Latest Patents
One of Alain Granger's latest patents is the "DWDM and CWDM hybrid PON system and method." This invention describes a passive optical network (PON) that includes an Optical Line Termination (OLT), an Optical Distribution Network (ODN), and multiple Optical Network Terminations (ONTs). The OLT features a Dense Wavelength Division Multiplexing (DWDM) multiplexer and a CWDM demultiplexer, which are coupled to a Wavelength Division Multiplexing (WDM) filter. The ODN is designed with a WDM filter, a DWDM demultiplexer, and several fanout splitters, allowing for efficient data transmission across the network.
Another significant patent is related to "Passive optical network optical time-domain reflectometry." This invention enhances troubleshooting capabilities of a PON by deploying cascaded splitters, some of which have multiple inputs. This allows for direct coupling to an Optical Time-Domain Reflectometer (OTDR), enabling precise optical time-delay reflectometry on selected segments of the PON.
