SFP+ DAC cable CBO MCP2103-X04AB 10Gbps, 5 m passive direct-attach copper

The SFP+ DAC cable CBO MCP2103-X04AB 10Gbps, 5 m passive direct-attach copper is a fixed-length direct-attach solution for short-reach 10 Gigabit Ethernet links. This passive SFP+ cable is designed to plug directly into SFP+ ports on switches, servers and storage devices, delivering a low-latency, energy-efficient 10Gbps connection over a 5 metre copper assembly. It is intended for in-rack and rack-to-rack interconnects in data centres and network closets where a compact, cost-effective link without separate optical transceivers is required.

Advantages

The cable offers a reliable 10 Gbps physical link with minimal latency and reduced power consumption compared with active optics. Its fixed 5 m length simplifies inventory and cabling plans while eliminating the need for separate SFP+ transceivers, reducing overall component count and cost. The direct-attach design provides a straightforward mechanical fit into standard SFP+ ports and is compatible with common switch and server form factors used in dense rack deployments.

Suitable for

• Short-range server-to-switch or switch-to-switch interconnects within the same rack or adjacent racks
• Storage array connections requiring 10Gbps throughput
• High-density network topologies in data centres and network closets

Key specifications

• Interface type: SFP+ direct-attach copper (DAC)
• Data rate: 10 Gbps
• Length: 5 metres (fixed)
• Cable type: Passive twinax copper assembly
• Connector: SFP+ plug on both ends
• Typical use range: Short-reach (in-rack / adjacent racks)

How to use

Install the SFP+ connectors into the SFP+ ports on the devices to be linked, ensuring both ends are fully seated and retaining clips engage. Verify port configuration and speed settings on each switch or server and ensure firmware or driver compatibility where required. Because this is a passive direct-attach cable, no separate transceivers or power connections are necessary; the link becomes active once both ports are enabled and negotiated at 10 Gbps.

Recommendations

Use the cable for short-distance connections within racks or between immediately adjacent racks to ensure signal integrity and to benefit from low latency and reduced power consumption. Avoid routing near high-power electrical sources or placing excessive strain on the cable; maintain the manufacturer’s minimum bend radius and secure cables to prevent mechanical stress.
