FAQ About 25G Direct Attach Cables
A 25G DAC (Direct Attach Cable) is a passive Twinax cable with SFP28 connectors, used for short-range, high-speed data center connections.
DAC cable are more cost-effective for <5m, while AOC cable suit longer distances.
A wholesale 10G 25G SFP28 DAC cable offers cost-effective, pre-terminated connectivity with fixed low latency and power consumption, making it perfect for data centers and hyperscale environments. Buying in bulk reduces per-unit costs and simplifies inventory management without sacrificing the reliability and performance that enterprise networks demand.
A DAC cable 25G delivers up to 25 Gbps of full-duplex bandwidth with minimal signal loss over short distances (typically up to 5 m), outperforming legacy copper solutions in both speed and electromagnetic interference immunity. Its direct-attach design also eliminates the need for separate transceiver modules, reducing overall power draw and heat generation.
When choosing a 25G SFP28 DAC cable, ensure compatibility with your switch’s SFP28 ports and verify the maximum supported length (usually 1 m to 5 m). Look for industry-standard cable grades (e.g., SFF-8402) and reputable brands that guarantee end-to-end validation and consistent performance across high-density rack deployments.
China 10G 25G SFP28 DAC cable manufacturers often offer highly competitive pricing and rapid production turnaround, making them a smart option for projects with tight budgets or aggressive timelines. Many Chinese suppliers also adhere to global quality standards (CE, RoHS) and provide extensive testing reports to ensure each cable meets or exceeds OEM specifications.
