NS2 single board belongs to the line class single board, realizing the mutual conversion of the following signals: 8 x ODU0/4 x ODU1/1 x ODU2/2 x ODUflex1 x OTU2 or 1 x ODU2e1 x OTU2e. OTU2/OTU2e is the standard wavelength of DWDM in accordance with the ITU-T G.694.1 recommendation. Supports mixed transmission of ODU0, ODU1, and ODUflex.

TN11NS2/TN12NS2/TN52NS2/TN53NS2 Single Board Application Scenario 1: Realize the inter-conversion between 4-channel ODU1 signals and 1-channel OTU2 signals

Figure 1 Application scenario 1 of NS2 single board in WDM system

TN12NS2/TN52NS2/TN53NS2 single board Application Scenario 2: Realize the mutual conversion between 1 channel ODU2/ODU2e signal and 1 channel OTU2/OTU2e signal

For TN52NS2T04/TN52NS2T05/TN52NS2T06/TN52NS201M01/TN52NS201M02/TN53NS2:

• In "Standard Mode", when ODU time slot method is configured as "Auto Continuous", ODU0->ODU1->ODU2 is supported.

• In "Standard Mode", ODU0->ODU1->ODU2 are supported when "Auto Random" is configured for ODU time slot method.

• In "Compatible Mode", the configuration of ODU time slot mode is not supported, only ODU0->ODU1->ODU2 is supported.

TN52NS2/TN53NS2 single board application scenario 4: Realize the interconversion between 2 ODUflex signals and 1 OTU2 signal (only supported in OptiX OSN 8800).

Figure 4 NS2 single board application scenario 4 in WDM system

Description:

The total bandwidth of 2 ODUflex signals corresponding to 1 OTU2 optical signal cannot exceed 10Gbit/s.

Only TN52NS2T04/TN52NS2T05/TN52NS2T06/TN52NS201M01/TN52NS201M02/TN53NS2 support ODUflex in standard mode.

Application Scenario 5: Hybrid Transmission Scenario

Figure 5 NS2 single board in WDM system Application Scenario 5

Description:

The IN/OUT port supports mixed transmission of ODU0, ODU1 and ODUflex with a maximum bandwidth of 10Gbit/s.

Only TN52NS2T04/TN52NS2T05/TN52NS2T06/TN52NS201M01/TN52NS201M02/TN53NS2 support ODUflex in standard mode.
