Link performance through OSNR

Hello, dear!

It's nice to meet you in the community.

We're working on your problem. Just a moment, please.

Hi there! 

You can use the OD system on the U2000 or NCE to detect the OSNR of optical wavelength signals.

The Optical Doctor System - No. 9

Optical doctor OSNR

Thank you!

The OSNR is the ratio of the signal to the noise so it gives indication of the quality of the signal .

- The higher the OSNR the better the signal.

- The OTU and line boards have limit to recognize the signal some boards can recognize the signal if signal to noise ratio is 20 and some to 14 or 13 , According to the modulation used and the line code and signal rate.

Hello.
You can get the OSNR using the OPM board
or OSA (optical spectrum analyzer) device which you can move to sites and check along the way point by point.
