The transceiver consists of two sections: The transmitter section incorporates four CWDM DFB lasers. And the receiver section consists of a PIN photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8636 which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage.


  • Easy to Use- Easy installation, plug and play, fully hot-pluggable. Widely used in fiber switches, routers, NIC, servers or other fiber optic equipments with 100Gb QSFP28 ports.
  • Superior DDM Function- DDM allows you to monitor the critical information concerning the status of the transmitted and received signals of the transceivers in real-time to find out potential problems.


  • Compliant with IEEE 802.3ba, IEEE 802.3bm, 100G CDWM4 MSA, QSFP MSA, SFF-8665, SFF-8636 standards
