Frequently Asked Questions
What is a 100G direct attach cable used for?
A 100G direct attach cable connects high-speed network equipment like switches and servers in data centers. The Ubiquiti QSFP28 cable provides low-latency, cost-effective connectivity for short-distance links without requiring separate transceiver modules.
Is the QSFP28 cable compatible with QSFP+ equipment?
Yes, the Ubiquiti 100G Direct Attach Cable supports both QSFP28 and QSFP+ interfaces, offering backward compatibility with existing 40 Gbps infrastructure while enabling 100 Gbps performance on newer equipment.
Why choose a 0.5-meter direct attach cable?
The 0.5-meter length is ideal for short-distance interconnects within server racks and adjacent equipment. This compact size reduces cable clutter, improves airflow in data centers, and maintains signal integrity for maximum performance.
Does this cable require external transceivers?
No. The Ubiquiti 100G Direct Attach Cable is a passive cable that connects directly between QSFP28 ports, eliminating the need for transceivers and reducing overall system complexity and cost.
