CBO DAC Cable QSFP-4X10G-C1M 4x10G 1m passive direct attach cable for QSFP ports

CBO DAC Cable QSFP-4X10G-C1M is a 1 m passive direct attach copper (DAC) cable that delivers four independent 10 Gb/s lanes through a QSFP connector. It is designed for short-reach interconnects between devices with QSFP ports, providing high-throughput, low-latency links with minimal setup and reduced power consumption compared with active transceivers. The cable is suitable for rack-to-rack and intra-rack connections in data centers and for connecting switches, routers and servers that support QSFP interfaces.

Advantages

The passive DAC cable provides stable, high-bandwidth connections with low latency and no need for external power or configurable optics. Its fixed length and integrated QSFP connectors simplify installation and reduce compatibility checks. Compared with optical modules, the cable lowers power draw and total cost for short-distance links while maintaining consistent signal integrity for four 10 Gb/s lanes.

Suitable for

• Short-reach connections between switches and routers with QSFP ports
• Server-to-switch links in rack and top-of-rack deployments
• High-density patching inside data center racks
• Low-latency connections for virtualization and storage traffic

Key specifications

• Transmission lanes: 4 × 10 Gb/s
• Connector type: QSFP (quad small form-factor pluggable)
• Length: 1 metre (fixed)
• Cable type: Passive direct attach copper (DAC)
• Typical use: Short-reach, intra-rack and rack-to-rack interconnects

How to use

Insert each QSFP connector into the corresponding QSFP port on the network devices until the connector latches. Ensure both devices are powered and their ports support passive QSFP direct attach cables at 4×10 Gb/s. No additional configuration is typically required; the devices will negotiate link parameters automatically. Avoid bending the cable beyond manufacturer-recommended minimum bend radius and route it to prevent strain on connectors.

Usage recommendations

Use this 1 m passive DAC cable for short-distance connections inside racks or between adjacent racks where QSFP interfaces are supported. Verify port compatibility and supported lane speeds on connected devices before installation. Store and handle the cable to avoid sharp bends and mechanical stress to preserve signal integrity and connector reliability.
