Typical durability for a 10gb SFP+ fiber transceiver is around five to ten years under normal usage conditions.

The typical life of a 10gb SFP+ fiber transceiver is several years, but failures can vary widely depending on conditions. Most units last well beyond five years without issues, though some may begin to show problems around that time. Your experience suggests inconsistent performance—some devices fail quickly while others remain stable. Since you've already replaced one transceiver in the switch and are now seeing intermittent issues, it’s likely a single unit is failing rather than the entire setup. The fact that your servers have been working flawlessly for three years indicates the problem may be isolated to this particular NIC. Consider replacing with Twinax cables as a precaution, but monitor closely for further signs of degradation.
I've experienced some issues quickly and others lasting over five years without problems. The question seems to focus on whether you're using single mode or multi mode, and if in single mode you avoid long range optics (40km+ ones) since they might damage other components if the cable is too short.
For personal use, I've only experienced one issue with a DOA. Even my oldest devices, which are about four years old, still function perfectly. This setup is important to think about—especially if you're using it in a business or home environment, depending on where you get your components. The length of the DAC can become significantly more costly in such settings.
It seems like these items might not be lasting long due to poor quality. If they're getting hot too much, that could be the main issue. They should stay good for years if kept properly.
They are Dell PowerEdge servers equipped with Intel x710 NICs. Although only Intel transceivers are officially supported, we obtained units from FS.com previously (using a cloned vendor ID to mislead the NIC). There have been no issues before. This setup is widely used and stored in a secure data center. The environment is quite cold.
