Product information

Description

CBO DAC Cable AT-QSFP05CU 5 m Passive Copper QSFP+ direct attach cable is a 5-metre passive copper interconnect engineered for short-reach 40GbE links. Compatible with QSFP+ ports, this direct attach cable delivers low-latency electrical connectivity between switches, servers and storage within racks and adjacent rack rows. The passive copper design provides energy-efficient signal transmission for high-throughput applications where fibre transceivers are unnecessary and cost-effective, reliable cabling is required.

Advantages

The passive copper QSFP+ direct attach cable offers low latency and stable electrical performance for 40GbE connections while eliminating the need for separate transceivers. Its fixed 5 m length simplifies cable management in data centres and rack environments and reduces power consumption compared with active optical alternatives. The robust connector interfaces support high-density port installations and enable straightforward plug-and-play deployment without additional configuration.

Suitable for

  • Short-reach 40 Gigabit Ethernet links inside racks
  • Direct server-to-switch and switch-to-switch connections
  • High-density data centre interconnects and top-of-rack installations
  • Storage area network (SAN) links over short distances

Key specifications

  • Interface: QSFP+ to QSFP+ direct attach copper
  • Length: 5 metres
  • Data rate: suitable for 40GbE applications
  • Cable type: passive copper twinax
  • Typical use: short-reach, rack-to-rack or within-rack connections

How to use

Install the cable by inserting each QSFP+ connector into the corresponding port on your network equipment until the latch engages. Ensure both devices support passive QSFP+ direct attach copper connections and that ports are rated for 40GbE operation. Route the cable to avoid sharp bends and mechanical stress; maintain recommended bend radius for twinax cables. No additional configuration or external power is required for the cable itself, but verify link settings on connected devices if auto-negotiation does not establish a link automatically.

Usage recommendations

For reliable performance, use this 5 m passive QSFP+ cable for short, fixed-length connections inside racks or between adjacent racks. Avoid installation near strong electromagnetic interference sources and do not exceed the specified bend radius. Check compatibility lists of connected hardware to confirm QSFP+ passive DAC support before deployment.
