Καλώδιο Direct Attach (DAC) CBO Mellanox MCP2104-X04AB 10Gbps, 5 m

BlueOptics Direct Attach Cable (DAC) CBO Mellanox MCP2104-X04AB is a 5-metre passive twinax copper cable that provides 10 Gbps connectivity for short-reach links between SFP+ ports. The cable is intended for data centre and rack environments where reliable, low-latency connections are required between switches and servers or between servers. Its passive construction offers power-efficient operation and plug-and-play installation without additional transceivers.

Advantages

The DAC cable delivers low latency and stable 10 Gbps throughput for short-distance interconnects. Its twinax copper design reduces power consumption compared with active optical solutions and eliminates the need for separate optical transceivers, simplifying deployment. A 5-metre length supports flexible rack-to-rack or within-rack cabling while preserving signal integrity for SFP+ interfaces. The cable is compatible with common SFP+ ports and is designed for continuous operation in typical datacentre ambient conditions.

Suitable for

• Switch-to-server connections in rack or cabinet environments
• Server-to-server links for cluster and virtualization setups
• Switch-to-switch short-reach uplinks within racks or adjacent racks
• Environments requiring low-latency, power-efficient 10 Gbps links

Key specifications

• Connector type: SFP+ compatible twinax directly attached cable
• Data rate: 10 Gbps
• Length: 5 metres
• Cable medium: Passive twinax copper
• Typical use: Short-reach interconnects inside racks and between adjacent racks
• Latency: Low, suitable for performance-sensitive applications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your switch or server until the latch engages; no additional configuration is required for basic link operation. Ensure devices are powered and configured for the intended 10 Gbps link speed; check port settings and link negotiation if necessary. Route the cable to avoid tight bends and mechanical strain; secure with cable ties or management panels to maintain airflow and accessibility.

Recommendations

Use the cable for short-distance, high-bandwidth connections inside racks or between adjacent racks. Avoid sharp bends and prolonged mechanical stress on connectors. Confirm SFP+ port compatibility and firmware policies on network devices before installation to ensure full interoperability.
