DAC

DAC (Direct Attach Cable, a type of cable for direct connection) are a high-speed, short-distance, and cost-effective solution for interconnecting data centers. DAC is a copper cable with electrical interfaces (such as SFP+, QSFP28, etc.) fixed at both ends. It transmits data using electrical signals of copper conductors without the need for photoelectric conversion.

Applications:

Low EMI radiation Switches, servers and routers

Data Center

Storage area networks

Telecommunication and wireless infrastructure

Features:

High conversion rate and low latency

Compliant with SFF-8431, 8432 and 8472

Up to 7m transmission

Temperature Range: 0°C to 70°C

RoHS compliant

Ultra-low cost: Optical-free devices, the cost is much lower than that of AOC or optical module solutions.
