Key Advantages of AOC & DAC Connectivity
Simplified Infrastructure & Deployment
Eliminates separate optics and patch cables, reducing components, simplifying routing
and improving overall deployment speed and efficiency.
Lower Total System Cost
Reduces hardware, installation labor and overall infrastructure cost compared to
separate optics and cabling.
Plug-and-Play Efficiency
Pre-configured assemblies install quickly and support hot-swappable replacement
without network disruption.
Consistent, Reliable Performance
Integrated design ensures predictable signal integrity and polarity consistency while
reducing connection points and potential failure interfaces.
Flexible Breakout & Multi-OEM Compatibility
Supports 800G to 2×400G and 4×200G breakouts while enabling interoperability
across leading OEM platforms, including mixed OEM compatibility on either end.
Advanced In-System Testing and Validation
Proficium 800G AOCs and DACs are built to meet or exceed OEM performance and quality standards and are 100% system-level tested for compatibility prior to shipment. Solutions undergo in-system validation across leading platforms including Arista, Cisco, Dell, Juniper and NVIDIA, while adhering to applicable MSA specifications for seamless multi-vendor interoperability.
Testing and validation capabilities include:
- In-system validation within live switch environments
- Bit error rate testing, eye diagram analysis and signal integrity evaluation
- Power, thermal and performance validation under real operating conditions
- Compliance testing across Ethernet and InfiniBand architectures
Selecting the Right Interconnect
Choosing the right cable type depends on distance, power requirements and deployment density. Proficium provides AOC, DAC and ACC solutions to optimize connectivity across AI and hyperscale environments.
Best for ultra-short reach, high-efficiency connections
- Ideal for intra-rack and top-of-rack deployments
- Ultra-low latency performance
- Most cost-effective for short distances
- Typical reach up to ~1–3 meters
Best for extended copper reach
- Extends reach beyond passive DAC
- Maintains lower cost and power vs optical solutions
- Ideal for short rack-to-rack connectivity
- Typical reach up to ~3–7 meters
Best for longer reach and flexible routing
- Lightweight and easier cable management
- Reduced signal loss over distance
- Ideal for row-to-row and cluster interconnects
- Supports extended reach beyond copper solutions
