According to the latest report, although the deployment of FTTH and 4G LTE infrastructure in China has reached the peak, FTTx support and FTTH mobile access network are rapidly built. Meanwhile, with the accelerated development of 4K video and 5G technology, PON technology supporting 25G/100G higher rate is gradually becoming the research hotspot in the industry.The overall market demand for optical communication equipment and instruments will continue to grow in the next five years.

In 2016, the global sales volume of optical devices exceeded 115 million units, creating a revenue of about 1.7 billion us dollars.Nearly 70 percent of these optical devices will be deployed in China.

China's demand for similar optical devices and equipment will flatten between 2017 and 2021.

However, during the forecast period, the deployment of access infrastructure in developing countries and the sale of next-generation optical fiber in developed countries will pick up, thus maintaining the continuous growth of the market.

Global mobile infrastructure and FTTx device sales will exceed $2 billion in 2021.

Although China's market share will slip to 50%;Despite setbacks in the domestic market, Chinese equipment manufacturers will also benefit from the rest countries of the world, including developing markets, through product upgrades and exports of expertise.

Meanwhile, since the deployment of 5G mobile infrastructure will start from 2020, it will drive the development of the entire wireless and optical communication market.

However, the Retimed Ethernet could well replace CPRI connections.This is because retiming Ethernet requires less bandwidth than CPRI, and using CPRI would limit the application's high-speed optical device sales growth.
