Description
This article describes the troubleshooting feature for when Small Form-Factor pluggable (SFP) transceivers are installed on the FortiGate showing vendor information, fiber type, temperature, voltage, and optical power.
Scope
FortiGate models that have SFP transceivers, or can accommodate SFP transceivers.
Solution
The general transceiver commands to retrieve information from all or a single interface:
get system interface transceiver
get system interface transceiver <interface>
For information about the affected interface status and counters, i.e., possible drops or errors.
diagnose hardware deviceinfo nic <interface>
show system interface <interface>
Note: In multi-VDOM environments, commands should be run under the 'config system global'.
Output Examples:
get system interface transceiver
Interface port1: SFP or QSFP transceiver is not detected.
Interface port2: SFP or QSFP transceiver is not detected.

During the troubleshooting process, it is good practice to make sure the transceivers and fiber cables are matched in single-mode or multimode. It is a single-mode transceiver; the fiber cable has to be single-mode. If the transceiver is in a multimode, the fiber cable has to be multimode.
