QSFP28-transceiver BlueOptics QSFP28-100G-SR4-BO 100m glasvezel

The BlueOptics QSFP28-100G-SR4-BO is a 100GBASE-SR4 fiber optic transceiver module with a QSFP28 interface designed for short-range multimode fiber links up to 100 meters. Housed in an aluminium casing and weighing approximately 40 g, the module supports MPO/MTP connectivity and transmits and receives at 850 nm to enable high-speed 100 Gbps links in data centers and networking equipment that accept QSFP28 SR4 optics.

Advantages

The module follows MSA-compliant QSFP28 form-factor and MPO/MTP connector standards to ensure interoperability with major vendor platforms that support 100GBASE-SR4 optics. Built with quality optical components and integrated circuitry, it provides reliable data transmission, digital diagnostics monitoring (DDM/DOM) for real-time status (such as supply voltage, laser bias current, transmit power, receive power and temperature), and an aluminium housing that contributes to mechanical robustness and heat dissipation. Its compact, lightweight design simplifies installation in dense switch and router environments.

Suitable for

• 100 Gbps uplinks and spine-leaf connections in data centers
• High-performance switching and routing platforms that accept QSFP28-SR4 modules
• Short-reach multimode fiber links up to 100 meters using MPO/MTP cabling
• Fibre Channel over Ethernet and other high-speed optical network applications

• Digital diagnostics monitoring (DDM/DOM) supported

How to use

Install the QSFP28-100G-SR4-BO into a compatible QSFP28 port on a switch, router or storage device while the host is powered down or following the vendor's hot-swap procedure. Connect the MPO/MTP multimode fiber patch cord between the module and the corresponding MPO/MTP port or patch-panel. Verify link status via the host device and, if available, read diagnostics information through the hardware management interface to confirm optical power, temperature and supply values. Ensure the hosting platform explicitly supports SR4 QSFP28 optics or has been validated for third-party transceivers.

Recommendations

Use OM3/OM4 multimode fiber for optimal reach and performance within the specified 100 m range, and follow vendor guidelines for MPO/MTP polarity and patching. Confirm DDM/DOM support on the host device before relying on remote diagnostics. For best results, test a sample module in your target hardware to validate full interoperability and link performance.
