Which PON does Flex-PON support?

TheFlex-PON boardsupports multiple PON technologies, including: GPON:Gigabit Passive Optical Network, widely used for residential and small business applications. XG-PON:10G Asymmetric Passive Optical Network, offering higher upstream and downstream bandwidths. XGS-PON:10G Symmetric Passive Optical Network, providing equal upstream and downstream speeds. Combo PON:Combines GPON and XG(S)-PON on the same port, enabling seamless upgrades from GPON to XG(S)-PON without replacing hardware. The only option not supported by Flex-PON isXG-PON Combo, as "Combo" typically refers to the integration of GPON and XG(S)-PON, not just XG-PON alone.
