摘要:
利用光纤通信系统原理综合实验箱, 可有效实现一个基本的数字电话基带直传, 描述了该实验的工作原理及具体实现.在短距离传输的基带直传方式中, 要增加单模光纤的带宽, 应采用1B2B 的CMI码,这样信道编码的误码增值几乎为零,大大提高信噪比,改善传输质量.并在此基础上讨论及分析了一般光纤通信系统的运作原理及其技术特点 .
Abstract:
Using the synthetical experimental box of the optical fiber communication system principle , it is possible to carry out a baseband transmission of digital telephone effectively . We have described the principle and the operation process of the system in detail. By the way of baseband transmission in short distance communication , we can widen the bandwidth of single mode fiber with 1B2B code and CMI code techniques in communication . As a result the increment of error code approaches to zero , but the increment of signal to noise ratio is remarkable, so we can improve the communication quality . In the end , we have analyzed the normal optical fiber communication principle and the technical points .
