Global PON (Passive Optical Network) ONU (Optical Network Unit) equipment shipments have benefited from tens of millions of new subscribers every year in Chinese market since 2016. The output of ONU terminals exceeded 100 million units in both 2016 and 2017 with value of nearly USD 4.4 billion and USD 3.9 billion, respectively. The fierce competition not only has benefited the FTTH (Fiber To The Home) supply chains that cover upstream components and downstream OEM/ODM assembly services but also has lured more Chinese players to join the bandwagon. It is estimated PON ONU equipment shipment volume will top 90 million units by 2023 with a CAGR (Compound Annual Growth Rate) of 1.9% for the period 2019-2023.
