QSFP transceiver BlueOptics QSFP-100GBASE-SR4 100000 Mbit/s 850 nm

The BlueOptics QSFP-100GBASE-SR4 is a fiber optic transceiver module engineered for short-reach, high-speed connectivity in data centers and high-performance computing environments. It supports a maximum data rate of 100000 Mbit/s and operates at an 850 nm wavelength over multimode fiber, offering reliable 100 Gigabit Ethernet links up to approximately 100 metres. The module uses a QSFP28-compatible form factor designed for compact, high-density switch and server ports.

Advantages

This QSFP transceiver provides consistent 100G performance with low power consumption and a standardized QSFP28 interface for easy integration into existing networking equipment. Its multimode 850 nm optics are optimized for cost-effective short-range connections, while the compact QSFP form factor enables high port density in racks and chassis. The module is suitable for hot-plug use and typical data center operating conditions.

Suitable for

• 100 Gigabit Ethernet links within data center racks and between adjacent racks
• High-performance computing clusters requiring low-latency, high-bandwidth interconnects
• Network equipment upgrades where QSFP28 ports are available
• Short-reach multimode fiber links (up to ~100 m) using OM3/OM4 cabling

Key specifications

• Interface type: QSFP28 form factor
• Maximum data transfer rate: 100000 Mbit/s (100 Gbps)
• Operating wavelength: 850 nm
• Link type: Multimode fiber (MMF)
• Typical reach: up to 100 metres over multimode fiber

How to use

Insert the QSFP-100GBASE-SR4 transceiver into an available QSFP28 slot on a compatible switch, router or server port following the host device manufacturer's instructions for hot-plug modules. Connect appropriate multimode fiber patch cords (matching duplex/lane breakout or MPO/MTP configuration as required) and ensure fiber connectors and ports are clean before mating. Verify link status and speed via the network device management interface and monitor for optical signal levels within specified ranges.

Recommendations

Use OM3 or OM4 multimode fiber to achieve the stated range and maintain proper channel performance. Keep connectors clean and use dust caps when the transceiver is not in use. Match the transceiver to equipment supporting QSFP28 ports and 100GBASE-SR4 standards for full compatibility. For longer distances or single-mode requirements, select an appropriate transceiver type designed for those conditions.
