CBO SFP28 Passive DAC Cable 3 m 25 Gbit/s Male-to-Male, model MCP2M00-A003E30L-BL

CBO SFP28 Passive DAC Cable 3 m 25 Gbit/s Male-to-Male (model MCP2M00-A003E30L-BL) is a Direct Attach Copper (DAC) assembly designed for short-reach, high-speed connections in data center and rack environments. The 3-metre fixed-length copper cable integrates two male SFP28 connectors to provide a compact, low-latency link between switches, network interface cards (NICs) and servers. It supports 25 Gbit/s per lane throughput and is intended for point-to-point connections where distance is limited and power-efficient, cost-effective cabling is required.

Advantages

This passive SFP28 DAC cable delivers low latency and power consumption compared with active optical alternatives, offering plug-and-play interoperability with SFP28 ports. Its fixed 3 m length and molded male-to-male connectors simplify installation in dense rack configurations, reducing cabling bulk. The copper assembly provides reliable electrical performance for short links and eliminates the need for separate transceivers and fiber patch cords, supporting predictable signal integrity for 25 Gbit/s data rates.

Suitable for

• Top-of-rack and middle-of-row switch-to-switch connections
• Server to NIC or server to switch links within the same rack
• High-density patching in data centers and lab environments
• Short-reach 25 Gbit/s point-to-point interconnects

Key specifications

• Cable type: Direct Attach Copper (passive)
• Connector type: Male-to-male SFP28
• Length: 3 metres
• Data rate: 25 Gbit/s
• Form factor: SFP28 compatible modules at both ends
• Typical use: Short-reach, point-to-point interconnects in racks and data centers

How to use

Install the DAC cable by inserting each male SFP28 connector into the corresponding SFP28 port until it latches. Ensure both devices are powered down or follow hot-plug guidance from the equipment manufacturer when connecting live systems. Verify that the host equipment recognizes the link and negotiates 25 Gbit/s operation. Route the cable to avoid sharp bends and mechanical strain; the fixed-length assembly requires minimal management in short-reach deployments.

Recommendations

Use this passive DAC cable for interconnections within a single rack or adjacent racks where distances do not exceed 3 metres. Avoid routing near strong EMI sources and maintain bend radii compliant with the cable’s mechanical limits. For longer distances or when optical isolation is required, consider active optical solutions or fiber transceivers instead.
