TNU1G404

TNU1G404 overview

The G404 board electrically regenerates OTU4 optical signals carried over ITU-T G.694.1 compliant DWDM wavelengths.

The optical receiver on the WDM-side optical module receives OTU4 optical signals through the RX optical interfaces and converts them into OTU4 electrical signals.

The OTN processing module performs FEC decoding, overhead processing, and FEC encoding, which is the process of reshaping, regenerating, and retiming the OTU4 electrical signals and digitally wrapping them into OTN frames.

The OTN-framed OTU4 electrical signals are sent to the optical transmitter on the WDM-side optical module. After performing E/O conversion, the transmitter produces and sends OTU4 optical signals carried over ITU-T G.694.1 compliant DWDM wavelengths out the TX optical interfaces.
