    • What does QSFP112 mean?
      A 400G QSFP uses 4 x 100Gb/s PAM-4 elec lanes. "112" refers to the the max data rate (112Gb/s) each electrical interface can handle.
    • Can I use the QSFP112 optical transceivers in OSFP switches?
      You cannot directly use QSFP112 module in OSFP switch, because QSFP112 and OSFP are physically different, incompatible form factors.
    • Can 400G QSFP112 SR4 module be used as 200G?
      Yes, it can be used as 200G module.
