Huawei OptiX OSN 8800 PID NPO2E Board TN55NPO2EL02

NPO2E: 10G PID line service processing board, 20–channel extended

The available functional version of the NPO2E board is TN55.

As a PID board, the NPO2E board performs conversion between 64 x ODU0, 32 x ODU1, or 8 x ODU2 signals that are cross-connected through the backplane and 8 x OTU2 optical signals over standard wavelengths for a WDM system, between 8 x ODU2e signals and 8 x OTU2e optical signals over standard wavelengths for a WDM system. In addition, the NPO2E board receives four OTU2/OTU2e signals from the ENQ2 board through the backplane. Then the NPO2E board multiplexes the four OTU2/OTU2e signals with its own eight OTU2/OTU2e signals into one optical signal for output. Inside the NPO2E board, there is a red/blue band filter, which converges 12 x OTU2/OTU2e signals output by the local NPO2E board and 8 x OTU2/OTU2e signals output by another NPO2 board into one channel of optical signals for output. It also performs the reverse conversion. In addition, the NPO2E board supports hybrid transmission of ODU0, ODU1, and ODU2/ODU2e signals.

The NPO2E provides functions and features such as OTN interfaces and ESC.

There are four indicators, optical interfaces, laser level label, and PQ2 sub-board on the front panel of the NPO2E.

The NPO2E occupies two slots.
