¿µ¹®³»¿ë¿ä¾à This standard defines further wavelength ranges reserved for additional service signals to be overlaid via WDM in future PONs whose wavelength allocations are based on ITU-T recommendation G.983.3. For this purpose, this recommendation defines and provides;
- Wavelength ranges to be reserved
- X/S tolerance in PON optical network units (ONUs)
- Sample parameters of a discrete WDM filter that combines and isolates the G-PON up/down signals and enhancement bands at the OLT side
- Examples of wavelength allocation for NGA services and video distribution services
