H31-341_V2.5 · Question #412
The wavelength division system is configured with the 1st to 20th waves, and uses the NS4 single board. During the commissioning, the optical spectrum analyzer is used to test the M40 output port…
The correct answer is A. The insertion loss of the 20th channel corresponding to M40V is too large C. The light emission on the 20th wave OTU wavelength division side is too small D. The OTU center of the 20th wave is long-drifted. See the full explanation below for the reasoning.
Question
The wavelength division system is configured with the 1st to 20th waves, and uses the NS4 single board. During the commissioning, the optical spectrum analyzer is used to test the M40 output port. It is found that the optical power of the 20th wave is significantly lower than the other 19 waves. Which of the following are the possible reasons? (Multiple choice)
Options
- AThe insertion loss of the 20th channel corresponding to M40V is too large
- BThe RX port of the 20th wave OTU mistakenly added 5dB fixed optical attenuation
- CThe light emission on the 20th wave OTU wavelength division side is too small
- DThe OTU center of the 20th wave is long-drifted
