2020 is a recognized year for 5G construction in the industry. With the continuous increase of new infrastructure and policies, 5G is poised. As we all know, the 5G frequency band is mainly divided into two categories which are Sub-6GHz and millimeter wave (24GHz-86GHz).

About optical to electrical interface of the active optical cable, it can be realized by two technologies. Detail description about the two technologies as below.

Data center 100G has already begun to be used on a large scale, and the next generation of 400G is expected to begin commercial use gradually in 2020. For 400G applications, the biggest difference is the introduction of a new modulation format PAM-4, which has achieved the effect of doubling the transmission rate at the same baud rate (device bandwidth), such as DR4 for transmission below 500 meters, single-wave rate Need to reach 100Gbps.
