As a new generation of Passive Optical Network (PON) technology, 25G PON and 50G PON have huge potential and development space. They provide higher data transmission speeds and greater bandwidth, which can meet the growing network needs in the future and promote the development and popularization of digital society.

As communication network are developing towards all-optical networks, optical Access networks will replace the copper wire access networks gradually. Due to rapid growth of high-speed data service and video service, fast reduction of fiber network construction cost, fierce competition among operator
