光通信用光接收机技术及其进展

Technique and development of optical receiver

光接收机是光纤通信系统的重要组成部分,它的作用是将由光纤传来的微弱光信号转换为电信号,经放大、处理后恢复原信号。光接收机的性能对整个系统的通信质量有很大的影响。从不同的角度对光接收机进行了分类,进而分析了光接收机技术的最新进展,最后对光接收机技术的发展进行了展望。

Optical receiver is a most important part in optical fiber communication system. The main effect of it is to transform the weak light signal passed from optical fiber into electrical signal. After enlargement it can return to original signal. The capability of the optical receiver have a great impact on the communication quality in the whole system. From the different perspectives the optical receiver has been classified. then analyses the latest progress of it. Finally, the future development is proposed appropriately.
