DAC cable CBO OCTTAPCABLE1M 1m QSFP direct attach copper cable

Direct Attach Copper (DAC) cable CBO OCTTAPCABLE1M 1m QSFP direct attach copper cable by BlueOptics is a 1 metre passive copper assembly engineered for short-reach, high-speed interconnects between QSFP ports. The cable provides a compact, low-latency physical connection for QSFP-enabled switches, routers and servers without the need for separate transceiver modules. Designed for data centre top-of-rack and aggregation links, this 1 m QSFP DAC offers a simple, reliable option where compatibility with QSFP ports is met.

Advantages

This QSFP direct attach copper cable delivers low electrical latency and predictable performance for short-distance links while avoiding the power consumption and cost of hot-pluggable optics. Passive copper construction keeps the design simple and robust for rack-to-rack and intra-rack connections. The one-metre length minimises excess cable management and helps maintain clean airflow in densely populated equipment racks.

Suitable for

• Short-reach connections between QSFP ports on switches and routers
• Server uplinks to QSFP-enabled switches in top-of-rack installations
• Aggregation links within data centre racks and small clusters
• Environments requiring low-latency, power-efficient copper interconnects

Key specifications

• Connector type: QSFP to QSFP passive copper assembly
• Cable length: 1 metre
• Transmission medium: Direct attach copper (passive)
• Intended use: Short-reach, high-speed interconnects (QSFP ports)
• Typical applications: Top-of-rack and aggregation cabling in data centres

How to use

Install the cable by firmly inserting each QSFP connector into the corresponding QSFP port until the connector latches. Verify that both connected devices recognise the link and that link LEDs or management interfaces indicate a stable connection. Use cable routing and management hardware to avoid sharp bends and mechanical strain; the short 1 m length is intended for direct rack-to-rack or module-to-module connections. If the device requires port activation or configuration for the QSFP link, follow the hardware vendor's guidelines to enable the interface.

Recommendations

Use this 1 m QSFP DAC for short, fixed links where passive copper meets the required data rate and compatibility. Avoid routing the cable near high-EMI sources and keep bend radius within manufacturer guidance to preserve signal integrity and connector life.
