TN53ND2 Is 2 Port 10G line service processing board
Huawei OSN 8800 OTN Line Board TN53ND2 Overview
ND2: 2 x 10G line service processing board
The available functional versions of the ND2 board are TN11, TN12, TN52, and TN53.
As a type of line board, the TN53ND2 board converts 16 ODU0, eight ODU1, four ODUflex, or two ODU2 into two ITU-T G.694.1 OTU2 signals or converts two ODU2e signals into two ITU-T G.694.1 OTU2e signals. The board supports hybrid transmission of the ODU0 service, ODU1 service, ODUflex service and the ODU2/ODU2e service.
The ND2 board is mainly used to achieve cross-connection at the electrical layer, and to provide OTN interfaces and ESC.
The ND2 board consists of the WDM-side optical module, signal processing module, control and communication module, and power supply module.
There are indicators and interfaces on the front panel of the ND2 board.
One slot houses one ND2 board.
The ND2 board is mainly used to achieve cross-connection at the electrical layer, and to provide OTN interfaces and ESC.
NO2 Specifications
The NO2 board carries out cross-connection at the electrical layer, and provides the OTN interfaces and ESC.
