How compatible are sfp modules between devices. For example, am I likely to be able to plug something like this into a cisco, hp, or other switch with mini gbic ports? http://www.cdwg.com/shop/products/default.aspx?EDC=1278641

I have been asked the question many times in my technical support role at Netwerks UK. If a device requires coded SFP modules (i.e. Cisco / HP) then you need either the OEM module or a compatible version. If the device does not require coded SFP (i.e. Netgear) then you can use any SFP, even a Cisco.

Please see this document regarding the compatibility of SFP's and also a FAQ I put together in an attempt to straighten out some of the confusion on this topic.

Actually, on Cisco gear you can disable the need for coded SFPs. Good luck getting support in that config, but you can do it. –  MDMarra Sep 14 '12 at 21:02
    
n.b On Cisco platforms the command "service unsupported-transceiver" is generally available in NxOS and IOS versions. The command won't autocomplete and, as is implied, it is unsupported but allows the use of 3rd party optics. –  rnxrx Sep 15 '12 at 0:37
