OSN9800 2x100 Gbit/s Line Service Processing Board
The OSN9800 N402 boards are available in the following functional versions: TNU1, TNU2, TNU3, TNU5, TNV1, TNV2, TNV3. The boards belong to the OTN line class of boards and realize the interconversion of the following signals: 160 x ODU0/80 x ODU1/20 x ODU2/20 x ODU2e/4 x ODU3/2 x ODU4/. 160 x ODUflex<->2 x OTU4. 160 x ODUflex<->2 x OTU4. OTU4 is a DWDM standard wavelength compliant with ITU-T G.694.1 recommendation. The same optical port supports mixed transmission of ODU0, ODU1, ODU2/ODU2e, ODU3, ODUflex.N402 adopts coherent reception technology and is applied in coherent systems. The single board supports functions and features such as electrical layer crossover, OTN interface, and ESC. The single board consists of WDM side optical module, signal processing module, control and communication module, and power module.
Attention:
Single boards using different optical line code types cannot be docked, for example, QPSK, QPSK wDCM, QPSK wDCM-Enhanced are different code types, T51 uses QPSK, T61 uses QPSK wDCM, and they cannot be docked;
T6x supports AFEC level configurable, docking is supported only when the AFEC level is configured to be the same at both ends.The transmission distance of T6x is compared as follows: T61>T62>T65, and the actual transmission distance is based on the shorter one after docking of different veneers;
Single boards with different error correction codes cannot be docked. HFEC, SDFEC, SDFEC2, etc. are different error correction codes.
Functions and Features
The OSN9800 N402 single board supports functions and features such as layer crossing, OTN interface, ESC, etc. The N402 single board supports line mode and trunk mode. The functions and features of line mode and trunk mode are shown in Table 1 and Table 2, respectively.
