Cavo Direct-Attach-Copper (DAC) CBO JNP-QSFP-DAC-3M 3 m, compatibile con Juniper QSFP

CBO JNP-QSFP-DAC-3M is a 3-meter Direct Attach Copper (DAC) cable compatible with Juniper QSFP ports, built to provide a reliable short-range high-speed connection between network devices. As a passive copper assembly, it eliminates the need for separate optical transceivers while supporting QSFP interfaces for switch-to-switch, switch-to-router and switch-to-server links within data center racks. The cable is intended for environments where low latency, predictable signal integrity and cost-effective cabling are priorities.

Advantages

This DAC cable offers a plug-and-play solution that reduces hardware complexity and power consumption compared with optical modules. The fixed 3 m length simplifies planning for top-of-rack and adjacent-rack connections and helps maintain consistent signal performance over short distances. Compatibility with QSFP ports ensures straightforward interoperability with Juniper-compatible equipment when used within the supported electrical specifications.

Suitable for

• Top-of-rack (ToR) switch interconnects in data centers
• Aggregation and spine-layer connections between network switches
• Direct server-to-switch or server-to-router links for high-throughput applications
• Short-reach links where low latency and reduced power usage are required

Key specifications

• Cable type: Direct Attach Copper (DAC), passive
• Connector interface: QSFP on both ends (compatible with Juniper QSFP ports)
• Length: 3 meters
• Use case: short-range, high-speed electrical interconnects
• Typical benefits: low latency, reduced power compared with optical transceivers

How to use

Install the DAC cable by inserting each QSFP connector into the corresponding QSFP port on the network devices until the connector latches. Ensure ports on both ends are powered off or live-swap capable according to the equipment manufacturer's guidance. Verify link status via the device management interface and monitor for proper link speed and lane configuration. Because this is a fixed-length passive copper cable, avoid excessive bending near the connector heads and route the cable to minimize mechanical strain.

Recommendations

Use this 3 m DAC cable for short interconnects inside racks or between adjacent racks. Confirm QSFP port compatibility and supported electrical specifications in your Juniper-compatible device documentation before deployment. Avoid routing the cable near high-interference electrical sources and maintain a bend radius consistent with vendor guidance to preserve signal integrity and mechanical life.
