ＳＤＨ 微波通信是新一代的数字微波传输体制。数字微波通信是用微波作为载体传送数字信息的一种通信手段。它兼有ＳＤＨ 数字通信和微波通信两者的优点，由于微波在空间直线传输的特点，故这种通信方式又称为视距数字微波中继通信。 一、SDH微波通信系统的组成 数字微波传输线
SDH microwave communication is a new generation of digital microwave transmission system. Digital microwave communication is a means of communication that uses microwaves as a carrier for transmitting digital information. It combines the advantages of both SDH digital communications and microwave communications, because of the characteristics of linear microwave transmission in space, so this communication is also known as line of sight digital microwave relay communications. A, SDH microwave communication system composed of digital microwave transmission line
