Direct Attach Cable (DAC) CBO MCP2100-X005B 10Gbps, passive SFP+, 24 m

The Direct Attach Cable (DAC) CBO MCP2100-X005B 10Gbps, passive SFP+, 24 m is a fixed twinax copper assembly for short‑reach 10 Gigabit Ethernet connections. This passive SFP+ cable provides a direct electrical interface for devices equipped with SFP+ ports and is intended for reliable rack‑to‑rack, switch‑to‑switch and server uplink links where a 24 metre reach is required. The design emphasises deterministic latency, low power consumption and a compact form factor that fits standard SFP+ ports without additional transceivers.

Advantages

This passive SFP+ DAC offers a cost‑effective alternative to optical transceivers and fibre cabling for short distances, eliminating the need for separate modules. Its fixed 24 m length simplifies inventory and cable management in data centre topologies. The twinax copper construction provides low latency and stable signal integrity for 10Gbps throughput while avoiding the power draw associated with active modules. The integrated SFP+ connector housings ensure compatibility with standard SFP+ cages and support plug‑and‑play deployment where host devices accept passive DACs.

Suitable for

• Rack‑to‑rack connections in data centre environments
• Switch‑to‑switch interconnects within the same room or row
• Server uplinks to top‑of‑rack and end‑of‑row switches
• High‑density 10GbE installations requiring fixed‑length copper cabling

Key specifications

• Interface: SFP+ to SFP+ (passive)
• Data rate: 10 Gbps
• Cable type: Twinax copper
• Length: 24 metres
• Form factor: Direct attach cable with integrated SFP+ connector housings
• Power: Passive operation (no external power required)
• Typical use: Short‑reach, rack and server interconnects

How to use

Insert each SFP+ connector into the SFP+ cage of the two devices you intend to connect, ensuring a secure latch. Verify that the host devices support passive DACs and that link ports are configured for 10Gbps operation. The cable is plug‑and‑play in supported systems; once fitted, confirm link status via device LEDs or management interfaces. Avoid sharp bends and maintain recommended bend radius for twinax copper to preserve signal performance.

Recommendations

Install the cable in environments free from excessive mechanical stress or tight bend radii and avoid prolonged exposure to temperatures outside device specifications. Use in clean, dust‑controlled data centre areas and label both ends for easier maintenance and troubleshooting. Confirm compatibility with your switch or server vendor’s supported DAC list when deploying in managed or vendor‑restricted systems.
