QSFP Transceiver Module BlueOptics QSFP-100G-SR4-MM850-CM-BO 100000 Mbit/s

The BlueOptics QSFP-100G-SR4-MM850-CM-BO is a QSFP28 fiber optic transceiver module engineered for 100 Gbit/s optical links over multimode fiber. Housed in metal and finished in silver, the module uses LC termination via an MPO/MTP interface and supports short-range 100GBASE-SR4 optical transmission up to 100 meters on suitable multimode fiber. The compact unit weighs 40 g and provides a standardized form factor for integration into switches, routers and other network hardware that accept QSFP28 modules.

Advantages

This transceiver supports full 100 Gbit/s data rates and adheres to MSA-compatible QSFP28 specifications for interoperability with compliant equipment. The module offers integrated digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, optical transmit power, receive power and temperature. Metal housing improves mechanical robustness and thermal performance. Tested compatibility with major hardware platforms ensures consistent operation when installed in devices that support SR4 QSFP28 modules.

How to use

Install the QSFP-100G-SR4-MM850-CM-BO into a compatible QSFP28 slot in powered-down or hot-pluggable equipment following the host vendor’s instructions. Connect the module to a matching MPO/MTP multimode fiber patchcord or patch panel that routes to LC-terminated ports as required by your cabling plan. Verify link status and diagnostics through the host device’s management interface to confirm proper optical power levels and module temperature. Ensure fiber polarity and patchcord type match the SR4 mapping for correct transmit/receive alignment.

Recommendations

Use OM3/OM4 multimode fiber for optimal reach and performance at 100 Gbit/s, and follow EIA/TIA and vendor cabling guidelines. Confirm that the network hardware supports SR4 QSFP28 modules and DDM if diagnostic monitoring is required. Avoid bending or contaminating fiber connectors; clean endfaces before mating and secure patchcords to minimize stress on the transceiver. For critical links, record DDM values after installation and schedule periodic optical checks to detect degradation early.
