Its all about support under warranty. CDW is selling the original Brocade SFP. The amazon links only shows a compatible one. In most cases it will work, but if that tiny metal piece will break your freshly installed 20-x2 linecard, Brocade may not replace it. Also some of the cheaper optics may not support monitoring or diagnostic options. You can also check the second market for an used original optic, if you want to save some budget.

Quick question for the experts.
Why when looking at SFPs, some sites list them as $800 when the same part number can be found on places like amazon for $30-$40. What is the difference in them? Why would I buy them from a place like CDW with what appears to be a 2,000% markup.
