Why Copper? Benefits of RJ45 for 100GbE
- Cost-Efficient Deployment: Uses widely available copper cables
- Simplified Cabling: No need for fiber optics or transceivers
- Ease of Integration: Compatible with existing RJ45 network switches
- Reduced Complexity: Ideal for rack-to-rack and Top-of-Rack (ToR) setups
The E810-CQDA2T is one of the few 100GbE solutions offering RJ45, delivering Intel-grade performance without the fiber-related overhead.
