BlueOptics 100G-QSFP28-AOC25M-BO InfiniBand fibre optic cable 25 m Aqua

The BlueOptics 100G-QSFP28-AOC25M-BO InfiniBand fibre optic cable 25 m Aqua is a 25-meter active optical cable with QSFP28 connectors on both ends, designed for high-speed InfiniBand and Ethernet connections in data center and HPC environments. The aqua jacket identifies the cable type and helps with rack and cable management while the active optics enable reliable 100 Gbit/s-class links across the 25 m distance. The cable follows common industry electrical and mechanical interface practices for QSFP28 active optical cables and is intended for use where long-reach copper options are impractical.

Advantages

This 25 m BlueOptics QSFP28 AOC provides a single-cable solution for high-bandwidth links with low insertion loss and immunity to electromagnetic interference. The integrated optical transceivers reduce power consumption compared with multiple discrete transceivers and patching, and the standardized QSFP28 form factor ensures mechanical compatibility with QSFP28 ports. The longer 25 m length allows flexible placement of equipment across racks or between adjacent rooms without using additional patch panels.

Suitable for

• Data center uplinks and spine-to-leaf connections
• High-performance computing clusters and interconnects
• Switch-to-switch and switch-to-storage links supporting QSFP28 ports
• Environments requiring low-latency, high-throughput links over tens of meters

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 to QSFP28
• Length: 25 meters
• Typical data rates: suitable for 100 Gbit/s InfiniBand and Ethernet-class links
• Jacket color: aqua for easy identification
• Immunity: optical transmission immune to EMI/RFI

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into compatible QSFP28 ports on your network switches, routers or host adapters. Ensure ports are powered down or follow hot-plug guidelines of your equipment when inserting or removing the cable. Verify link negotiation and link speed through your device management interface and monitor signal status LEDs if available. Use standard cable management practices to route and secure the 25 m cable to avoid sharp bends and mechanical strain on connectors.

Usage recommendations

For reliable operation, avoid bending the cable below the manufacturer-recommended minimum bend radius and keep fiber connectors and port interfaces clean. Confirm that the connected devices support active optical QSFP28 modules and that firmware settings permit AOC links. In mixed-vendor setups, test interoperability and monitor link health after deployment.
