By 2010, Gigabit Passive Optical Network (GPON) became the standard, offering speeds of up to 2.5Gbit/s. Over the next decade, GPON saw widespread deployment, meeting the growing demand for faster internet. However, as digital transformation accelerated, the need for higher speeds led to the introduction of 10G-PON in 2020. This technology, followed by XGS-PON, provided symmetrical 10Gbit/s capacity, enabling advanced applications like AI and big data analytics. By 2021, nearly 10 million 10G-PON OLT ports had been deployed globally.
The next leap came with the standardization of 50G PON in 2021. This technology addresses the exponential growth in data driven by IoT, cloud services, and emerging WiFi standards like WiFi7. It offers the multi-gigabit speeds that modern users demand, making it a critical step in the evolution of passive optical networks.
