QSFP Transceiver Module BlueOptics QSFP-100G-SR4-AL-BO Fiber Optic MPO

The BlueOptics QSFP-100G-SR4-AL-BO is a QSFP28 fiber optic transceiver module designed for 100G data transmission over multimode fiber. It features an MPO/MTP connector and an aluminium housing, providing a compact and lightweight solution (approx. 40 g) for short-range high-speed links in data centers and enterprise networks. The module implements 100GBASE-SR4 optics with 850 nm wavelength for transmit and receive channels and is compatible with systems that accept QSFP28 SR4 modules.

Advantages

The module delivers 100 Gbit/s aggregate bandwidth using four parallel 25 Gbit/s lanes and supports optical transmission over multimode fiber with an MPO connector for simplified high-density cabling. Its aluminium enclosure offers mechanical robustness while keeping weight low. The design follows common MSA QSFP28 form-factor conventions to ensure interoperability with equipment that accepts standard SR4 QSFP28 transceivers. Built-in digital diagnostic monitoring (DDM/DOM) enables real-time reporting of electrical and optical parameters where supported by the host hardware.

Suitable for

• Short-reach 100G Ethernet connections in data centers (switch-to-switch or switch-to-fabric)
• High-performance networking aggregation and spine-leaf architectures
• Storage and server interconnects requiring multimode fiber links

How to use

Install the QSFP-100G-SR4-AL-BO into a compatible QSFP28 slot following your host device manufacturer’s insertion and removal procedures. Use an MPO/MTP multimode fiber patch cord or cassette to connect the transceiver to the remote endpoint or patch panel. Ensure the host device supports 100GBASE-SR4 QSFP28 modules and, if required, enable or verify DDM/DOM support for real-time monitoring. Observe standard ESD precautions and secure proper cable polarity and fiber type (multimode) for expected link performance.

Recommendations

Use OM3/OM4 multimode fiber for best short-range 100G performance and follow the equipment vendor’s guidance for maximum link distance. Verify compatibility with the switch or router firmware and, if possible, test the transceiver in your environment before deployment to confirm interoperability and expected link characteristics.
