Whether E2OBU03 can substitute for E2OBU01
Query the performance counters of boards: E2OBU01: C-band optical power amplifier with 20 dB gain E2OBU03: C-band optical power amplifier with 23 dB gain According to the product documentation, the following conclusions are drawn: 1. E2OBU03 can substitute for E2OBU01. E2OBU03 actually has slightly larger noise than E2OBU01, but the small difference does not affect the system and therefore can be ignored. That is why E3 series amplifiers retain only 0BU03 and OBU05 rather than OBU01. 2. For E2OBU01, the gain is 20 dB and the single-wavelength nominal input optical power in a 40-wavelength system is �?6 dBm. For E2OBU03, the gain is 23 dB and the single-wavelength nominal input optical power in a 40-wavelength system is �?9 dBm. When E2OBU03 substitutes for E2OBU01, ensure that the single-wavelength nominal input optical power of E2OBU03 is 3 dB lower than that of E2OBU01. After board substitution, the input optical power values of the OBU boards must be adjusted to appropriate values.

Whether TN52ND2 can substitute for TN12ND2
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.

Whether OBU103 can temporarily substitute OAU101
The two boards cannot be directly substituted. If OBU103 needs to be inserted to another slot for substitution, the optical power must be adjusted because the gain and single-wavelength nominal values of the two boards are different.

Whether the TN13OAU103 board can substitute for the TN12OAU103 board
The TN13OAU103 board can substitute for the TN12OAU103 board.
