Glasvezel-transceiver BlueOptics QSB-522-BO 100000 Mbit/s QSFP28

The BlueOptics QSB-522-BO is a QSFP28 fiber optic transceiver engineered for 100000 Mbit/s data transmission over multimode fiber. Designed in a silver housing and weighing 40 g, the module follows MSA form-factor standards and provides bidirectional 100GBASE-SR2-Bidi operation with LC Duplex connectivity. The transceiver supports digital diagnostics monitoring (DDM/DOM) for real-time reporting of supply voltage, laser current, optical transmit/receive power and temperature, and is compliant with CE, FCC and RoHS requirements. With an MTBF rating of 3,000,000 hours, the module is intended for use in common network hardware platforms such as switches, routers, storage systems and measurement equipment.

Advantages

The QSFP28 form factor enables 100 Gbit/s links in a compact, hot-pluggable package suitable for high-density racks. Bidirectional SR2-Bidi operation over LC Duplex reduces fiber count by transmitting and receiving on separate wavelengths over a single multimode fiber pair. Integrated digital diagnostics simplify monitoring and remote troubleshooting of optical links. The module's compliance with industry standards and use of tested components supports predictable compatibility and a long service life.

Key specifications

How to use

Install the QSFP28 transceiver into a compatible QSFP28 slot of your switch, router or other network device while the host is powered according to the manufacturer’s hot-plug guidelines. Connect LC Duplex multimode fiber patch cables matching the bidirectional SR2-Bidi specification. Ensure the host platform supports the 100GBASE-SR2-Bidi protocol and, if required, enable DDM/DOM support in the management interface to read real-time diagnostic data. Follow standard ESD precautions when handling the module and keep optical connectors clean to maintain link quality.

Recommendations

Use multimode fiber rated for the 100GBASE-SR2-Bidi distance class and LC Duplex connectors for best performance. Verify compatibility with the target hardware vendor and confirm DDM/DOM support if remote monitoring is needed. Regularly inspect and clean connectors and adhere to recommended insertion loss budgets for reliable links.
