400 Gbit/s FR4光收发模块的研究

Research on 400 Gbit/s FR4 Optical Transceiver Module

如今数据中心的业务流量需求急剧上升,很多服务商早已开始着手400 Gbit/s以太网通信系统的建设。相比于100 Gbit/s光模块,400 Gbit/s光模块可提供更高的传输带宽以及更低的功耗和成本。针对上述需求,文章提出了一种应用于数据中心光通信网络系统的400 Gbit/s光收发模块设计方案。首先介绍了400 Gbit/s光模块的相关协议及标准,然后给出了模块的总体设计框架,主要从速率转换、发射、接收和监控4部分进行了阐述,最后对该模块进行了测试。测试结果表明,该模块符合各项协议与标准的规定,是一种能实现数据中心400 Gbit/s以太网传输的良好解决方案。

With the demand of data center traffic soaring, many service providers are already working on 400 Gbit/s Ethernet communication systems. Compared with the 100 Gbit/s optical module, the 400 Gbit/s optical module can provide higher transmission bandwidth with lower power consumption and cost. Aiming at the above requirements, this paper proposes a design scheme of 400 Gbit/s optical transceiver module for data center optical communication network system. We first introduce the 400 Gbit/s optical module related protocols and standards. Then we present the general design of the module framework, mainly from the rate of conversion, launch, receive and monitoring 4 parts. Finally, we conduct a performance test and the test results show that the module in accordance with the agreement and the provisions of the standard, which is a good solution to realize data center 400 Gbit/s Ethernet transmission.
