Application of CWDM boards on OSN 1800
In the case of a CWDM and DWDM hybrid network, the 1531 nm and 1551 nm wavelengths in the CWDM system must be reserved for the expansion to the DWDM system. The optical ports for the 1531 nm and 1551 nm wavelengths can be extended to access 10 and 16 DWDM wavelengths respectively. That is, a total of 26 DWDM wavelengths can be extended.

Whether an ND2 board can be used as the regeneration board for the LSX board
The WDM-side signals of the TN11LSX/TN12LSX board can be regenerated using another TN11LSXR board. The WDM-side signals of the TN13LSX/TN14LSX board can be regenerated using the TN12ND2/TN52ND2/TN53ND2/TN57ND2/TN55NO2/TN55NH2/TN53NQ2/TN54NQ2/TN57NQ2 board.

Whether the HBA board can be used together with the SFIU board
