We have purchased a lot through the Solid-Optics US team. Very happy with their pricing, reliability and support. We have their multi-fiber tool and have reprogrammed optics as needed to go between MFG equipment. I can only recommend that you give them a try.

So far I have found both https://www.flexoptix.net/en/flexbox-v3-transceiver-programmer.html and http://solid-optics.com/tools/multi-fiber-tool/so-multi-fiber-tool-id1768.ht... Is there anything else out there? Any opinions on these two companies? I believe they both require you to use their SFPs in order to program them, but I could be wrong.
