1m) high, but taller options are available if you need to accommodate more servers. Depth: Server rack depth, meaning the distance between the front and back of the cabinet, can affect how large each server can be. A server rack is more than just a physical frame—it determines how well your rack servers, network switches, PDUs, and storage arrays can be organized, cooled, and maintained. Common server rack sizes are 19‑inch width, heights like 42U or 48U, and depths from ~24″ to 48″. Whether you're upgrading a small server room in the Philippines, expanding a data hub in Spain, or setting up your first network cabinet in Uzbekistan.

The "X" in XGS represents the number 10, and the letter "S" stands for symmetrical, XGS-PON = 10 Gigabit Symmetrical PON. GPON (Gigabit-capable Passive Optical Network) is the access technology of a passive optical network (PON) based on the ITU-T G. Its development has undergone continuous evolution and improvement, while also driving the development and popularization of fiber optic access networks. 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.
