Add-On ADD-Q4CIQ4JU-P1M 400G DAC Cable

Overview

The Add-On ADD-Q4CIQ4JU-P1M is a 400Gbps Direct Attach Copper (DAC) cable, engineered to provide a cost-effective, low-latency interconnect for high-density data center networking. This passive copper cable is designed for short-reach applications, directly connecting network devices within racks or adjacent racks, minimizing signal degradation and power consumption compared to active optical modules. It solves the need for reliable, high-bandwidth links between compatible switches and servers in environments demanding maximum throughput.

Compatibility

This cable is specifically designed as a compatible replacement for the Juniper Networks QDD-400G-DAC-1M. It ensures seamless integration with Juniper QFX series switches and other networking equipment that utilize QSFP-DD (Quad Small Form-factor Pluggable Double Density) ports and support 400GBASE-CR4 standards. Verify your equipment's QSFP-DD port specifications for 400Gbps DAC compatibility.

Installation Notes

The ADD-Q4CIQ4JU-P1M features integrated QSFP-DD connectors that snap securely into place. Ensure the port latches are fully engaged for a stable connection. For optimal performance and to prevent accidental disconnection, maintain a gentle bend radius and avoid sharp kinks in the cable. This passive cable requires no power input.
