Frequently Asked Questions
What is a 400GBASE-CR8 QSFP-DD direct attach cable used for?
A 400GBASE-CR8 QSFP-DD DAC is used for high-speed Ethernet connections in data centers, connecting switches to servers, storage systems, and network appliances. The passive copper design makes it ideal for short-distance links where cost efficiency and low latency are critical.
How does a passive copper DAC compare to active optical cables?
Passive copper direct attach cables offer lower cost, zero power consumption, and minimal latency compared to active optical solutions. They're perfect for short-reach deployments (typically under 10 meters) where the signal integrity remains strong without active signal conditioning.
Is the ENET 400GBASE-CR8 cable compatible with existing 400G infrastructure?
Yes, this QSFP-DD cable is fully compatible with standard 400G Ethernet equipment supporting the 400GBASE-CR8 specification. It works seamlessly with enterprise switches, routers, and network interface cards featuring QSFP-DD ports.
What is the maximum recommended distance for this 1.5M QSFP-DD cable?
The 1.5-meter length is optimized for short-reach data center interconnects. Passive copper cables maintain signal integrity up to approximately 10 meters depending on environmental conditions, making this length ideal for top-of-rack and adjacent equipment connections.
