InfiniBand/fibre optic cable Cisco QSFP-H40G-AOC3M= 3 m

The Cisco QSFP-H40G-AOC3M= is a 3-meter active optical cable with QSFP+ connectors on both ends, designed for high-speed InfiniBand and fibre optic links. It provides a compact, pre-terminated connection for short-reach interconnects in data centers and enterprise networks, supporting high-bandwidth, low-latency transmission between switches, routers and servers.

Advantages

This active optical cable combines QSFP+ connectivity with a fixed 3 m length to deliver consistent performance and simplified deployment without field termination. The pre-terminated design reduces installation time and potential connector degradation, while the active optical components enable low power consumption and reliable signal integrity over the specified reach. The cable is compatible with QSFP+ ports and intended for high-throughput environments.

Suitable for

• Short-reach interconnects inside data centers
• Connections between switches, routers and servers
• High-bandwidth InfiniBand links
• Low-latency storage and compute fabrics

How to use

Install the Cisco QSFP-H40G-AOC3M= by inserting each QSFP+ connector into compatible QSFP+ ports on the devices to be linked. Ensure port compatibility and proper insertion until the connector latches. Use vendor documentation to verify switch or NIC settings if any port configuration is required. Avoid bending the cable beyond manufacturer-recommended bend radius and route it to prevent mechanical stress on the connectors.

Recommendations

Use this 3 m active optical cable for short-distance, high-bandwidth connections in racks and between adjacent racks. Confirm QSFP+ port compatibility with Cisco or third-party equipment and follow electrostatic discharge (ESD) precautions when handling the connectors.
