CBO InfiniBand-directaansluitkabel EX-QSFP-40GE-DAC-3M 3 m passief QSFP+

CBO InfiniBand Direct Attach Cable EX-QSFP-40GE-DAC-3M is a 3-metre passive QSFP+ to QSFP+ copper cable designed for short-reach, high-throughput connections. It provides a physical link for 40GbE and InfiniBand environments between switches, servers and storage devices, offering low latency and consistent signal integrity for rack-to-rack or within-rack deployments.

Advantages

The passive QSFP+ direct attach design eliminates the need for separate transceivers, reducing power consumption and simplifying installation. With a 3 m length and robust copper construction, the cable supports high data rates with minimal latency and predictable performance. Compatibility with standard QSFP+ ports makes it suitable for many data centre and enterprise network setups while keeping total cost of ownership lower than active optical solutions for short distances.

Key specifications

How to use

Insert each QSFP+ plug into compatible QSFP+ ports on the devices to be connected, ensuring the connectors are aligned and fully seated. Once connected, verify link status through the device management interfaces and configure the network ports for 40GbE or InfiniBand as required. For best results, route the cable to avoid sharp bends and minimize mechanical stress on the connectors.

Recommendations

Use this passive DAC for short-distance connections up to 3 metres inside racks or between adjacent racks. Avoid using the cable in environments with excessive vibration, high temperatures, or where electromagnetic interference could be an issue. Inspect connectors before installation and handle by the plug housings to prevent damage to the contacts.
