Offers low latency, simplified cabling and compatibility with devices using QSFP+ ports for 40GbE/InfiniBand links.

## Long description

Passive InfiniBand direct-attach copper cable by BlueOptics, model EX-QSFP-40GE-DAC-5M-BL, is a 5 metre QSFP+ to QSFP+ cable designed for short-range, high-throughput interconnects. It provides a direct electrical connection for 40GbE and InfiniBand links between switches, servers and storage systems within a rack or between adjacent racks. The cable is intended to deliver low latency and reliable signal integrity for data centre topologies where optical transceivers are not required.
Advantages
This passive QSFP+ to QSFP+ cable offers a low-latency, cost-effective cabling option for short-distance high-speed links. As a copper direct-attach solution it simplifies rack cabling, eliminates the need for separate transceivers and reduces power consumption compared with active or optical alternatives. The 5 m length provides flexibility for connections between devices in the same rack or neighbouring racks while maintaining consistent 40GbE/InfiniBand performance.
Suitable for
 40GbE or InfiniBand links between top-of-rack switches
 Server-to-switch connections in high-density rack deployments
 Storage clustering and direct-attached high-throughput links
 Short-reach interconnects where low latency is required
Key specifications
 Connector type: QSFP+ to QSFP+
 Length: 5 metres
 Transmission: passive copper direct-attach
 Supported link speeds: 40GbE and InfiniBand rates compatible with QSFP+ ports
 Typical use: short-range, high-throughput interconnects within racks or adjacent racks
 Latency: low, suitable for latency-sensitive applications
How to use
Inspect both QSFP+ ports for dust and damage before installation. Align and insert each QSFP+ connector into the corresponding port until the latch engages. Ensure connected devices are configured for the appropriate 40GbE or InfiniBand link settings and verify link status through device management interfaces. For removal, release the connector latch and withdraw the cable evenly to avoid stressing the ports. Avoid sharp bends and excessive torsion in the cable during and after installation.
Usage recommendations
Use this passive DAC for intra-rack or adjacent-rack connections up to 5 metres where optical transceivers are not required. Maintain bend radius and strain relief practices recommended for QSFP+ copper cables, and verify compatibility with the switch or server vendor for full link feature support.
