Need help deciding which SFP transceiver for Cisco Catalyst 3560 series.

Couple questions.  First I have a Cisco Catalyst WS-C3560-24TS-E switch.  I'm using multi-mode fiber and wanted to know how I choose between the various transceiver options.  Also, I have a bunch of Dell 1000BASE-SX LC connector's.  Will these work for my Cisco.  If not, I think I narrowed my selection down to this Cisco part number, GLC-SX-MM, would this be correct?  Ideally I'd like to use the transceivers I have, but either way I need to find one to work with it.

    Accepted Solution

    The Dell Transceivers will not work.

    Yes, go with the GLC-SX-MMs for the Catalyst 3560s.  I've used hundreds of them, and for multi-mode fiber they are the only way to go.

    What transceiver would work if I wanted to plug more than one fiber strand into the port?

    The GLC-SX-MM uses an LC connector which takes 2 strands, 1 for transfer and 1 for receive... That goes with pretty much every fiber SFPs these days with exception to MTRJ and I believe some of the long haul stuff.
