| Abstract: | The important function of the multiplex communication system in a Reconfigurable multichannel Optical Add and Drop Multiplexer(ROADM) node is analyzed,as if a bridge between the network management and all the entity functions,which can provide the channels for information changed and accomplish the commands from the network management.The multiplex communication system is based on ATmega128 single chip and programmed with C/C~( ) language,and it realizes the correspondence of the back board through SPI interface and RS 485 communication bus.Specially,the architecture of the control software is presented,as well as the implementation scheme. |
