波分复用器及其优缺点.ppt,波分复用器概述 WDM技术是指将两种或多种不同波长的光载波信号在发送端经过复用器(或称合波器,Multiplexer)汇合在一起,并耦合到光线路中的同一根光纤中进行传输的技术:在接收端,混合信号再经过解复用器(或称分波器,Demultiplexer)将各种波长
(1)数据选择器(Multiplexer)数据选择器根据地址选择码从多路输入数据中选择一路到数据输出端输出,常用的数据选择器有二选一(74LS157、74LS257)、四选一(74LS153、74LS253)、八选一(74LS151、74LS251)和十六选一(74LS150等)。(2)数据分配器(Demultiplexer)数据分配器是将一路输入数据根据地址选择码分配给...
Demultiplexer: 分用器,multiplexer: 复用器 FDM can be used with analog signals. TDM can be used with digital signals or analog signals. Two types of TDM: synchronous TDM statistical TDM: provides more efficient service This chapter concentrates on three types of multiplexing techniques. The first,...

Bits and Bytes Computers work with on’s and off’s – Binary digital values 0 and 1. Binary digits (bits) are usually organised into groups of 8 – a byte. We can use a byte to represent a whole number (integer), a fraction (real) and a character. We can also represent negative...
