DAC kábel CBO BlueLAN Mellanox CP1700-B001E 1 m pasívny Direct-Attach medený

Passive 1 metre Direct-Attach Copper (DAC) cable CBO BlueLAN Mellanox CP1700-B001E provides a short-range, high-speed copper connection for Mellanox-compatible ports. This fixed-length cable eliminates the need for separate transceivers, offering a compact and reliable link for within-rack or rack-to-rack interconnects. The cable is suitable for environments that require low-latency connectivity and straightforward installation in network switches, storage systems and server top-of-rack setups.

Advantages

The passive DAC design delivers low latency and predictable electrical characteristics without additional power or active components. A 1 m fixed length reduces clutter and signal loss associated with longer patching, while the direct-attach format simplifies installation and maintenance. Compatibility with Mellanox-style ports ensures broad interoperability in data centre environments and helps minimize deployment time.

Suitable for

• Short-range connections between switches and servers within the same rack
• Rack-to-rack links in tightly routed data centre topologies
• High-throughput storage system interconnects with low-latency requirements
• Environments where simplicity and reduced power consumption are priorities

Key specifications

• Cable type: Passive Direct-Attach Copper (DAC)
• Length: 1 metre
• Connector style: Direct-attach compatible with Mellanox-style ports
• Use case: Short-range, high-speed interconnects for data centre equipment
• Latency: Designed for low-latency electrical signalling
• Power: Passive operation, no external power required

How to use

Insert each connector into the corresponding Mellanox-compatible port on the devices to be connected until the connector latches securely. Ensure ports are powered down or follow hot-plug procedures recommended by your hardware vendor if required. Route the cable to avoid sharp bends and mechanical stress; secure with cable management accessories if necessary. After connection, verify link status and negotiated speed in the device management interface.

Recommendations

Use this 1 m passive DAC for short, direct links in dense rack deployments where low latency and simplicity are required. Avoid exceeding bend radius limits, and deploy in clean, temperature-controlled rack spaces. For longer runs or fibre-based topologies consider appropriate active or optical alternatives.
