• A.FALSE
• B.TRUE

The ODU product label is shown in the picture. Which of the following statements is correct? (multiple choice).

• A.The receiving frequency range is: 7582-7638MHz
• B.This ODU can be used as low station
• C.The transceiver interval of this ODU is 154MHz

The insertion loss of the 40 sub-wavelength channels of D40 is 6dB, regardless of the influence of noise, when the signal is full-wave, the IN port optical power of D40 is X dBm. If the optical power of the IN port is reduced by 1dB, The measured value is () dBm. (Assuming that the optical power of each channel is balanced, lg40=1.6)

• A.(X-22)
• B.(X-6)
• C.(X-23)
• D.(X-5)
