TNV3G220

TNV3G220 overview

The G220 board consists of a client-side optical module, signal processing module, control and communication module, and power supply module.

he G220 board electrically regenerates OTU2/OTU2e 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 OTU2/OTU2e electrical signals.

The OTN processing module performs FEC decoding, overhead processing, and FEC encoding, which is the process of reshaping, regenerating, and retiming the OTU2/OTU2e 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 OTU2/OTU2e optical signals carried over ITU-T G.694.1 compliant DWDM wavelengths out the TX optical interfaces.
