FAQ about 200G QSFP56 FR4 Optical Transceiver
The QSFP56 200GFR4 CWDM4 1310 nm 2 km SMF transceiver supports reliable links up to 2 km over standard single-mode fiber (SMF) with forward error correction (FEC) enabled .
Digital Diagnostics Monitoring (DDM) provides real-time access to key operating parameters—such as optical output power, input power, temperature, laser bias current, and transceiver voltage—via an I²C interface, enabling proactive maintenance and link health visibility .
Yes. The 200GBASE-FR4 CWDM4 optical transceiver module is fully compliant with IEEE 802.3bs 200GBASE-FR4 and CWDM4 MSA specifications, ensuring seamless interoperability with any standards-compliant QSFP56 or QSFP-DD port.
MSA-compliant QSFP56 200G FR4 CWDM4 modules have been tested across leading vendor platforms (Arista, Cisco, Juniper, Mellanox, HPE, Dell, etc.) to guarantee 100% compatibility and zero-touch interoperability without any special coding.
This module uses duplex LC connectors on single-mode fiber (SMF), matching the CWDM4 wavelength plan (1271/1291/1311/1331 nm) for optimal medium-reach performance.
To interconnect hyperscale racks, install the CWDM4 QSFP56 module into QSFP56 ports on adjacent switches, run duplex LC SMF patch cords with CWDM MUX/DEMUX where needed, enable FEC on the host switch, and monitor link health via DDM—delivering up to 2 km reach at 200 Gb/s.
