Direct Attach -kaapeli (DAC) CBO BlueOptics QSFP 40 Gbit/s 1 m, QSFP uros - QSFP uros, musta

CBO BlueOptics DAC-QSFP-40G-1M is a 1 m Direct Attach Cable (DAC) with QSFP male-to-male connectors that supports 40 Gbit/s. It is designed for short-range interconnects in data centres and network equipment, providing a fixed copper link with low latency and predictable performance. The cable is suitable for connecting QSFP ports on switches, routers and servers where a compact, cost-effective 40 Gbit/s connection is required.

Advantages

The Direct Attach Cable delivers a ready-to-use electrical connection without the need for transceivers, reducing power consumption and equipment footprint. Its short, fixed-length design minimises signal loss and latency while offering consistent throughput at 40 Gbit/s. The integrated QSFP male connectors ensure secure mating and straightforward installation. The cable’s construction provides mechanical stability for dense rack environments and reduced heat generation compared to optical alternatives.

Suitable for

• Top-of-rack switch to switch links in data centres
• Server to switch high-bandwidth connections within racks
• Short-reach interconnects in network aggregation and spine-leaf architectures

Key specifications

• Connector type: QSFP male to QSFP male
• Data rate: 40 Gbit/s
• Length: 1 metre
• Cable type: Direct Attach Copper (DAC)
• Typical use: short-range, boardroom or rack-level interconnects

How to use

Power down or follow hot-plug procedures of your network equipment as recommended by the vendor. Align each QSFP male connector with the corresponding QSFP port and insert until the latch engages. Verify link status using the device’s management interface or indicator LEDs. For removal, depress the connector latch and pull straight out to avoid damaging ports. Use the cable within its rated bend radius and avoid tension that could stress the connectors.

Recommendations

Choose this DAC for reliable, low-latency 40 Gbit/s connections within racks or short data-centre runs. Ensure compatibility with your switch or server QSFP ports and follow vendor guidance for hot-plugging and environmental limits.
