DAC Cable CBO QSFP 470-AAFE-BL, direct-attach copper, 1 m, BlueLAN

The BlueOptics DAC Cable CBO QSFP 470-AAFE-BL is a passive direct-attach copper (DAC) assembly with QSFP connectors and a 1 m cable length. It is engineered for short-range, high-speed connections between QSFP ports in switches, servers and storage systems, providing a low-latency physical link without the need for separate optical transceivers. The compact, single-meter cable is intended for rack-to-rack or intra-rack installations where a reliable, cost-effective copper connection is required.

Advantages

This passive DAC cable offers straightforward connectivity with minimal power consumption and reduced component count compared to transceiver-based links. The QSFP interface supports high data-rate transmissions while the fixed 1 m length minimizes insertion loss and signal degradation across short distances. The cable's construction is optimized for consistent electrical performance and compatibility with standard QSFP ports in networking equipment.

Suitable for

• Short-range links between QSFP-equipped switches and routers
• Direct connections between servers and storage appliances within a rack
• High-density rack environments requiring compact, low-latency cabling
• Cost-sensitive deployments where passive copper is preferred over optical transceivers

Key specifications

• Connector type: QSFP to QSFP (quad small form-factor pluggable)
• Cable type: Passive direct-attach copper (DAC)
• Length: 1 meter
• Typical applications: Short-reach data center interconnects, server-to-switch links
• Color: Blue

How to use

Insert each QSFP connector into the corresponding QSFP port on your network devices until the connector latches. Ensure devices are powered down or that hot-plugging is supported and recommended by the equipment vendor before insertion or removal. Verify link status indicators on the connected equipment to confirm a successful connection. For optimal performance, avoid bending the cable sharply and maintain proper cable management to prevent strain on the connectors.

Recommendations

Use this 1 m passive DAC for short, fixed-length connections inside racks or between adjacent racks. Confirm QSFP port compatibility and supported data rates on both ends prior to deployment. Do not exceed recommended bend radius and protect the cable from mechanical stress to preserve signal integrity and connector lifespan.
