BlueOptics CBL-525-BO InfiniBand/fibre optic cable 25 m QSFP28 Aqua

The BlueOptics CBL-525-BO InfiniBand/fibre optic cable 25 m QSFP28 Aqua is a 25-metre active optical cable (AOC) with QSFP28 male connectors on both ends. It is designed for high-speed links in data centers and high-performance computing environments, offering a multi-mode fibre connection that supports 100G-class short-range transmission protocols. The pre-assembled cable eliminates the need for patching or cleaning individual connectors and provides a direct QSFP28-to-QSFP28 optical link for latency-sensitive applications.

Advantages

This BlueOptics AOC follows MSA-compliant QSFP28 standards for plug-and-play compatibility with equipment that supports the equivalent 100GBASE-SR4 interfaces. The integrated transceivers on each end handle optical transmit and receive functions, enabling simultaneous bidirectional data transfer with reduced insertion loss compared to field-terminated assemblies. Because the cable uses multi-mode fibre and high-quality internal components, it is suitable for short-reach 100G applications while delivering stable performance and predictable link behavior.

Suitable for

• Interconnects between QSFP28 ports in data centre switches and routers
• High-performance computing clusters and InfiniBand fabrics
• Connections between storage systems and network fabrics requiring 100G short-range links
• Environments where optical immunity to electromagnetic interference is required

Key specifications

• Cable length: 25 metres
• Connector type: QSFP28 (male) on both ends
• Media: multi-mode fibre, active optical cable (AOC)
• Designed data rate: up to 100 Gbps over short range (100GBASE-SR4 class)
• Colour: Aqua

How to use

Install the BlueOptics CBL-525-BO by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the connector latches are fully engaged. Verify that both host devices support QSFP28 AOC modules and the 100GBASE-SR4 or compatible short-range optical protocol. If digital diagnostics (DDM/DOM) are required, confirm that the connected hardware supports SFF-8472 monitoring to view real-time parameters such as optical power and temperature. No additional fibre termination or patching is required for standard operation.

Usage recommendations

Route the cable to avoid sharp bends and maintain the minimum bend radius specified by the manufacturer for multi-mode fibre; avoid kinks and excessive tensile stress during installation. Use ESD precautions when handling QSFP28 connectors and ensure proper seating in host ports. For monitoring and troubleshooting, enable digital diagnostic monitoring on compatible devices to check optical power levels and temperatures. Replace the cable if visible damage to the jacket or connectors is observed.
