Hisense Broadband compatible LMQ3926-PC+ Description
The EDGE 400G-QSFP-DD-2.1 is a direct replacement for the Hisense Broadband LMQ3926-PC+ 400GBASE-FR4 QSFP-DD module. Hisense Broadband is an OEM transceiver manufacturer whose modules ship as factory-installed optics by equipment vendors. Same duplex LC connector, same 2km single-mode reach.
The module transmits on four CWDM wavelengths (1271, 1291, 1311, 1331nm) using PAM4 modulation at 53.125 GBaud per lane for a 400 Gb/s aggregate data rate. An internal DSP performs gearbox adaptation between the electrical host interface and the four optical lanes. Rated for a 4dB maximum optical link budget, supporting 2km over OS2 single-mode fiber. Operating temperature 0 to 70°C.
LMQ3926-PC+ modules may appear in equipment from vendors that source factory optics from Hisense Broadband. If your switch identifies the installed module as LMQ3926-PC+ via the EEPROM vendor field, the EDGE 400G-QSFP-DD-2.1 is the compatible replacement.
The module conforms to IEEE 802.3cu for the 400GBASE-FR4 optical interface. Diagnostic monitoring via CMIS provides real-time per-channel transmit and receive power, temperature, voltage, and bias current through your platform management interface.
