[AusNOG] Cisco Compatible SFP's

Wed Jun 28 15:23:38 AEST 2023

Hi Mitch,

It also comes down to QC and general manufacturing tolerances. You see vendor optics fail, you see third party optics fail, regardless of the hardware in use. As Tim pointed out, quality and cost are usually interlinked.

Mark is highlighting that entire, large batches of FS optics have had major problems and he has had no support from the supplier. That doesn't sound like a hardware issue if you replace the optic with a different vendor and all of the issues disappear.

Regards,
Louis

Hi Mark,

That sounds more like a Equipment issue rather than the SFP's Perhaps just compatibility or power regulation to the SFP. Having 4 SFP's Fail at the same time is highly unlikely even if they are FS. SFP's are Pretty basic devices with a simple IC, generally a PIC for the ID and Optical Driver IC's. There isnt much that can fail.

Ive used Codecom, FS and Genuine and have only had a handful of issues (Usually with the Genuine), Most of the issues being Equipment rather than the SFP itself.

It’s less a case of 1-in-a-million and more about statistical likelihood of failure.

Cheaper price = lower quality, it’s a case of when not if you’ll encounter a failure and if that’s acceptable to your business.
If you’re prepared to have spares, prepared to see a link fail and can have it replaced in a reasonable time, that’s an acceptable risk.
If any of the above isn’t acceptable, you make a more reliable choice.
