DAC kábel CBO QFX-QSFP-DAC-0.5M-BL 0,5 m QSFP na QSFP priame pripojenie

The BlueOptics DAC cable QFX-QSFP-DAC-0.5M-BL is a 0.5 m passive QSFP-to-QSFP direct attach copper cable designed for short-reach interconnects in high-performance network environments. It provides a compact, low-latency physical connection between QSFP ports on switches, routers and servers, intended for reliable rack-to-rack or intra-rack links where a fixed copper assembly is preferred over active optical modules.

Advantages

This passive direct-attach copper cable offers low latency and stable signal integrity for short-distance links while eliminating the need for separate optical transceivers and patch cords. Its fixed length reduces installation complexity and helps maintain tidy cable management in dense rack environments. The cable is designed for immediate plug-and-play use with standard QSFP ports, providing a predictable electrical connection with minimal power consumption compared to active solutions.

Key specifications

How to use

Power down is not typically required for insertion or removal, but follow your equipment vendor’s hot-plug guidelines. Align and insert each QSFP connector into the corresponding port until it seats securely; ensure the latch or release mechanism engages if present. Route the cable to avoid sharp bends and mechanical strain, keeping the 0.5 m length free of kinks. For removal, depress the connector latch and pull straight out to avoid damaging the port. Verify link status on connected devices after installation.

Recommendations

Use this 0.5 m passive QSFP-to-QSFP cable for stable, low-latency links within racks or between adjacent racks. Avoid exceeding the recommended bend radius and protect the cable from excessive mechanical stress. Confirm compatibility with your network equipment vendor’s supported cable listings when planning deployments in mixed-vendor environments.
