The QSFP28 100GBASE-LR4 module is designed for data transmission using two single-mode (SM) fibers. It transmits data at speeds of up to 100 Gbps, over distances of up to 10 km. Our Compatible RAD QSFP28-1D-DML QSFP28 transceiver is based on our 100G-QSFP28-10 product, which has the same parameters and is manufactured in accordance with the same industry standards as its OEM counterpart. Shorter reaches typically utilize Vertical Cavity Surface Emitting Lasers (VCSELs), while longer reaches rely on Electro-absorption modulated lasers (EMLs) or Directly. The INTCERA 100G QSFP28 LR4 DML 10km optical transceiver (GQS-SPO101-LR4CB) is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802. To obtain a detailed certification certificate, please go to the product compliance. Among these optical modules connecting 100G links, 100G QSFP28 is the first choice because of its small size and low power consumption.
