QSFP+28SR4-BO network transceiver module BlueOptics 100000 Mbit/s

The BlueOptics QSFP+28SR4-BO network transceiver module is a compact fiber optic module designed for 100000 Mbit/s data links. With a QSFP28 interface and MPO/MTP multimode fiber connection, it implements the 100GBASE-SR4 standard using 850 nm transmit and receive wavelengths. The module’s small form factor, silver finish and 40 g weight make it suitable for dense data center and enterprise network environments where space and power efficiency matter. A reported MTBF of 3,000,000 hours indicates an emphasis on long-term operational reliability.

Advantages

The module supports high-bandwidth aggregation and short-reach multi-lane transmission while maintaining compatibility with MSA-compliant QSFP28 ports and MPO/MTP cabling. Its 850 nm transmitter and receiver pair is optimized for multimode fiber systems, providing predictable optical performance for 100GBASE-SR4 links. The compact QSFP28 form factor allows easy insertion into compatible switches, routers and other network hardware, and the low weight reduces mechanical strain on connectors and cages.

How to use

Install the BlueOptics QSFP+28SR4-BO into a compatible QSFP28 slot on your switch, router or other network device while the host port is powered down or following the vendor’s hot-plug instructions. Connect an MPO/MTP multimode fiber cable to the transceiver, ensuring proper polarity and that the cable and port support the 100GBASE-SR4 multimode profile. Monitor link status through the host device management interface and verify optical parameters such as receive power and lane alignment to confirm proper operation.

Recommendations

Use multimode fiber with the appropriate OM grade (OM3/OM4) for reliable 100GBASE-SR4 performance and maintain clean fiber connectors to prevent signal loss. Validate compatibility with the specific network hardware platform prior to deployment, and follow ESD handling and manufacturer guidelines when installing or removing the transceiver.
