What is XGS PON 10G Broadband
What is XGS-PON?
XGS-PON (ITU Standard G.9807.1) is an updated standard for Passive Optical Networks (PON) that can support 10 Gbps symmetrical data transfer (the same transmission speeds up and downstream) and is part of the family of standards known as Gigabit-capable PON, or G-PON. The “X” in XGS represents the number 10, and the letter “S” stands for symmetrical. XGS-PON = 10 Gigabit Symmetrical PON. An earlier, asymmetrical 10 Gigabit PON version (XG-PON) was limited to 2.5 Gbps in the upstream direction.
PON technology has been around for a long time and has continued to develop through multiple iterations with differing wavelengths, speeds, and components emerging as the technology has improved. The common denominator of all fiber optic PON networks remains the unpowered or passive state of the fiber and its splitting or combining components; for example, no active elements such as optical amplifiers, which would require power, are present in the network. With streaming, high definition, 5G, and other emerging technologies continually pushing bandwidth demands, developing XGS-PON and other standards has proven essential.
Unlike GPON, which supports AES encryption only in the downstream direction, XGS-PON also supports its encryption in both the upstream and downstream directions. While AES encryption is optional, it is essential for secure data transmissions.
