设计并研制出了一种可灵活重构的多波长OADM ,建立了OADM级联光信噪比的理论计算模型并进行了分析计算 ,给出了OADM的内部功率预算 最后对OADM设备进行了测试 ,所有性能指标都达到设计要求 ,目前已经通过工程验收 ,并正式在“中国高速信息示范网 (CAINOnet)”中运行 A flexible reconfigurable multi-wavelength OADM was designed and developed. The theoretical calculation model of OADM cascaded optical signal-to-noise ratio was established and analyzed. The internal power budget of OADM was given. Finally, OADM equipment was tested , All the performance indicators have reached the design requirements, has now passed the project acceptance, and officially run in the “China High-speed Information Network (CAINOnet)”
