CBO SFP-DAC40-1m 1 m QSFP-direct aansluitkabel (DAC) voor hogesnelheidsverbindingen

The CBO SFP-DAC40-1m is a 1 metre QSFP direct attach copper (DAC) cable from BlueOptics, engineered for short-reach, high-speed links in data centre and server-rack environments. This pre-terminated copper assembly combines QSFP connectors on both ends with a fixed-length copper conductor to provide a low-latency, cost-efficient alternative to optical transceivers and fibre patching when connecting compatible switches, routers and servers.

Advantages

This QSFP DAC cable delivers predictable signal integrity and low power consumption for short interconnect runs. Its fixed 1 m length simplifies cable management in dense racks, reduces insertion components compared with separate transceivers and fibre, and eliminates the need for additional SFP/SFP+ optical modules. The direct attach approach reduces total solution cost while maintaining the high throughput required for aggregation, top-of-rack and server-to-switch connections.

Suitable for

• Short-reach connections between QSFP-capable switches and routers
• Server-to-switch links in top-of-rack deployments
• Aggregation points and spine-leaf fabric interconnects within a rack
• Environments where low latency and low power are important

Key specifications

• Cable type: Direct attach copper (DAC) with QSFP connectors
• Length: 1 metre
• Connector type: QSFP plug on both ends for high-density QSFP ports
• Intended reach: Short-distance, in-rack or adjacent-rack connections
• Performance: Designed for high-speed links with low-latency characteristics
• Physical: Pre-terminated, single fixed-length assembly for simplified installation

How to use

Install the QSFP DAC by inserting each QSFP connector into the corresponding QSFP port on the network devices until the retention latch engages. Ensure both devices support QSFP direct attach copper connections and are configured for the intended link speed. Route the 1 m cable to avoid sharp bends and mechanical strain, and confirm link status through the devices' interface indicators or management tools. For replacement, power down or follow hot-swap guidance from the device manufacturer if supported, then remove the cable by releasing the latch and pulling the connector straight out.

Recommendations

Use this 1 m QSFP DAC cable for in-rack or short adjacent-rack interconnects where a fixed short length is sufficient; avoid running it through cable trays over long distances. Verify compatibility with the specific QSFP ports on your switches, routers and servers before deployment and follow equipment vendor guidance for hot-swap and link configuration.
