optical add-drop multiplexer meaning in English
光塞取多工机
Examples
- Optical add - drop multiplexer ( oadm ) is nodal point of wave division multiplexer ( wdm ) . performance of wdm relies on the performance of oadm device
光分插复用器( oadm )是光波分复用( wdm )系统的节点器件, oadm的性能直接关系到wdm系统的整体性能。 - In chapter 4 , the spectral characteristics and its application in optical add - drop multiplexer ( oadm ) and in multi - channel dispersion compensator of linearly chirped moir fiber grating are studied . according to the coupled - mode theory and considering the construction features , we derive the couple - mode equations that describe the mode interaction in this kind of grating
首先从耦合模理论出发，结合线性啁啾moir光纤光栅的结构特性，建立了分析线性啁啾moir光纤光栅的耦合模方程，通过数值求解耦合模方程，研究了线性啁啾moir光纤光栅的光谱特性和时延特性。 - We study the cost of metro wdm in two aspects in chapter 2 . for the aspect of components , a bidirectional optical add - drop multiplexer ( boadm ) using fiber gratings and circulators is designed , and is cheaper , simple and appropriate compenent for single - fiber bidirectional ring networks ( sfbrn ) . for the aspect of network , after study the traffic - grooming problem and the cost of wdm ring networks , a layered network with a multi - hubs is presented to reduce the total number of the network ports
在第三章，我们搭建了一个可以实现多业务单纤双向传送的sdh wdm网络平台，以单根50km光纤作为物理媒质，以mux demux的为单纤双向复用器件，以sdh wdm为传输手段，采用mstp技术，通过接入vlan模块建成一个单纤双向传输的局域网，并以此为基础通过接入图像编解码器实现单纤双向视频传输，为城域宽带接入网的多业务实现提供了范例。
