Fiber optic transceiver module BlueOptics QSB-512-BO 100000 Mbit/s QSFP28

The BlueOptics QSB-512-BO is a QSFP28 fiber optic transceiver module designed for 100000 Mbit/s optical links over multimode fiber. It supports bidirectional 100GBASE-SR2-Bidi operation with LC Duplex connections and implements MSA-compliant QSFP28 form factor. The module operates in the 832–918 nm wavelength range, provides Digital Diagnostics Monitoring (DDM/DOM) for real-time status of voltage, temperature and optical power, and is built to meet CE, FCC and RoHS requirements. With a reported MTBF of 3,000,000 hours and a compact silver housing, it is suitable for high-density switch, router and storage interfaces that accept QSFP28 transceivers.

Advantages

The module offers a high data rate of 100000 Mbit/s in a QSFP28 form factor while maintaining MSA compatibility for broad interoperability. Integrated DDM/DOM enables remote monitoring of key parameters such as supply voltage, laser current, transmit/receive power and temperature, which simplifies maintenance and fault finding. Built from industry-grade optical components and ICs, the transceiver is designed for long operational life and stable optical performance. Its bidirectional SR2 Bidi design reduces fiber cabling requirements by allowing transmit and receive signals over single fibers paired in an LC duplex connector.

How to use

Install the transceiver into a QSFP28 slot on a compatible switch, router, storage array or appliance according to the host vendor’s installation instructions. Connect LC duplex multimode fiber patch cables to the LC ports, ensuring correct pairing for bidirectional SR2 operation. If remote monitoring is required, enable DDM/DOM support in the host system and read diagnostic parameters through the device management interface. Handle the module by its housing and protect the optical interfaces with dust caps when not in use.

Recommendations

Verify compatibility with your specific hardware platform and firmware version before deployment. Use multimode fiber rated for 100G SR2 operation and keep fiber connectors clean to maintain signal quality. Ensure the host supports DDM/DOM to access diagnostic data. Observe ESD precautions during handling and follow manufacturer temperature and humidity limits for reliable long-term operation.
