Conclusion

Although the current 5G is still in the standard stage, major equipment manufacturers have actively carried out joint trials with operators to strive to achieve 5G commercial use by 2020. Recently, the ministry of industry and information technology issued 5G licenses to four enterprises. It means that 5G has started in China.
Compared with 4G technology, the 5G data transmission rate is 10 to 100 times that of 4G, which means that the number of optical transceivers used by a single base station will increase substantially when the optical transceiver rate remains unchanged.
>Under the 5G era, the optical transceiver will become one of the most flexible segments in the 5G industry chain. In addition, the demand for optical transceivers for the construction of large-scale data centers will also increase with the outbreak of 5G traffic.
