A certain wavelength division system is configured with the 1st to 20th waves, using the NS4 single board, and testing the M40 output port with a spectrum analyzer during commissioning. It is found that the optical power of the 20th wave is significantly lower than the other 19th waves.
What is the possible reason? ?

  1. The luminescence of the 20th wave on the LU WDM side is too small
  2. 20th wave LU center wavelength shift
  3. The insertion loss of the 20th channel corresponding to M40 is too large
  4. The RX error of the 20th wave of NS4 added 5DB fixed light attenuation

Answer(s): A,B,C
