質問 # 26
After a device is powered on, what need to be checked on subrack fans? (Choose all that apply.)
- A. The PWR indicator on the subrack is steady on.
- B. The FAN indicator on the fan tray assembly is steady green.
- C. The fans have been started.
- D. The airflows through the upper and lower parts of the subrack.
正解：B、C、D
解説：
After powering on, ensure the fan tray's FAN indicator shows steady green (normal operation), fans are spinning properly, and airflow through both upper and lower parts of the subrack is unobstructed to maintain adequate cooling.
質問 # 27
For a 100 Gbit/s signal, the baud rate of the data is actually 25 Gbaud/s (100 ÷ 2 ÷ 2=25).
- A. True
- B. False
正解：A
解説：
For a 100 Gbit/s signal using PAM4 modulation, each symbol carries 2 bits, effectively halving the baud rate compared to the bit rate. Additionally, using dual polarization halves the required baud rate again. Therefore, the calculation 100 ÷ 2 ÷ 2 = 25 Gbaud/s is correct.
質問 # 28
Which of the following are not 400G transmission modulation technologies?
- A. FDDM/Nyquist Spectrum Compression Technology
- B. Advanced oDSP algorithm
- C. Higher order modulation (xQAM)
- D. Multicarrier Generation and Multiplexing
正解：B
質問 # 29
