BlueOptics ET7402-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics ET7402-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3‑metre active optical cable (AOC) with QSFP28 connectors on both ends. Engineered for high‑speed, short‑reach interconnects, this multi‑mode fibre cable integrates transmitters and receivers in each QSFP28 module and follows MSA pinout and mechanical form factors for compatibility with QSFP28 ports that support 100GBASE‑SR4 and InfiniBand protocols. Its male‑to‑male QSFP28 configuration enables direct, low‑latency links between switches, routers, servers and storage systems within racks or across adjacent racks.

Advantages

The integrated optical transceivers and multi‑mode fibre provide stable 100 Gbps connectivity over a 3 m span while reducing electromagnetic interference and heat compared with equivalent copper assemblies. Compliance with common QSFP28 form‑factor standards ensures broad interoperability with networking devices that accept compatible active optical cables. The compact, cable‑integrated design simplifies cabling management in dense equipment environments and supports high throughput applications with minimal protocol overhead.

Key specifications

How to use

Inspect both QSFP28 connectors for dust and contamination before installation and ensure compatible QSFP28 ports on your devices. Insert each QSFP28 plug firmly into the corresponding port until the latch engages. Devices should detect the link automatically if they support the cable type and protocol; verify link status in your device management interface. For removal, depress the latch mechanism and pull the module straight out to avoid damaging the port or cable.

Recommendations

Use the cable within a controlled rack environment, avoiding tight bends and extreme tension. Keep dust caps on unused QSFP28 ports and store the cable coiled loosely when not in use. Verify device compatibility with QSFP28 AOC modules and firmware support for 100GBASE‑SR4 or InfiniBand to ensure reliable operation.
