BlueOptics Q28-AOC-2M-RW-BO InfiniBand fibre optic cable QSFP28 2m Male/Male

The BlueOptics Q28-AOC-2M-RW-BO InfiniBand fibre optic cable QSFP28 2m Male/Male is a 2‑metre active optical cable designed for high-speed connectivity in data centres and high-performance computing environments. With QSFP28 interfaces at both ends in a male/male configuration, the cable supports low-latency, high-bandwidth links between switches, servers and adapters that accept QSFP28 transceivers. The compact, lightweight construction reduces rack clutter while maintaining signal integrity over the two-metre reach.

Advantages

This InfiniBand QSFP28 cable provides high data throughput and reduced electromagnetic interference compared with copper alternatives, enabling stable links for demanding applications. The 2 m length balances flexibility and signal performance for short to mid-range connections inside racks or between adjacent racks. Plug-and-play QSFP28 connectors simplify installation and reduce configuration time.

Suitable for

• Interconnecting QSFP28 ports on switches and routers within the same rack
• Server-to-switch uplinks in high-performance computing clusters
• Storage network connections requiring low latency and high bandwidth
• Data centre top-of-rack and middle-of-row cabling where 2 m reach is sufficient

Key specifications

• Connector configuration: QSFP28 male to QSFP28 male
• Length: 2 metres
• Form factor: Quad Small Form-factor Pluggable 28 (QSFP28)
• Use environment: Data centre and server room applications
• Typical benefits: High bandwidth, low latency, immunity to electromagnetic interference

How to use

Ensure both devices have QSFP28 ports and are powered down or set to accept hot‑plugging as per your hardware guidelines. Align the QSFP28 connectors with the port guides and insert until the connector latches. Verify link status through device LEDs or management interfaces and confirm negotiated speed and link health. To remove, release the connector latch and withdraw the cable straight out to avoid damaging the port. Follow your equipment vendor’s instructions for hot-swap procedures if applicable.

Recommendations

Install the cable with gentle bends and avoid tight radii near the connectors to preserve optical performance. Keep the cable away from high-heat sources and avoid placing heavy objects on it. For reliable operation, use the 2 m length for intra-rack or adjacent-rack connections and verify compatibility with the connected QSFP28 devices and firmware.
