Instructions
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:
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.
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.
