BlueOptics InfiniBand fibre optic cable 5 m QSFP28 Aqua

The BlueOptics InfiniBand fibre optic cable 5 m QSFP28 Aqua is a 5-metre active optical cable (AOC) with QSFP28 connectors on both ends, designed for high-speed 100G data links over multimode fibre. Compatible with platforms that support QSFP28 100GBASE-SR4 AOCs, this aqua-coloured cable integrates transmitter and receiver modules in each connector to enable simultaneous optical send and receive operations. The pre-assembled design reduces the need for patch cords and delivers stable, low-latency connectivity for data centers, switches, routers and storage systems.

Advantages

This BlueOptics 5 m QSFP28 AOC supports 100G data rates using multimode fiber and conforms to QSFP28 MSA electrical and mechanical specifications for interoperability. The cable provides immunity to electromagnetic interference, stable bandwidth over its length and integrated digital diagnostics monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, transmitter output power, received power and temperature when supported by host hardware. Components follow industry quality standards to provide extended service life and high availability for critical network links.

Suitable for

• 100G interconnects between QSFP28-capable switches and routers
• High-speed connections for storage systems and SAN fabrics
• Top-of-rack and spine aggregation in data centre deployments
• Low-latency links for HPC and InfiniBand environments that accept QSFP28 AOCs

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 ports on your network devices until they click into place. Ensure both devices support 100GBASE-SR4 or QSFP28 AOC modules and that any required firmware or software compatibility settings are enabled. If your host equipment supports DDM/DOM, you can monitor optical parameters through the device management interface. Avoid tight bends and physical stress on the cable; maintain minimum bend radius as specified by the equipment vendor.

Recommendations

Prior to deployment, verify hardware compatibility and DDM/DOM support in your switches or servers. Route the cable to avoid sharp bends and mechanical strain, keep connectors covered until installation to prevent contamination, and use the AOC for short-reach 100G links within racks or between adjacent racks for optimal signal integrity.
