DAC cable CBO MCP1700-B001E 30 m QSFP direct-attach copper

The DAC cable CBO MCP1700-B001E 30 m QSFP direct-attach copper is a fixed-length copper interconnect with QSFP connectors at both ends, intended for short-range, high-throughput links between QSFP-capable network devices. It provides a low-latency physical connection suitable for top-of-rack switches, server pairs and storage arrays in data centers and server rooms where a 30 m copper DAC is required. The cable is designed to deliver consistent signal integrity and plug-and-play operability with devices that accept QSFP direct-attach copper modules.

Advantages

This QSFP direct-attach copper cable offers reduced latency compared with optical transceivers and eliminate the need for separate transceiver modules and optical fiber patching for short distances. The fixed 30 m length simplifies installation planning and cable management in rack environments. The cable supports high-throughput links while keeping power consumption and total link cost lower than equivalent active optical assemblies for the same short-reach connections.

Suitable for

• Top-of-rack and leaf switches with QSFP ports
• Server-to-switch high-bandwidth connections
• Storage system interconnects in the same equipment room
• Short-reach aggregation links in data centers

Key specifications

• Connector type: QSFP to QSFP compatible direct-attach copper
• Length: 30 meters fixed copper assembly
• Cable media: Twinax copper suitable for short-reach, high-speed connections
• Latency: Low electrical latency characteristic of direct-attach copper links
• Power consumption: Passive/low-power design compared with optical transceivers (dependent on device support)

How to use

Insert each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring correct orientation and a secure latch. No separate transceiver configuration is required on most systems; the link should be recognized by network equipment that supports QSFP direct-attach copper modules. Verify link speed and status via device management interfaces and ensure that both endpoints are configured for the intended network parameters.

Usage recommendations

Install the 30 m DAC cable in cable trays or along rack sides to avoid sharp bends and mechanical strain; maintain the manufacturer’s minimum bend radius and avoid kinking. Use DAC cabling for short intra-rack or short inter-rack runs where QSFP copper connections are supported, and confirm compatibility with device vendor specifications before deployment.
