What are some of the common and important questions that i should expect in optical transmission interview? And please give some answers too. Thanks
Here are a few questions and answers you can expect in a fiber transmission role technical interview:
What are the devices used in Optical Network Maintenance & Diagnosis?
PDH/SDH analyzer
Used to measure jitter and not error ratio, also can be used as a test signal source.
What is the Optical Spectrum Analyzer?
Used to measure optical signal-to-noise ratio and central wavelength.
What is the Multi-Wavelength Meter?
Check the central wavelength and wavelength deviation.
What is the Optical Power meter?
Measure power values with a wide range.
What is the Tunable Laser Source?
Used to provide test optical signals with multiple wavelengths.
What is the Tunable Attenuator?
Added to the line to suppress high power and protect the board from damage by higher levels of power.
