 감시 카메라 주위에 부착 가능하도록 작은 크기로 개발하였다. 광 송수신기는 내부에 별도의 전원 안정화 회로를 내장하여, 출력이 안정된 3.3V 전압을 내부의 다른 전자회로에 공급하도록 하였다. 광 송신기는 케이블드라이버, 레이저 다이오드 드라이버, 레이저 다이어드로 구성되며, 광수신기는 포토다이오드, 리미팅 앰프, 케이블 이퀄라이저로 구성하였다. 광 송신기는 파장 1.3.um, 광출력 -5 dBm, 송신속도 1.485Gbps였고, 광 수신기는 수신감도 -23dBm이었다. 이 장치로 HD-SDI 비디오 신호가 광섬유 30km 광섬유 전송 후에도 끊김 없이 전송됨을 확인하였다.
