could i T Transceiver connect to 100M Base-T ?

  • 1.  could i T Transceiver connect to 100M Base-T ?

    Posted Jul 18, 2020 09:01 AM

    I'm running the 5510 JH149A Switch.

    I want to connet to 100M Base-T 12port, so i have to use T transceiver(JD089B). but i just found the contents that support 1G and didn't find the contents that support 100M.


    5510 JH149A supports 100M SFP, so I think It will also support 100M Base-T. where can i find related data(document)?

    Interestingly, the old HP X125 1G SFP Transceivers QuickSpecs (22 March 2011, Edition 1) reports the JD089B as HP X125 1G SFP RJ45 Transceiver [*] and list it as capable of supporting only the IEEE 802.3ab (1000BASE-T) standard, that way it seems to imply no support for IEEE 802.3u (100BASE-TX) at least not listing it explicitly...but it could also be just a documentation error/oversight and the JD089B could be perfectly capable (on supporting Switches) to negotiate at 10Mbps (IEEE 802.3i 10BASE-T) or at 100Mbps (IEEE 802.3u 10BASE-TX) other than the expected 1Gbps (IEEE 802.3ab 1000BASE-T)...and it depends greatly by the switch port considered.


    [*] More recent documents list the JD089B as an HPE X120 1G SFP Transceiver instead.
