现有铁路通信传输容量越来越满足不了通信发展的需求,WDM技术是解决问题的惟一现实的手段,本文简要介绍了WDM技术,着重研究了如何将WDM技术具体应用到既有铁路通信系统中去,以适应铁路通信的发展。
The existing railway communication transmission capacity can not meet the demand of communication development more and more. WDM technology is the only realistic means to solve the problem. This article briefly introduces the WDM technology and focuses on how WDM technology can be applied to the existing railway communication system Go, to adapt to the development of railway communications.
