Questions & Answers

  • I am going to place a 1G BD connection. But I only have OM2. Can the module use om2?
    Pls noted that 1g bidi modules should be used with single-mode fiber, so you can't use om2.
  • I want to use Cisco compatible modules on ub switch, will it work?
    Generally, it will work well. We suggest you send us the model name of your UB switch to help us confirm the compatibility.
  • Can these bidi modules be used for short links (30...100 meters)?
    Yes. You can use the 10km bidi module for short links.

    I have bought 10G transceivers here in the past and they've always worked great. These are no exceptions. Highly recommended! Performs great between netgear GS716T and GS110TP.

  • Terry Dunlap United States of America

    I have been sourcing 1000BASE-BX BiDi SFP from QSFPTEK for resale since last year. Working with QSFPTEK for a long time let me know that the quality and price are really attractive. Also communicating with QSFPTEK for a long time, I learned that they already have high-end test centers from 1G to 100Gbps including Cisco, Juniper, Arista, Brocade. Talia told me that each of their optical modules is well tested before they leave the warehouse, which can guarantee their 100% performance, and, of course, I can guarantee my business and look forward to long-term cooperation with QSSFPTEK.

  • G. United States of America

    I Have 3 pairs of fiber between 2 buildings and one is damaged. I was looking for something like this and I found it. I can now split the pairs of fibers and use one strand for bi-directional data at full-duplex GB speed. They worked well after the one month test.
