Nvidia MCP1600-C02AE26N InfiniBand fibre optic cable 2.5 m QSFP28 Black

The Nvidia MCP1600-C02AE26N InfiniBand fibre optic cable is a 2.5 metre, QSFP28-ended assembly designed for high-speed, low-latency links in data centres and advanced networking environments. Engineered by MELLANOX, this black fibre optic cable provides a clean connection between QSFP28-capable ports, offering consistent throughput suitable for modern HPC, storage and switch-to-switch topologies.

Advantages

This 2.5 m InfiniBand fibre optic cable delivers reliable signal integrity and low insertion loss across short to mid-range rack connections. The QSFP28 connectors on both ends simplify installation in compatible cages and modules, while the black jacket gives a professional, low-visibility appearance in structured cabling runs. The cable is intended to maintain stable data transfer rates and minimal latency under typical data centre operating conditions.

Suitable for

• High-performance computing clusters requiring low-latency interconnects
• Switch-to-switch or switch-to-server connections in data centres
• Storage area networks and backup systems with QSFP28 ports
• Short- to mid-range rack-to-rack links within server rooms

When it may not be suitable

This fibre optic cable is intended specifically for QSFP28 InfiniBand interfaces; it is not suitable for systems that require different connector types (for example SFP+, RJ45 or proprietary optical interfaces) without appropriate adapters. It is designed for short to mid-range interconnects rather than very long-distance fibre runs between separate buildings or campus sites.

Key specifications

• Cable length: 2.5 m
• Connector type: QSFP28 on both ends
• Cable type: InfiniBand fibre optic
• Colour: Black
• Intended use: Data centre and networking interconnects

How to use

Install the cable by aligning each QSFP28 connector with the corresponding port until the latch engages; avoid forcing the connector. Route the cable along structured pathways to prevent sharp bends and mechanical strain. Ensure both endpoints are powered down or that hot-plug procedures recommended by the equipment manufacturer are followed if connecting live. After installation, verify link status and performance through the host or switch management interfaces.

What to consider before purchase

• Confirm that both endpoints support QSFP28 InfiniBand interfaces
• Check required cable length and allow slack for rack routing
• Verify compatibility with your switch, server or HBA vendor recommendations
• Assess environmental requirements such as bend radius and cable management needs

Usage recommendations

For optimal performance, use this QSFP28 InfiniBand cable within the recommended bend radius, maintain secure but strain-free terminations, and pair it with devices that explicitly support QSFP28 InfiniBand links. Regularly inspect connectors for contamination and follow standard data centre cleaning procedures to preserve link quality.
