The required information volume in the ICT market is increasing faster than expected, and ultra-high-speed optical transceivers/optical components with transmission speeds of 400G or higher are rapidly being put into practical use. Along with higher speeds, these optical transceivers/components are required to be smaller and have lower power consumption, requiring the application of optical integration technology and fine CMOS processes. Under these circumstances, international forum standardization organizations such as IEEE802.3/OIF have started standardization of ultra-high-speed optical transceivers beyond 800G by 2021. In this report, we will focus on the latest topics of the standardization organizations and address the issues toward practical application of 800G/1.6T.
