  • What does XGS mean in optical modules

    What does XGS mean in optical modules

    A 10-gigabit-capable Symmetric Passive Optical Network (XGS-PON) is a next-generation passive optical network (PON) technology that offers much higher bandwidth than older systems. It's considered as the ideal solution to FTTx (especially FTTH) with its high bandwidth, great interoperability and manageability, high efficiency, etc, which gains more and more ISPs' favor. Optical fiber's greater transmission capacity and speed deliver upstream and downstream (symmetric) speeds of up to 10 Gbit/s (gigabits per second) on the road to connecting users in the last mile. It uses distinct wavelengths for downstream (1577 nm) and upstream (1270 nm) transmission, employing Time Division Multiplexing (TDM) and Time Division Multiple Access. XGS-PON is an updated standard for Passive Optical Networks (PON) that can support higher speed 10 Gbps symmetrical data transfer and is part of the family of standards known as Gigabit-capable PON, or G-PON. G-PON stands for Gigabit PON or 1 Gigabit PON. The “X” in XGS represents the number 10.
