BlueOptics Q28-AOC-3M-IT-BO InfiniBand optický kabel 3m QSFP28 samec/samec

The BlueOptics Q28-AOC-3M-IT-BO InfiniBand fibre optic cable is a 3-metre active optical cable with QSFP28 male connectors on both ends. It is built to carry high-speed InfiniBand signals over short to medium reach links, providing low-latency, high-bandwidth connectivity suitable for data centres and high-performance computing racks. The cable's construction reduces electromagnetic interference and simplifies patching between compatible QSFP28 ports.

Advantages

This active optical cable supports native QSFP28 form-factor connections and is optimized for multi-lane high-speed data transfer. Its 3 m length balances flexibility and signal integrity for rack-to-rack or within-rack connections. The male-to-male QSFP28 terminations are designed for straightforward insertion into standard QSFP28 ports, and the optical medium ensures stable performance without the thermal and signal-loss issues associated with long copper traces.

Suitable for

• Interconnects between servers and switches in data centre racks
• High-performance computing clusters using InfiniBand
• Storage area networks requiring low-latency links
• Short to medium reach connections in network equipment rooms

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Optical type: Active optical cable (AOC)
• Interface: InfiniBand-compatible high-speed link
• Performance characteristics: low latency, multi-lane high-bandwidth transmission
• Application environment: data centres and HPC racks

How to use

Ensure both devices to be connected support QSFP28 ports and are powered down or in a state that permits hot-plugging according to the equipment manufacturer's guidelines. Align each QSFP28 male connector with the corresponding port and insert until the latch engages. Verify link status through the host device management interface or indicator LEDs. For removal, disengage the latch and pull the connector straight out to avoid damaging the port. Follow proper handling to avoid excessive bending of the cable near the connectors.

Recommendations

Place the cable to avoid tight bends and mechanical stress; maintain bend radii as specified by the equipment vendor. Use the 3 m length for rack-to-rack or within-rack connections where optical performance and low latency are required. Confirm firmware and driver compatibility on connected devices for InfiniBand operation.
