Cabo Direct Attach (DAC) CBO 10Gbps Mellanox MCP2103-X005B 5 m

Direct Attach Cable (DAC) CBO 10Gbps Mellanox MCP2103-X005B 5m is a passive SFP+ copper twinax cable that provides 10Gbps point-to-point connectivity over a 5-metre length. The cable is designed for short-range interconnects between switches, servers and network adapters that support SFP+ ports. It requires no additional optical transceivers or modules, offering plug-and-play installation for rack-to-rack or intra-rack links where low latency and reliable 10Gbps throughput are required.

Advantages

The passive DAC offers low latency and consistent 10Gbps performance with minimal power consumption compared with active optical solutions. Its pre-terminated twinax construction simplifies installation and reduces space requirements in dense rack environments. Compatibility with Mellanox-compatible SFP+ ports ensures straightforward interoperability for systems that accept standard SFP+ direct-attach cables.

Suitable for

• Short-distance connections between network switches
• Server-to-switch links within the same rack or adjacent racks
• High-density rack environments requiring low-latency 10Gbps links
• Top-of-rack (ToR) aggregation and access layer connections

Key specifications

• Interface: SFP+ to SFP+
• Data rate: 10 Gbps
• Length: 5 m
• Cable type: Passive twinax copper
• Use case: Short-range, direct attach interconnect
• Latency: Low (typical for passive copper DAC)

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the two devices until the latch clicks. Ensure both devices are powered and configured to enable their SFP+ ports. No additional transceivers or fiber patching is required. Verify link status and speed through the device management interface or LED indicators and confirm the connection is negotiated at 10Gbps.

Recommendations

Use this 5 m passive SFP+ cable for short intra-rack or adjacent-rack links where a reliable, low-latency 10Gbps connection is needed. Avoid sharp bends and excessive tension on the cable; maintain appropriate airflow and cable management in dense racks. Confirm SFP+ port compatibility with device documentation before installation.
