FAQ About 200G QSFP56 DAC cable

What is a 200G DAC cable and how does it work?

A 200G DAC cable (Direct Attach Copper cable) is a high-speed, cost-effective solution for short-range data center interconnects. It uses copper wiring to connect switches, servers, or routers, supporting 200G Ethernet speeds. The QSFP56 DAC cable integrates QSFP56 connectors, ensuring low latency and high reliability for applications like data center networking and high-performance computing.

What are the benefits of using a 200G QSFP56 DAC cable over AOC?

A 200G QSFP56 DAC cable offers several advantages over Active Optical Cables (AOC):

Cost-effective: Lower cost for short distances (up to 7m).
Low power consumption: Passive DACs use minimal power compared to AOCs.
Durability: Copper cables are robust for data center interconnects. For short-range connectivity (e.g., within racks), DACs are ideal, while AOCs suit longer distances.

What lengths are available for 200G QSFP56 DAC cables?

Our 200G QSFP56 DAC cables are available in various lengths, including 1-meter 200G DAC cable, 3-meter 200G DAC cable, and 5-meter 200G DAC cable. Passive cables support up to 3-5 meters, while active DACs can reach 7 meters for data center short-range connectivity. Contact us for custom lengths.

What are the key benefits of using the 200G QSFP56 DAC cable in high-performance data centers?

The 200G QSFP56 DAC cable provides low-latency, high-speed connectivity, ideal for server-to-server connections in data centers and cloud computing environments.

Can a 200G QSFP56 DAC cable be used for switch-to-switch connectivity?

Absolutely. The 200G QSFP56 DAC cable is perfect for switch-to-switch connectivity in data centers. Its 200G Ethernet support ensures high bandwidth for connecting switches like NVIDIA Spectrum-3 or Arista 7800R, enabling efficient data center networking solutions.

How do I choose between passive vs. active 200G DAC cables?

Passive 200G DAC cables: Best for distances up to 3-5 meters, offering lower cost and power efficiency.
Active 200G DAC cables: Support up to 7 meters with enhanced signal integrity for longer data center interconnects. Choose based on your data center cabling needs and distance requirements.
