Direct-attach copper cable BlueOptics CAB-Q-Q-1M is a 1 m QSFP Male–Male assembly engineered to carry 40 Gbit/s between compatible QSFP ports. The CAB-Q-Q-1M provides a short-reach, low-latency physical link for interconnects in high-density rack environments, connecting switches, servers and network appliances with a single, fixed-length copper cable. The design simplifies cabling in data centers and equipment racks while offering a cost-effective alternative to active optical modules for short distances.

Advantages

The 1 m QSFP to QSFP direct-attach copper cable offers predictable performance for 40 Gbit/s links with minimal signal conversion and low power consumption. The passive copper assembly eliminates the need for separate transceivers, reducing port and module costs and simplifying inventory management. Its compact form factor supports high-density deployments and provides stable latency characteristics suitable for short interconnects inside racks or between adjacent enclosures.

Key specifications

How to use

Insert each QSFP connector into the device QSFP ports until the latch engages; verify link status on connected devices according to their interface indicators and management software. Ensure both endpoints support passive QSFP direct-attach copper connections at 40 Gbit/s and that port configurations (speed, duplex, and any required lane mapping) match on both devices. Route the cable to avoid sharp bends, excessive strain, and sources of electromagnetic interference; maintain recommended bend radius and secure the cable within the rack to prevent movement.

Recommendations

Use the cable for short, intra-rack or adjacent-rack connections where 40 Gbit/s performance and low latency are needed. For longer distances or environments sensitive to electrical interference, consider fiber-optic solutions or active cables. Inspect connectors before installation and avoid excessive force when inserting or removing the QSFP plugs.
