Glasvezel-transceivermodule BlueOptics Q28-512-BO 100000 Mbit/s QSFP28

The BlueOptics Q28-512-BO is a QSFP28 fiber optic transceiver module designed for 100000 Mbit/s (100 Gbit/s) Ethernet links over multimode fiber. Finished in silver and weighing 40 g, the module implements a bidirectional SR2 Bidi transmission with LC duplex connections that comply with MSA form-factor and interface specifications. It supports simultaneous transmit and receive channels in the 832–918 nm wavelength range and includes Digital Diagnostics Monitoring (DDM) compatible with SFF-8472 for real-time reporting of parameters such as supply voltage, laser current, optical power and temperature.

Advantages

The module offers a standardized QSFP28 footprint and LC duplex connectivity for straightforward integration into compatible switches, routers and storage systems. Use of high-quality optical lasers and integrated circuits contributes to long service life and high mean time between failures, while DDM provides actionable remote diagnostics for maintenance and troubleshooting. Its bidirectional SR2 Bidi design enables high-density 100G links over a single multimode fiber pair, reducing cabling complexity.

Key specifications

How to use

Install the QSFP28 transceiver into an empty QSFP28 port of a compatible switch, router or other hardware following the host device manufacturer’s insertion and removal instructions. Connect LC duplex multimode fiber patch cables matched to the module’s bidirectional SR2 Bidi configuration. Verify link state and monitoring data via the host system and, if supported, use DDM to read voltage, laser currents, optical power and temperature values for diagnostics. Ensure the host device firmware and interface support QSFP28 modules and any vendor compatibility settings required for third-party transceivers.

Recommendations

For optimal performance, use multimode fiber and LC duplex patch cables specified for 100G SR2 Bidi links, maintain proper fiber cleanliness and bend radius, and confirm DDM support in the host hardware to enable remote diagnostics. Keep firmware of network devices up to date and follow manufacturer guidelines for hot-plugging transceivers.
