Suitable for server-to-switch and switch-to-switch interconnects in data centers and rack environments.

## Long description

BlueOptics Direct Attach Copper (DAC) Cable CBO 3 m QSFP is a 3‑meter passive copper interconnect engineered for QSFP ports on compatible Juniper network equipment. Designed for short-range, high-speed links in data center racks, this DAC cable provides a direct electrical connection between QSFP-enabled devices. The cable delivers low latency and low power consumption compared with optical transceivers, making it suitable for dense, cost-sensitive deployments where distances do not require fiber optics.
Advantages
The CBO 3 m QSFP DAC offers reliable signal integrity for short links while eliminating the need for separate transceivers and optical modules. Its passive copper design reduces power draw and heat output in rack environments. The fixed-length cable simplifies installation and port management, and compatibility with Juniper QSFP ports ensures straightforward integration into existing switch and server topologies.
Suitable for
Server-to-switch connections within the same rack or adjacent racks
Switch-to-switch uplinks in top-of-rack and leaf-spine architectures
Short-range high-bandwidth links in data center and colocation environments
Environments where reduced power usage and latency are priorities
Key specifications
Connector type: QSFP-to-QSFP
Cable type: Passive direct attach copper
Length: 3 meters
Applications: Short-range high-speed data center interconnects
Typical benefits: Low latency, low power consumption, simplified port management
How to use
Inspect QSFP ports on both devices for compatibility and available lanes before connecting. Align the QSFP connectors and insert the cable until the latches engage; ensure both ends are properly seated. Verify link status via device LEDs or management interfaces. For removal, depress the connector latch and pull the cable straight out to avoid stressing the connector. Do not bend the cable sharply; maintain gentle radius bends to preserve signal quality.
Usage recommendations
Use the DAC cable for short, high-bandwidth connections where passive copper is supported by both endpoints. Avoid extended runs beyond the specified 3 m length and ensure adequate airflow around rack equipment to mitigate any localized heating. Confirm firmware and hardware compatibility with Juniper device documentation for optimal link negotiation and performance.
