摘要
在实际应用中为满足对多业务大气传输光通信的要求,研究并实现了通信速率达42.24 Mbits/s的大气传输光通信系统,该系统能够实现V.35、E1、RS-232/485、以太网以及电话语音数据通信等.从光学收发天线、半导体激光器调制驱动电路、光电二极管(PIN)直接检测电路、通信端机等方面阐述了该系统的基本原理、组成结构以及设计思路等.大气传输通信实验表明,传输距离为500 m时,在晴朗的天气条件下该系统能实现宽带、高速、低误码率的信息传输.
Abstract
A 42.24 Mbits/s atmospheric laser communication system was developed based on the demand for the multi-service atmospheric laser communication in practice. It could achieve the communications of the V.35, E1, RS-232/485, Ethernet, and phone. Design consideration, basic principle and system architecture of the multi-service atmospheric laser communication system were demonstrated. The atmospheric laser communication experiment shows that the system can implement the communication with broadband, high speed and low bit-error in the cloudless condition, and availabe distance is 500 m.
