In the list of gbic's you are to use for SMIP modules found here:
They say you can use DS-SFP-FCGE-SW. They call this a tri-rate GBIC, saying it can operate 1/2GB FC or 1GB Ethernet.
Is there anything really special about this GBIC? I mean, my experience is that just about any 1/2GB FC GBIC can run short haul fiber ethernet (850nm). I assume this is just marketing, or am I missing something? I just plugged in a rather generic FC gibc (agilent or finisar or the like) and I plugged it into a SMIP and could ping across just fine with no errors.
