본 논문에서는 광파 통신 링크를 설계하는 방법을 분석하기위한 새로운 기술을 제시하고, 특히, p-i-n다이오드 또는 애벌런치 포토다이오드와 같은 광투사 다이오드를 이용한 직접 검파, 단일 모드 광섬유 링크 소개하고, 성능 및 비트오율을 파라미터에 따라 분석한다. 대부분의 통신망에서 광섬유 통신링크가 사용되고 있고, 광섬유링크는 넓은 대역폭을 갖고 있다. 이러한 대역폭을 이용하기 위한 파장분할 다중화에 대하여 분석하고, 여러 파라미터 집합으로 다양한 서브시스템의 적절한 값들을 찾아내어 목표한 성능을 만족시키도록 한다. 유효값의 범위에 따라 많은 파라미터값을 갖지만, 컴퓨터의 처리 능력이 급속하게 증가하고 있으며, 증가 된 능력을 사용하는 한 가지 방법은 컴퓨터가 매개 변수들의 최적의 조합을 검색하여 세부 사항을 처리하는 것인데, 애벌런치 포토 다이오드의 파라미터들 즉 평균이득, 이온화율, 암전류 값에 따른 비트오율과 p-i-n 다이오드에서 샘플링주기에 따는 비트오율분석을 통하여 광파통신링크의 성능을 분석한다.
Abstract
In this paper, we present the new techniques to analyze how to design a lightwave communications link. Specially, we introduce a direct detection, single mode fiber link utilizing a light emitting diode source, and either a pin photodiode or avalanche photodiode receiver, We discuss about a point to point link, even though an optical fiber communications link is usually part of a larger communications network. The optical fiber link has enormous bandwidth. Wavelength division multiplexing is one way of utilizing this bandwidth. Ideally, the purpose is to find a set of parameter values for the various subsystems in the link that will satisfy certain performance objectives. There can be a large number of parameters, each having a range of valid values. Processing power of computers is increasing at a rapid rate, and one way to take advantage of this increased power is to let the computer handle the details of searching for the optimal set of parameter values. The research for an acceptable design is based on multiple simulations, and is a trial and error search if done manually. we give a general method of the modeling approach, the key blocks and parameters of a lightwave communications link.
