Combo PON Has Become the Principal Solution for 10G GPON Construction
At present, more operators worldwide have carried out the 10G-GPON deployment and upgrade to meet the requirements of the gigabit user markets. In the global market, optical broadband access development has entered the Gigabit era. Combo PON is the mainstream large-scale commercial deployment solution for the upgrade of GPON to 10G GPON. This article will provide some knowledge about Combo PON. Combo PON Technical Implementation Combo PON is a combination of GPON and 10G GPON. It is a built-in optical multiplexing scheme that supports the coexistence of XGS-PON, XG-PON, and GPON ONUs. It is also called "three-rate Combo PON" and is recognized in the industry as the best solution for a smooth upgrade from GPON to XGS-PON. Because XGS-PON and GPON use different wavelengths, three-rate Combo PON multiplexes the two types of wavelengths in an optical module, thereby achieving separate transmission and reception of GPON and XGS-PON signals. The three-rate Combo PON optical mod
