I have a Cisco Nexus 3548 switch and a bunch of machine that I want to connect to it via 10GbE RJ45 connectivity. I am a bit overwhelmed with all the acronyms and sheer volume of technical info on this. I know what I want looks like this: http://www.amazon.com/10Gtek%C2%AE-Compatible-Gigabit-Transceiver-Mini-GBIC/dp/B00U77IJ2M/ref=sr_1_1?ie=UTF8&qid=1449775858&sr=8-1-spons&keywords=cisco+sfp%2B+rj45&psc=1

But this is only 1GbE. Is there such a thing for 10GbE?

  • This Cisco 10 Gb transceiver modules was updated today. I don't see any UTP. cisco.com/c/en/us/td/docs/interfaces_modules/…

Sorry to tell you that few fiber optic manufacturers and suppliers update 10G copper transceiver modules. You can choose 10GbE fiber connectivity or 10G SFP+ DAC for connectivity. Then the choice would be much wider. Hope the following link helps you. https://www.linkedin.com/pulse/10gbe-interconnect-solutions-overview-fern-xu?trk=mp-reader-card

  • I faced this same problem. My conclusion is that PHY module is big enough to doesn't fit in SFP+ space. So, you'll never see a 10GBaseT SFP+ Module. As @katiesi said, your only option for cupper is DAC (aka twinax) cables.

Unfortunately 10GBASE-T was more power hungry than 1000BASE-T. As a result of this SFP+ manufacturers were not initially able to offer a 10GBASE-T option. This has left an awkward situation with regards to 10 gigabit interoperability.

However it seems things are starting to change. 10GBASE-T SFP+ transcievers are starting to appear albiet with a 30m distance limitation. Prolabs claim to have a cisco compatible 10GBASE-T SFP+ but their website gives no indication of price.
