Abstract

In this paper, the bandwidth of the filters used in optical communication systems and systems for the correlation between the error probability has been studied. Preamplifier that occurs in the system error probability as a function of the sensitivity of the receiver on the receiver sensitivity was shown for the various error probability calculation is performed. In addition, the channel data rate on the probability of various errors, changes in the function of the optimal bandwidth for the receiver filter was calculated, as required to operate at optimal range of the filter bandwidth, data rate per channel in a 10Gb/s the range of when is between 0.2 and 3.5nm.

본 논문에서는 광통신시스템에서 사용되는 필터의 대역폭과 시스템의 에러 확률과의 상관관계에 대해 연구를 수행하였다. 이를 위하여 전치증폭시스템에서 발생하는 에러확률을 수신기의 감도에 관한 함수로 나타내었으며 수신기 감도를 다양한 에러 확률에 대해 계산을 수행하였다. 또한 다양한 에러확률에 대한 채널당 데이터 전송률의 함수의 변화에 대한 수신기 필터의 최적의 대역폭을 계산하였는데, 같이 최적 상태에서 동작하기 위해 필요한 필터의 대역폭 범위는 채널당 데이터 전송율이 1에서 10Gb/s의 범위일 때, 0.2에서 3.5nm 사이이다.
