For the wavelength division system, configure the 1st-20th wave, use the NS4 single board, and test the M40 output port with the spectrum analyzer during the commissioning. It is found that the optical power of the 20th wave is significantly lower than the other 19 waves. The possible reasons are as follows: (Multiple Choice)

• A.The 20th wave OTU's RX port is incorrectly added with 5dB fixed light decay.
• B.The 20th wave OTU center is long drifted
• C.The 20th channel corresponding to the M40V has a large insertion loss.
• D.The 20th wave OTU wave side light is too small
