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

The BlueOptics QSFP-100G-SR4-MM850-BO is a QSFP28 fiber optic transceiver module engineered for short-reach 100 Gigabit Ethernet links over multimode fiber. The module supports a maximum data transfer rate of 100000 Mbit/s and a maximum link distance of up to 100 m using an MTP/MPO connector and 850 nm VCSEL optics. Housed in a metal enclosure and weighing approximately 40 g, the transceiver implements MSA-compliant QSFP28 electrical and mechanical interfaces and provides digital diagnostics for remote monitoring. With a reported MTBF of 1,000,000 hours, it is intended for high-availability network environments where compact, pluggable 100G optics are required.

Advantages

The transceiver offers industry-standard QSFP28 compatibility for straightforward integration into network switches, routers and storage systems that accept 100GBASE-SR4 optics. Its MTP/MPO multimode connector and 850 nm transmitter/receiver design enable simultaneous four-lane optical transmission for aggregate 100 Gbit/s throughput. The metal housing and tested component selection contribute to mechanical robustness and long operational lifetime, while the built-in Digital Diagnostic Monitoring (DDM/DOM) interface supplies real-time information on supply voltage, laser bias current, optical output/input power and temperature for easier maintenance.

How to use

Insert the QSFP-100G-SR4-MM850-BO transceiver into a compatible QSFP28 port on a switch, router or storage device while the host device is powered according to the vendor recommendations. Connect an appropriate MTP/MPO multimode fiber patch cord to the transceiver, ensuring the fiber type and polarity match the remote endpoint. Verify link status and, if required, query the module's digital diagnostics via the host system to confirm optical power levels, temperature and voltage. Follow the equipment manufacturer's guidance for hot-plugging procedures and firmware compatibility to ensure reliable operation.

Recommendations

Use OM3 or OM4 multimode fiber and matched MTP/MPO patch cords for best performance at 100 Gbit/s up to the specified distance. Confirm that the network equipment firmware supports third-party QSFP28 modules and enable DDM/DOM monitoring if available to assist with troubleshooting and preventive maintenance.
