DAC cable CBO MCP1600-C001E30N 30 m QSFP28 direct-attach copper

BlueOptics DAC cable CBO MCP1600-C001E30N 30 m QSFP28 direct-attach copper is a 30‑meter direct‑attach copper interconnect compatible with QSFP28 ports. Designed for server, switch and storage connectivity in data centers, this cable offers a wired solution for short to medium reach links where low latency and reliable throughput are required. The assembly uses a QSFP28 form factor on both ends to match QSFP28 equipment and to provide straightforward integration into rack-to-rack and top-of-rack deployments.

Advantages

The direct-attach copper construction delivers low end-to-end latency and consistent signal integrity over its 30 m length while eliminating the need for optical transceivers. The QSFP28 compatibility ensures standardized mechanical and electrical interfaces for high-speed 100 Gbps links, and the fixed cable assembly simplifies installation and cable management. The passive/active copper design reduces power consumption compared with optical alternatives and provides a cost-effective option for short to medium reach connections.

Suitable for

• Rack-to-rack 100 Gbps connections in data center rows
• Top-of-rack aggregation to core switches using QSFP28 ports
• High-bandwidth interconnects between servers and storage arrays
• Low-latency links for HPC clusters and virtualization hosts

Key specifications

• Connector type: QSFP28 on both ends
• Length: 30 meters
• Supported data rate: up to 100 Gbps per link (QSFP28 specification)
• Medium: direct-attach copper cable
• Typical use: short to medium reach data center interconnects
• Latency: low, characteristic of copper passive/active DAC assemblies

How to use

Install the cable by aligning each QSFP28 plug with the corresponding QSFP28 port on network devices and insert until the connector latch engages. Verify link status via device LEDs or management interfaces and configure the ports according to the switch or host network settings. For mixed environments, ensure both endpoints support QSFP28 and the intended 100 Gbps configuration. Route the cable through cable management paths to prevent excessive bending and to maintain airflow in the rack.

Recommendations

Handle the cable by the connector housings and avoid sharp bends; maintain the manufacturer’s minimum bend radius to prevent damage. Use proper strain relief and routing to reduce mechanical stress, and verify firmware and port compatibility on both ends before deployment. For distances near the 30 m limit, confirm link stability under expected environmental and traffic conditions.
