   自2018年腾讯公司提出开始关注400G的下一代数据中心网络升级以来,罗森伯格与腾讯公司在400G的应用技术方面持续保持着密切地交流与配合。4月10日,由腾讯联合罗森伯格、思科、Ixia以及众多光模块厂家共同组织的“400G互联互通组网性能测试”在腾讯 北京公司举行,腾讯公司本次测试是国内最早、最先进、最全面的400G测试。本次400G的测试,将为整个数据中心行业进入400G的商用又向前迈进了一步,具有里程碑的意义。

  Since Tencent began to pay attention to the next generation data center network of 400G in 2018, Rosenberger and Tencent have maintained close communication and cooperation in the application technology of 400G. On April 10th, the "400G Interconnection Networking Performance test" organized by Tencent, Rosenberger, Cisco, Ixia and many optical transceiver manufacturers was held in Tencent Beijing. Tencent's test is the earliest, most advanced and most comprehensive 400G test in the industry. This 400G test will be a milestone for the entire data center industry to enter 400G business application.

  根据IEEE与MSA所提出的400G应用模型的种类超过10种以上,不同光模块厂家产品差别极大。400GBASE-SR8、400GBASE-SR4.2、400GBASE-DR4、400GBASE-FR8等等各种传输模型均有厂家推出。就算选择其中的一种传输方案也有各种不同接口的选择,例如400GBASE-SR8,端口就有16芯、24芯之分,还有APC和UPC的端面类型区分,如下图所示。

  According to more than 10 kinds of 400G application models proposed by IEEE and MSA, the products of different optical module manufacturers are very different. Various transmission applications, such as 400GBASE-SR8, 400GBASE-SR4.2, 400GBASE-DR4, 400GBASE-FR8, have been introduced by manufacturers. Even if one of the transmission schemes is chosen, there are various interface choices, such as 400GBASE-SR8. Ports can be divided into 16 cores and 24 cores, and APC and UPC types can be distinguished, as shown in the following figure.

  为了此次测试,罗森伯格提供了全套的400G数据中心布线方案,包括各种端口类型的传输跳线,采用单模、多模OM3、OM4以及最先进的OM5光纤,全面支持了业界各种400G传输模型。基于罗森伯格提供的400G模型,整体物理通道全部采用业界最高精度的超低损耗连接器,保证了物理通道性能的稳定性与可靠性。

  For this test, Rosenberger provides a full set of 400G data center cabling solutions, including various types of port transmission jumpers, using single-mode, multi-mode OM3, OM4 and the most advanced OM5 optical fibers, which fully supports the industry's various 400G transmission models. Based on Rosenberger's 400G solutions, all physical channels adopt ultra-low loss connectors with the highest accuracy in the industry, which ensures the stability and reliability of physical channel performance.

  通过实际组网测试发现,市面上各种品牌的400G光模块性能参差不齐,端口类型也是千差万别。不同厂家光模块组网互测兼容性状况当前来看总体还不太乐观,甚至同一厂家的不同批次,传输性能也有一定的差异。当然也有部分品牌的产品已经达到了较为理想的性能。

  Through the actual networking test, it is found that the performance of 400G optical transceivers of various brands on the market is different, and the port types are also very different. At present, the compatibility of optical transceiver networking among different manufacturers is not very optimistic. Even in different batches of the same manufacturer, the transmission performance is also different. Of course, some brands of products have achieved better performance.

  罗森伯格本次独家提供了整套400G数据中心布线系统涵盖了全部种类的400G接口。例如MTP跳线就有16芯UPC、16芯APC、24芯UPC、24芯APC等多种类型。罗森伯格公司能够为应对所有的当前标准化的400G应用提供完善的解决方案,如果未来光模块接口类型能够更加统一,这对于整个行业的长足发展更有利。

  Rosenberger exclusively provided a complete set of 400G data center cabling system covering all kinds of 400G interfaces. For example, MTP jumper has 16 core UPC, 16 core APC, 24 core UPC, 24 core APC and other types. Rosenberger can provide perfect solutions for all current standardized 400G applications. If the interface types of optical modules can be more uniform in the future, it will be more beneficial to the development of the whole industry.
