Fiber optic transceiver module BlueOptics 845970-B21-BO QSFP28 100G

The BlueOptics 845970-B21-BO QSFP28 100G fiber optic transceiver module is designed for 100 Gigabit Ethernet environments that require a compact, MSA-compliant QSFP28 interface. Constructed with an aluminium body and weighing approximately 0.11 kg, this module supports high-speed optical links and conversion between 100GBASE and 25GBASE signals when used as a QSFP28-to-SFP28 converter. The module is intended for integration into network switches, routers, storage systems and other hardware platforms that support QSFP28 optics and offers simultaneous transmit and receive optical channels for multimode and single-mode fibers.

Advantages

The module follows MSA QSFP28 mechanical and electrical specifications, enabling broad compatibility with equipment that accepts standard QSFP28 transceivers. Its aluminium housing provides a durable, thermally conductive enclosure while keeping weight low. The transceiver supports digital diagnostics monitoring (DDM/DOM) to report key operational parameters such as supply voltage, laser bias current, optical output and input power levels, and temperature for remote error analysis and maintenance. Designed for high data-rate applications, it is suitable for Ethernet and Fibre Channel over Ethernet links up to 100 Gbit/s when supported by the host hardware.

Suitable for

• 100 Gigabit Ethernet uplinks and backbone connections
• QSFP28-to-SFP28 conversion scenarios where supported
• Data center switches, routers and storage system interconnects
• High-speed links over multimode and single-mode fiber

Key specifications

• Form factor: QSFP28 multi-rate optical transceiver
• Rated data rate: up to 100 Gbit/s (dependent on host support)
• Housing: aluminium enclosure
• Weight: approx. 0.11 kg
• Optical support: multimode and single-mode fiber (protocol and reach depend on fiber type and module variant)
• Diagnostics: Digital Diagnostics Monitoring (DDM/DOM) compliant with MSA SFF-8472

How to use

Install the BlueOptics QSFP28 module into a compatible QSFP28 slot on the host device while the device is powered off or per the host vendor’s hot-plug guidelines. If using the module as a QSFP28-to-SFP28 converter, ensure the host platform supports converter operation and the corresponding firmware. Connect appropriate single-mode or multimode fiber patch cords to the transceiver’s optical interface and secure connections at patch panels or directly to peer transceivers. Verify link status through the host device management interface and, if available, read DDM/DOM parameters to confirm optical power levels and operating temperature.

Recommendations

To achieve optimal performance, use quality fiber patch cords and maintain clean connector endfaces. Confirm host hardware compatibility and firmware support for QSFP28 and QSFP28-to-SFP28 conversion functions before deployment. Monitor DDM/DOM readings regularly to detect degradations in optical power or temperature shifts and follow standard ESD precautions when handling the transceiver.
