Questions & Answers

  • Is the 1G SFP transceiver compliant with the 10G switch?
    If needed, you can do that, with a link rate of 1G.
  • Is this 1G SFP module tested for compatibility?
    Yes, our modules are rigorously tested before selling and you can also download the test reports here: https://www.qsfptek.com/test-center.html.
  • I notice that the 1G LX/LH supports both SMF and MMF. So what's the diffrence?
    If you use MMF cables like OM2/OM3/OM4, the max diatance is 550m. If you use SMF cables, it can reach up to 10km. So you can choose cable type according to your application.
