QSFP28 Transceiver Module BlueOptics QSFP28-100G-SR4-HU-BO Fiber Optic MTP/MPO

The BlueOptics QSFP28-100G-SR4-HU-BO is a 100GBASE-SR4 QSFP28 fiber optic transceiver module with an MTP/MPO connector designed for short-reach multimode fiber links. It supports 100 Gbit/s aggregated data transmission over multimode fiber with a maximum reach of about 100 m and implements QSFP28 form factor interoperability and MSA-compliant electrical and optical interfaces. The module is compact and lightweight (approximately 40 g) and is intended for installation in QSFP28 ports of switches, routers, storage systems and other networking equipment that support 100GBASE-SR4 optics.

Advantages

This transceiver provides a standardized QSFP28 interface and an MTP/MPO connector for high-density parallel fiber connections, enabling 100 Gbit/s links over multimode fiber. It supports digital diagnostics monitoring (DDM/DOM) for real-time readout of operating parameters such as supply voltage, laser bias current, optical output and input power, and temperature when supported by host hardware. The module is manufactured to MSA-compatible specifications and uses high-quality optical and electronic components to provide stable optical performance and extended operational lifetime.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port until it latches securely, taking care to follow the host equipment manufacturer’s handling and electrostatic discharge (ESD) precautions. Connect an MTP/MPO multimode fiber patch cord to the transceiver and ensure proper polarity and fiber type (OM3/OM4 recommended for 100 Gbit/s SR4 links). Verify link status and diagnostics via the host device management interface; enable or consult DDM/DOM readings if available. Remove the module by depressing the latch and sliding it out following the equipment vendor’s removal procedure.

Recommendations

For optimal performance, use certified OM3 or OM4 multimode fiber and high-quality MTP/MPO patch cords, ensure the host device firmware supports third-party QSFP28 modules and DDM/DOM monitoring, and follow ESD handling procedures. Regularly check diagnostic parameters to detect signal degradation early and maintain clean fiber endfaces and connectors to minimize insertion loss.
