Question
What is the main reason why the OSC monitoring signal does not pass through the EDFA amplification along with the business signal?
Options
- AThe rate of OSC is too low. If it is scaled up, the energy efficiency will be too low.
- BEven if OA fails, the OSC monitoring channel is still valid
- CPrevent monitoring signals from interfering with business signals.
- DThe power of the OSC is too low, below the amplification sensitivity of the OA.
