Hi I am trying to connection a fibre across to an older set of switches [Dell &HP] that run SFP 1G and looking for any ideas on the SFP to use in the TP-link. Equipment is already 850nm on other devices. I have seen other posts advising that the SFP+ port can run at slower speeds but not sure if this requires a SFP at 1G at each end or a SFP+ in the tp-links that can select slower speeds. Any recommendations on the SFP or SFP+ appreciated. I have tried an

 

Intel E1/10GSFPSR Compatible Dual-Rate 1000BASE-SX and 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC MMF Optical Transceiver Module in TP-link but does not seem to want to connect. Similarly a pair of SFP's that work between the current switches.

 

Any advice appreciated or advice if it is this configuration that is not possible.

Thanks

Chris

  @Chirs Thanks for the insights. I managed to change port speed and the SFP's are now functional. I probably expected auto speed selection but it has to be manually set and once configured, links are up and running. Remember that the SFP port may be up and that spanning tree may stop data flow if you have loops in your network. Just by way of things to keep in mind. Thanks again.
