The most commonly used optical transmitters are semiconductor devices such as light-emitting diodes (LEDs) and laser diodes. The difference between LEDs and laser diodes is that LEDs produce incoherent light, while laser diodes produce coherent light. For use in optical communications, semiconductor optical transmitters must be designed to be compact, efficient, and reliable, while operating in an optimal wavelength range, and directly modulated at high frequencies.

레이저 다이오드는 종종 직접 변조되어, 그 광 출력이 디바이스에 직접인가 전류에 의해 제어되고있다.

수신기

광 수신기의 주성분은 광전 효과를 이용하여 빛을 전기로 변환하는 광 검출기이다.

Optical-electrical converters are typically coupled with a transimpedance amplifier and a limiting amplifier to produce a digital signal in the electrical domain from the incoming optical signal, which may be attenuated and distorted while passing through the channel. Further signal processing such as clock recovery from data (CDR) performed by a phase-locked loop may also be applied before the data is passed on.

An optical fiber consists of a core, cladding, and a buffer (a protective outer coating), in which the cladding guides the light along the core by using the method of total internal reflection. The core and the cladding (which has a lower-refractive-index) are usually made of high-quality silica glass, although they can both be made of plastic as well.

광섬유 통신에 사용되는 광섬유의 두 가지 주요 유형은 다중 모드 광섬유와 단일 모드 광섬유 (가) 있습니다.

앰프

광섬유 통신 시스템의 전송 거리 전통적 섬유 감쇠에 의해 섬유 및 왜곡에 의해 제한되었다.

다른 방법은 전기 도메인으로 신호를 변환하지 않고 직접 광 신호를 증폭하는 광 증폭기를 사용하는 것이다.
