Frequently Asked Questions
What is a 100G-CR4 QSFP28 DAC cable used for?
The 100G-CR4 QSFP28 DAC cable is used for high-speed data connections in data centers and enterprise networks. It connects Cisco switches, servers, and storage systems over short distances (typically up to 10 meters), providing 100 Gbps throughput without the cost of optical transceivers.
Is the UNC Group 100G-CR4 cable compatible with Cisco equipment?
Yes, this QSFP28 DAC cable is fully compatible with Cisco networking equipment that supports 100G-CR4 connections. It works with Cisco Nexus switches and other standards-compliant devices featuring QSFP28 ports.
What are the advantages of passive copper DAC cables over active cables?
Passive copper DAC cables offer lower cost, zero power consumption, minimal latency, and greater reliability compared to active cables. They require no external power source and are ideal for short-distance connections within data centers.
Can I use this 0.5M cable for longer distances?
The 0.5M length is optimized for short-distance rack-to-rack and switch-to-server connections. For longer distances, consider active cables or optical solutions that support extended reach while maintaining signal integrity.
