FAQ About 100G DAC Cable
A 100G QSFP28 Direct Attach Copper (DAC) cable is a high-speed, cost-effective solution for short-distance data transmission. It utilizes a passive copper twinax cable with QSFP28 connectors on both ends, enabling direct connections between networking equipment such as switches, routers, and servers. This type of cable is ideal for data centers requiring low latency and low power consumption.
100G QSFP28 DAC cables offer several benefits for data center applications:
Low Latency: Provides near-zero latency, essential for high-performance computing environments.
Cost-Effective: Eliminates the need for transceivers, reducing overall infrastructure costs.
Energy Efficient: Consumes less power compared to optical transceivers, aiding in energy savings.
Ease of Deployment: Simplifies installation with plug-and-play capability.
These features make 100G QSFP28 DAC cables a preferred choice for short-range, high-speed connections in modern data centers.
Yes, 100G QSFP28 DAC breakout cables are designed for such applications. These cables split a single 100G QSFP28 port into four 25G SFP28 ports, facilitating connections between high-speed aggregation switches and lower-speed access devices. This setup is commonly used in data centers to optimize bandwidth utilization and network scalability.
The maximum length of a 100G QSFP28 DAC cable typically ranges up to 5 meters, depending on the cable’s gauge and quality. For distances beyond this range, Active Optical Cables (AOCs) or transceiver modules with fiber optic cables are recommended to maintain signal integrity and performance.
