Fiber-optic communication breakthroughs are presented every year at the Optical Communication Conference, OFC. This paper reviews some of the key papers presented at the OFC 2019, held March 3 through 7 in San Diego, CA. Some of the conference themes were: Data Center Connectivity, 5G Networks, and major advances in components and in communication systems. The Conference stressed the work carried out by the Optical Internetworking Forum, OFI, which developed the 400 ZR standard for 400 Gigabit fiber modules. This standard enables interoperability between transceiver manufacturers. (See link: https://www.oiforum.com/technical-work/hot-topics/400zr-2/)

每年在OFC的光通信大会上都会介绍光纤通信的突破。本文回顾了3月3日至7日在加利福尼亚州圣地亚哥举行的OFC 2019上提出的一些关键论文。会议主题包括：数据中心连接性，5G网络以及组件和通信系统的重大进步。会议强调了光纤互联网络论坛OFI所做的工作，该论坛为400个千兆光纤模块制定了400 ZR标准。该标准实现了收发器制造商之间的互操作性。（请参阅链接：https://www.oiforum.com/technical-work/hot-topics/400zr-2/）
