Ok then I'll search them.. Thanks..
Just want to know, is there any explanation there in the service manual about how the microprocessor do so OTDR can get the graphic?
Actually I'm already read some literatures, but some of them are just telling that OTDR works based on Rayleigh Scattering and Fresnel Reflection.
And not very clear of how the microprocessor convert the bits produced by ADC to dB that shown in the OTDR graphic.
And for the service manual for...
Hello all, I want to ask,
1. What does a microprocessor contained in the OTDR do?
2. How can OTDR get the graph dB vs km?
3. Is it true that the microprocessor do logarithmic function? 20 log (Va / Vb), with Va is the present voltage and Vb is the voltage before?
4. If the OTDR do logarithmic...
Hello all, want to ask.
1. What is the used of microprocessor at OTDR? And please be spesific.
2. How can the OTDR shows the graphic dB vs km as the result?
Because as I know, the backscatter and reflected pulse that detected by Avalanche Photodiode is changed to current, then the current is...
