Abstract
버스트모드 광송신기가 개시된다. 버스트모드 광송신기는 버스트모드 제어 신호에 따라 ONU의 매체 접근 제어(Media Access Control, 이하 MAC)로부터 유효데이터 신호와 아이들(Idle) 신호로 구성된 MAC 전기신호를 수신하는 클럭 및 데이터 복원 회로; 상기 클럭 및 데이터 복원 회로를 통해 클럭 및 데이터가 복원된 MAC 전기신호와 상기 버스트모드 제어 신호를 이용하여 상기 MAC 전기신호에 포함된 아이들 신호를 제거하는 연산 회로; 상기 아이들 신호가 제거된 MAC 전기신호를 이용하여 광원의 변조에 필요한 전기 신호를 출력하는 변조전압 출력 회로; 및 상기 변조전압 출력 회로를 통해 출력된 전기 신호에 기초하여 상기 광원이 광신호를 출력하기 위한 동작 전원을 제공하는 바이어스 전압 공급 회로를 포함할 수 있다.
