Product Q&A

Q:What is the transmission distance of the 400G QSFP-DD FR4 module?

A: The QSFP-DD FR4 optical transceiver supports up to 2km transmission over single-mode fiber, making it suitable for data center interconnect and enterprise network links requiring medium-distance 400G connectivity.

Q:How does the CWDM technology work in this FR4 transceiver?

A: The module uses four CWDM optical lanes with MUX/DEMUX technology. Each wavelength carries a portion of the 400G signal, and the four channels are combined onto a duplex fiber connection to achieve high-bandwidth transmission with reduced cabling complexity.

Q:What fiber cabling is required for this QSFP-DD FR4 module?

A: The module is designed for single-mode fiber (SMF) infrastructure and typically uses duplex LC connectors, allowing compatibility with existing long-reach data center and enterprise fiber networks.
