Yup, they are basically the same, but... Cisco SFP(+)'s have an proprietary ID on the chipset that the switch/router detects, and without which the SFP(+) will NOT work unless you use a secret command[1]. And as you see by the prices, I'll bet you can guess why. (Cisco would say it's a QA/supportability thing, I call BS.)
I like Finisar for SFP's; I believe they are the OEM for Cisco's SFPs. Never had a problem with them.

Does anyone have any experience using SFPs from third-party vendors in a Cisco environment? Having recently spent $500 a whack for brand new genuine Cisco 10Gb modules (SFP-10G-SR in this case) I was pretty shocked to see 'compatible' SFPs of the same type under twenty bucks online. Don't know if I'd trust those in particular, but there are plenty of choices for well under $100. They're so cheap by comparison I'm tempted to just try a couple, but I thought I'd see if anyone on the list had any particularly good or bad experiences with any vendor.
