Whether a TN53ND2 board can substitute for a TN12ND2 board on an OSN 8800

The K4XCT board can completely substitute for the K2XCT board on OSN 8800.

The 53ND2 board can substitute for the 12ND2 board but cannot substitute for the 11ND2 board.

The TN13OBU103 board can substitute for the TN11OBU103 board on OptiX OSN 6800. After the substitution, the TN13OBU103 board provides only the functions of the TN11OBU103 board, but the VOA is unavailable. Depending on the NE version and gain, the TN12OBU or TN13OBU board can substitute for the TN11OBU103 board so that the integration attenuation can be configured for the OBU.

The K4XCT board can completely substitute for the K2XCT board on an OSN 8800.

TN12ND2/TN52ND2 can be created as ND2 on the NMS to substitute TN11ND2. The board substitution does not require software upgrade. After the substitution, the board can function as TN11ND2 only. When both the transmit and receive boards use FEC encoding, they can substitute for each other. When both the transmit and receive boards use AFEC encoding, they cannot substitute for each other. The TN52ND2 board can substitute for the TN11ND2 board only when they use 800ps/nm-C band-tunable wavelength-(D)RZ-PIN optical modules.
