Questions & Answers

  • Can I plug an OSFP optical module to a QSFP-DD port?
    No. QSFP-DD and OSFP are two different form factors and they have completely different shapes and sizes. You can only use one kind of form factor in the corresponding system, for example, if you use OSFP system, then you must use OSFP transceiver and cable.
  • Can I plug a QSFP28 optical module to a OSFP port?
    Yes, but you need to use an adapter. When inserting a QSFP28 module into an OSFP port, the OSFP port must be configured for 100G instead of 400G transmission rate
  • What 400G form-factors does QSFPTEK support?
    QSFPTEK support OSFP and QSFP-DD form factor. QSFPTEK 400G platform can offer OSFP and QSFP-DD variants, OSFP form factor include OSFP-400G-LR8, OSFP-400G-DR4, OSFP-400G-SR8, QSFP-DD form factor include QSFP-DD-DR4, QSFP-DD-FR4, QSFP-DD-SR8, QSFP-DD-LR8, QSFP-DD-ER8, QSFP-DD-4x100G-LR.

  • Griffith Huggins United States of America

    I asked a lot of questions during the purchase process, because my customer's delivery time was involved, and they shipped quickly. I bought an extra one and tested it. The result is that the performance is very good, and it is compatible with my switch.
