Huawei OptiX OSN 9800 2 Port 100Gbit/s Universal Line Service Processing Board TNS2N402 Overview

TNS2N402: 2 x 100Gbit/s Universal Line Service Processing Board

The N402 board consists of an OTN processing module, VC cross-connect module, SDH processing module, WDM-side optical module, control and communication module, and power supply module.

The transmit and receive directions are defined in the signal flow of the N402 board. The transmit direction is defined as the direction from the backplane to the WDM side of the board, and the receive direction is defined as the reverse direction.

The following describes the signal flow in the transmit direction along with the module functions.

VC-4 signals and ODUk signals can be cross-connected through the backplane.

The VC-4 signals are received by the VC cross-connect module and sent to the SDH processing module for STM-N framing and OTN overhead processing. The generated STM-N signals are sent to the OTN processing module.

The ODUk signals are received by the ODUk cross-connect module and directly sent to the OTN processing module.

The OTN processing module maps the STM-N signals to the payload of appropriate ODUk signals, performs OTN framing and FEC encoding of the signals, and then produces and sends one OTU4 electrical signal to the WDM-side optical module.

The WDM-side optical module receives the OTU4 electrical signal from the OTN processing module, performs E/O conversion, and sends out one OTU4 optical signal over an ITU-T G.694.1-compliant wavelength through the OUT port.

The N402 board electrically regenerates one ITU-T G.694.1 compliant OTU4 optical signal.

The optical receiver on the WDM-side optical module receives one OTU4 optical signal through the IN optical interface and converts it into an OTU4 electrical signal.

The OTN processing module performs FEC decoding, overhead processing, and FEC encoding, which is the process of reshaping, regenerating, and retiming the OTU4 electrical signal and digitally wrapping it into an OTN frame.

The OTN-framed signal is sent to the optical transmitter on the WDM-side optical module. After performing E/O conversion, the transmitter produces and sends one ITU-T G.694.1 compliant OTU4 signal out the OUT optical interface.
