Wavelength of GPON device
BPON, EPON, GEPON, and GPON have the same basic wavelength plan and use the 1490 nanometer (nm) wavelength for downstream traffic and 1310 nm wavelength for upstream traffic. 1550 nm is reserved for optional overlay services, typically RF (analog) video. 984 Gigabit-capable Passive Optical Networks (GPON, G-PON) standard, first defined in 2003,. Asterfusion's GPON solution combines GPON OLT Stick SFP modules with SONiC-based open switches, creating a flexible, scalable, and cost-efficient all-optical access network that can be centrally managed through an OpenWiFi-compatible controller—making it ideal for campuses and small-to-medium. How It Works: A central Optical Line Terminal (OLT) connects to many homes and businesses through passive splitters and Optical Network Terminals (ONTs).
