How to easily assess Optical Received Power on all Force10 Ports with link present

The following article describes how to quickly and easily assess the optical receive power from any transceiver installed in any Force10 switch (C/E/Z/S-Series, MXL and IOA)
The following table shows the optical Min/Max (Optical budget) for SR (Short Reach) QSFP optical transceivers listed in the Dell Networking Optics & Cable Interop Matrix Spreadsheet:
 
 

Description	Value
Transmitter Output Wavelength (nm)	840 to 860 (850 nominal)
Receiver Input Wavelength (nm)	840 to 860
Transmit Output Power (dBm)	Max: 2.4 per lane
	Min: -7.6 per lane
Receive Input Power (dBm)	Max: 2.4 per lane
	Min: -9.5 per lane

 
 Below is the CLI command to show only ports that are linked up and the respective optical received power:



All optical measurements listed above are within the optical budget.
