BlueOptics QSFP-100G-AOC-50M-HU-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male

The BlueOptics QSFP-100G-AOC-50M-HU-BO InfiniBand fibre optic cable is a 50 meter active optical cable (AOC) with QSFP28 male-to-male connectors designed for 100G high-speed links. Built to MSA-compliant QSFP28 specifications, this multi-mode AOC integrates optical transmitter and receiver modules in the cable ends and supports 100GBASE-SR4 signalling for short-reach high-bandwidth interconnects. The cable is intended for rack-to-rack and intra-rack connections in data centers and high-performance computing environments where deterministic 100Gb/s throughput and low latency are required.

Advantages

This BlueOptics QSFP28 AOC offers plug-and-play deployment with no external transceivers required, reducing heat and power consumption compared with separate SFP/optical transceiver plus fibre assemblies. The integrated transmitter/receiver design provides stable 100G links on multimode fibre over the specified 50 m reach and ensures compatibility with equipment that supports QSFP28 100GBASE-SR4 and InfiniBand configurations. The male-to-male QSFP28 form factor simplifies direct module-to-module connections between supported switches, routers and storage systems.

Suitable for

• Data centre rack-to-rack 100G interconnects
• High-performance computing clusters and InfiniBand fabrics
• Switch-to-switch and switch-to-storage 100G links within 50 meters
• Environments requiring low-latency, high-throughput short-reach connections

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC) with integrated Tx/Rx modules
• Supported link standard: 100GBASE-SR4 / InfiniBand 100G-compatible
• Maximum reach: 50 meters over multimode fibre
• Data rate: Up to 100 Gbit/s
• Optical medium: Multimode fibre
• Power characteristics: Lower system power than separate transceiver + fibre assembly due to integrated design

How to use

Insert each QSFP28 male connector into the corresponding QSFP28 port on both network devices until the latch engages. Ensure devices are powered and configured to enable 100GBASE-SR4 or compatible InfiniBand link settings. No external SFP or separate transceiver modules are required; the cable contains the active optical transceivers. Verify link status and correct port configuration in the device management interface and perform any required firmware or driver checks to ensure compatibility.

Recommendations

For reliable operation, use the BlueOptics QSFP-100G-AOC-50M-HU-BO in supported QSFP28 ports and within the specified 50 m reach on multimode fibre channels. Avoid tight bends and mechanical stress on the cable; maintain recommended bend radii for multimode AOC assemblies and route the cable away from sharp edges and heat sources. Confirm that host hardware firmware and OS drivers support QSFP28 AOC modules to prevent link negotiation issues.
