Direct Attach Cable (DAC) CBO MCP2103-X004B 10Gbps 24m passive twinax

CBO DAC MCP2103-X004B 10Gbps 24m passive twinax is a 24-metre direct attach copper cable designed to provide a fixed, low-latency 10 Gigabit Ethernet link between compatible SFP+ ports. The cable is intended for short- to mid-range interconnects and offers a cost-effective alternative to optical transceivers and fiber patching where copper twinax is supported. It supports standard 10Gbps data rates and is suitable for use between switches, network interface cards and servers in data centre and enterprise wiring topologies.

Advantages

The passive twinax construction delivers low latency and predictable electrical performance across the full 24 m length without the need for external power or active components. The cable is plug-and-play with compatible SFP+ ports, reducing installation complexity and overall link cost compared with optics and fiber transceivers. Its fixed-length copper design simplifies cable management and provides a robust physical connection that is resistant to typical handling in rack environments.

Suitable for

• 10Gbps short- to mid-range connections between switches
• Direct server-to-switch or server-to-server links using SFP+ ports
• Top-of-rack and middle-of-row cabling in data centres
• High-density patching scenarios where cost-effective copper links are required

Key specifications

• Data rate: 10 Gbps
• Length: 24 metres
• Cable type: Passive twinax (direct attach copper)
• Connector type: SFP+ compatible ends
• Latency: Low, fixed electrical latency typical for copper twinax
• Use environment: Rack and data centre interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the networking devices until the latch engages. Ensure both devices are powered down or follow hot-plug guidance from the equipment manufacturer when adding or removing direct attach cables. Verify link status on both devices and configure link settings as required by the network equipment (for example flow control, speed auto-negotiation or fixed speed settings). For reliable operation, avoid excessive bends and maintain recommended bend radius for copper twinax assemblies.

Recommendations

Use this passive twinax cable where SFP+ copper direct attach is supported by both endpoints and where a 24 m fixed-length copper link meets topology and performance needs. Avoid using this cable beyond the specified length or in environments requiring extended reach or optical isolation. For mixed vendor environments, confirm SFP+ compatibility and any host-side restrictions prior to deployment.
