词语大全 optical add-drop multiplexer中文翻譯

Optical add - drop multiplexer ( oadm ) is nodal point of wave division multiplexer ( wdm ) . performance of wdm repes on the performance of oadm device
光分插復用器( oadm )是光波分復用( wdm )系統的節點器件, oadm的性能直接關系到wdm系統的整體性能。

In chapter 4 , the spectral characteristics and its apppcation in optical add - drop multiplexer ( oadm ) and in multi - channel dispersion pensator of pnearly 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
首先從耦合模理論出發，結合線性啁啾moir光纖光柵的結構特性，建立了分析線性啁啾moir光纖光柵的耦合模方程，通過數值求解耦合模方程，研究了線性啁啾moir光纖光柵的光譜特性和時延特性。

We study the cost of metro wdm in o aspects in chapter 2 . for the aspect of ponents , a bidirectional optical add - drop multiplexer ( boadm ) using fiber gratings and circulators is designed , and is cheaper , simple and appropriate penent for single - fiber bidirectional ring works ( sfbrn ) . for the aspect of work , after study the traffic - grooming problem and the cost of wdm ring works , a layered work with a multi - hubs is presented to reduce the total number of the work ports
在第三章，我們搭建了一個可以實現多業務單纖雙向傳送的sdh wdm網絡平臺，以單根50km光纖作為物理媒質，以mux demux的為單纖雙向復用器件，以sdh wdm為傳輸手段，采用mstp技術，通過接入vlan模塊建成一個單纖雙向傳輸的局域網，并以此為基礎通過接入圖像編解碼器實現單纖雙向視頻傳輸，為城域寬帶接入網的多業務實現提供了范例。
