310 nm upstream and 490 nm downstream PON WWDM devices are used inside the PON for facilitating the transport of downstream traffic from the central office (CO) optical line terminal (OLT) with the upstream signal from the optical network unit (ONU) installed at the premises They can also be used to combine and separate the downstream and upstream traffic at the customer for the ONU with individual transmitters and receivers as optical network terminals (ONT) These multiplex and demultiplex the voice and data similar to Figure B.1: – 310 nm channel for Data/Voice upstream – 490 nm
