BlueOptics Q28-AOC-1M-BC-BO InfiniBand/fibre optic cable QSFP28 1m Male/Male

The BlueOptics Q28-AOC-1M-BC-BO InfiniBand/fibre optic cable QSFP28 1m Male/Male is a 1-metre active optical cable engineered for high-speed data transmission between QSFP28 ports. It provides a direct optical connection in a compact, single-cable form factor suitable for short-reach interconnects inside racks and between adjacent network equipment. The male-to-male QSFP28 terminations support standard QSFP28 interfaces used in modern switches, adapters and servers, enabling multi-lane 100Gb/s class links depending on connected hardware.

Advantages

This QSFP28 active optical cable offers high bandwidth with low latency and predictable signal integrity for short-reach links. Its optical medium reduces electromagnetic interference compared to copper solutions and can help lower heat generation in dense rack environments. The fixed 1 m length provides a tidy, low-loss connection where longer cables are unnecessary, simplifying cable management and reducing insertion loss variability.

Suitable for

• Connectors between QSFP28 ports on switches, routers and network adapters
• Top-of-rack and adjacent-rack interconnects in data centres
• High-performance computing and InfiniBand fabric links requiring low-latency, high-bandwidth connections
• Short-reach optical links inside server cabinets and equipment racks

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active Optical Cable (AOC)
• Length: 1 metre
• Supported interface class: QSFP28 (multi-lane 100Gb/s class links depending on hardware)
• Medium: optical fibre (active transceivers integrated)
• Typical applications: short-reach data centre interconnects and InfiniBand links

How to use

Verify that both devices support QSFP28 interfaces and are configured for the intended link speed and protocol. Align the QSFP28 plugs with the ports and insert gently until the retention mechanism engages. Ensure that the cable routing avoids tight bends and direct mechanical stress on the connectors. Monitor the link status on connected devices and confirm proper negotiation and link speed after insertion. Remove the cable by depressing the QSFP28 latch or pull-tab and extracting the plug straight out to avoid damaging the port.

Recommendations

Use the cable for short, high-bandwidth connections within racks or between adjacent racks. Maintain minimum bend radius specified by the manufacturer, avoid excessive pulling force on the connectors, and keep connector endfaces clean. Confirm compatibility with your networking equipment and firmware to ensure full support of QSFP28 link speeds and features.
