Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-2M-VA-BO 2m QSFP28 macho/macho

The BlueOptics Q28-AOC-2M-VA-BO InfiniBand fibre optic cable is a 2-metre active optical cable with QSFP28 male-to-male connectors designed for high-speed data transmission in demanding networking environments. It supports low-latency, high-bandwidth links between switches, servers and storage systems where InfiniBand connectivity and QSFP28 form-factor are required. The cable is intended for short-reach interconnects inside racks and between adjacent rack rows, offering predictable signal integrity and simplified cabling compared with discrete transceivers and patch fibres.

Advantages

The cable integrates optical transceivers and a lightweight, flexible fibre assembly to deliver high throughput with reduced power consumption relative to some copper alternatives. Its QSFP28 male connectors ensure a compact connection that is compatible with equipment accepting QSFP28 form-factor InfiniBand ports. The 2-metre length provides a balance between reach and cable management inside data center racks, while the active optical design minimizes electromagnetic interference and preserves signal quality over the specified distance.

Suitable for

• Interconnects between InfiniBand-enabled servers and switches inside a rack
• Connections between adjacent racks in high-performance computing clusters
• Low-latency links for storage arrays and compute nodes
• Data center environments requiring QSFP28 form-factor connections

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 2 metres
• Protocol compatibility: InfiniBand
• Designed for high-bandwidth, low-latency data links
• Suitable for short-reach, in-rack and adjacent-rack connections

How to use

Ensure both devices have compatible QSFP28 InfiniBand ports before connecting. Remove any protective caps from the QSFP28 connectors, align the keyed connector housings with the port receptacles and insert the plugs until they latch. Verify link status on connected equipment and configure the network or host interfaces according to your InfiniBand fabric settings. When disconnecting, release the QSFP28 latch mechanism and pull the connector straight out to avoid damage to the port or cable.

Recommendations

Route the cable along rack cable management trays and avoid tight bends; maintain the manufacturer’s minimum bend radius. Use dust caps when the cable is not connected and limit mechanical strain on the connector ends. For reliable operation, operate the cable within the data center environmental parameters of the connected equipment and follow standard electrostatic discharge (ESD) precautions during handling and installation.
