Must have if you have 1gbe spf compatibility issues. I recommend this product to anyone seeking a compatible transceiver solution.

It plugged in and instantly came up. No issues at all. Wouldn't hesitate to order more.

Seems to work without issue in Cisco switches. It works and doesn't cost a fortune. Gets a bit warm but all of them do.

I installed it without encountering any problems. The only drawback is that it runs a bit hot, but that seems to be the case with all the other transceivers I've used as well.

This pace is something that I am not used to at all. Fingers crossed that the mighty engineers will be satisfied and then we can do pretty things with FS goods here.
If there is a satisfactory survey about customer care, I would like to give you 5 stars (out of five).

The new SFPs from August 19 are absolutely amazing. The very best I have ever worked with.
