Third Party Transceivers for SFP+ Ports on an M590

BPL

I have a Firebox M590 with two SFP+ ports and according to the WatchGuard website, for multi-mode transceivers (10GBase-SR/1000Base-SX 850 nm), it supports the Cisco SFP-10G-SR. How particular is the M590 with requiring that exact model? I've seen Cisco variants of the same transceiver with model numbers like SFP-10G-SR-S and such. Will it accept those? More specifically, I can get MUCH cheaper third party transceivers that claim to be fully compatible such as the one I've listed below (TP-SFP-10G-SR). Can I safely use these third party transceivers in the M590?

The transceivers in this KB article are the ones we've tested. Many of the less expensive transceivers may work provided they are compatible with one of the listed models. We simply do not have the resources to test every revision of every SFP+ transceiver.

The only transceivers that support will help with are the ones listed in the KB article.

Can you plug them in to the firewall? Yes. As long as they're SFP/SFP+ they should fit.

Will they work if they're not listed? Maybe. If you want to do this, I'd suggest looking for ones that say they're compatible with ones that are listed.

Will support be able to help when the unsupported SFP+ module is dropping packets or not connecting at 2AM on a holiday weekend? We'll help identify the problem, but if it ends up being due to the transceiver, the only thing we can do is suggest you try supported ones.
