TN54NS3T03 Is Huawei OptiX OSN 8800 OTN Line Board
            Huawei OptiX OSN 8800 OTN Line Board TN54NS3T03 03030LWQ Overview
NS3: 40G line service processing board
The available functional versions of the NS3 board are TN11, TN52, TN54, TN55, and TN56.
As a type of line board, the NS3 board converts 32 ODU0, 32 ODUflex, 16 ODU1, four ODU2, or one ODU3 into one ITU-T G.694.1 OTU3 signal or converts four ODU2e into one ITU-T G.694.1 OTU3e signal or converts 256 VC-4 signals into one OTU3 signal. The TN52NS3/TN54NS3/TN55NS3 board supports hybrid transmission of the ODU0 service, ODU1 service, and the ODU2/ODU2e service. The TN56NS3 board supports hybrid transmission of the ODU0 service, ODU1 service, ODU2/ODU2e service, ODUflex service and the VC-4 service. The TN55NS3/TN56NS3 board uses coherent receive technology. Therefore, the board is intended for coherent systems.
The NS3 board achieves cross-connection at the electrical layer, and to provide OTN interfaces and ESC. The TN56NS3 board supports hybrid transmission of OTN and SDH services.
The NS3 board consists of the WDM-side optical module, signal processing module, 1588v2 module, control and communication module, and power supply module.
Functions and Features of the TN54NS3T03 Board
| 
			 Function and feature  | 
			
			 Description  | 
		
| 
			 Basic function  | 
			
			 NS3 converts signals as follows: 
 The TN52NS3/TN54NS3/TN55NS3 board supports hybrid transmission of ODU0/ODU1/ODU2/ODU2e signals. The TN56NS3 board supports hybrid transmission of ODU0/ODU1/ODU2/ODU2e/ODUflex/VC-4 signals. When the mixed signals contain an ODU2e signal, they must be mapped into an OTU3e signal. The TN11NS3/TN52NS3/TN54NS3 board supports dispersion compensation for signals received on the WDM side.  |
