Today's New Generation Optical Transport Network


Although China's share of the global PON market dropped from 80% in 2017 to 74% in 2018, it is still the most important PON market in the world, Dai said. The market share of Asia-Pacific (except China) has increased from 6% in 2017 to 11% in 2018. The performance is good. The Asia-Pacific market is likely to become an important growth pole of the global PON market in the next few years.


According to the trend of global PON product investment, 2.5GPON OLT/ONU will remain the most important product in the global PON market in the next three years, but it will begin to weaken year by year. 10GPON OLT/ONU will begin to usher in the time window of rapid outbreak, and the annual compound growth rate is expected to reach more than 50%. This will also lead to increasingly fierce market competition, PON optical module product prices will also show an avalanche decline.


According to Dai Qiwei, power budget is one of the main problems facing optical modules at present. Although SOA can be used to amplify power, Burst mode EDFA can be used to amplify power, and FEC or built-in DSP can be strengthened to improve power budget, it also brings many problems such as complex process, calculation, additional equipment, power consumption, and high price. This also means that the next generation of PON products have higher and more requirements for optical devices.


​Dai Qiwei holds high expectations for the future of the optical device industry, and hopes to solve the problems of mass delivery and cost reduction, performance and cost balance in the optical device industry as soon as possible in the future.
