The amount of information required in the ICT market is increasing at a faster rate than expected, and the practical application of ultrahigh-speed optical transceivers and optical components with transmission speeds up to 400 Gb/s or higher is rapidly progressing. These optical transceivers and optical components need to be developed with higher transmission speed, smaller size and lower power consumption, necessitating the adoption of optical integrated technologies and fine CMOS processes. Under these circumstances, international standardization bodies such as IEEE 802.3/OIF/IEC and other MSA groups are actively creating standards, and this paper reports mainly on these latest topics.
