【摘要】 100G以太网技术中接口和传输是两项关键技术,与现有10G以太网技术相比,100G以太网可提供统一的接口标准和更高的带宽。100G以太网传输中存在较强的衰减和色散,PM-QPSK编码采用相干检测和偏振复用技术较适合高速以太网传输。通过对100G核心路由产品和高速以太网应用需求的分析,100G以太网在城域网和企业级数据中心的实际应用中还应该在接口标准和兼容性方面加以研究和改进。更多还原

【Abstract】 The interface and transmission are two key technologies in the 100G Ethernet.Compared with the existing 10G Ethernet technology,100G Ethernet can provide a unified interface standards and higher bandwidth.In the 100G Ethernet transmission there is a strong attenuation and dispersion.PM-QPSK encoding which includes polarization multiplexing and coherent detection technologies is more suitable for high-speed Ethernet.更多还原
