In order to solve the problem of electronic bottleneck, photonics technology is adopted by using OADM and OXC in nodes.
Design and Implement of Modular OADM in WDM Optical Network;
爲了解決交換中日益嚴重的電子瓶頸問題，在節點處引入光子技術，使用了OADM和OXC。
爲此，文章對OXC/OADM的關鍵技和解決方案進行了介紹，並對OXC/OADM的發展進行了展望。
SHAONET是國內自主開發的第一個WDM全光試驗網平臺，它採用了一種新型保護結構的OADM，具有很強的自愈功能。
Research of the Optical ADD and DROP Multiplexer (OADM) Based on the Acousto-Optic Tunable Filter (AOTF);
The isolation of add/ drop ports and the channel insertion loss of OADM are measured.
