Plan Reliable Data Center Links from Rack to Site
Compare DAC, AOC, pluggable transceivers and long-reach optical paths for leaf-spine fabrics, accelerated compute clusters and data center interconnects.
Network architectures
Start with the Network Architecture
The same data rate can require a different product family when the equipment, cable route, density or maintenance model changes.
0102Compute clusters
AI and High-Density Compute
Compare direct-attach and pluggable optical paths for dense compute clusters where cable volume, airflow and serviceability affect the design.
Compare DAC and AOC
03Inter-site links
Data Center Interconnect
Review distance, available fiber, connector path, optical budget and wavelength strategy before linking rooms, buildings or sites.
Review DCI opticsInterconnect paths
Compare the Link Before the Model
Use the route and operating priorities to narrow the product family. Exact reach, coding and interoperability still require model-level verification.
01
Passive copperDAC Assemblies
Best fit
In-rack and other very short links supported by the target equipment.
Commercial profile
Lower power draw and usually the lowest assembly cost for a supported short link.
- Supported length and lane map
- Cable bulk, bend radius and airflow
02
Active optical cableAOC Assemblies
Best fit
Rack-to-rack and row-level direct connections that need lighter optical cabling.
Commercial profile
Extends direct-attach reach beyond DAC while keeping a pre-terminated cable workflow.
- Port coding and FEC requirements
- Routing length and replacement workflow
03
Pluggable opticsTransceivers + Fiber
Best fit
Structured cabling, patch panels and links that benefit from replaceable modules.
Commercial profile
Adds separate modules and patching, but supports reusable fiber and flexible reach choices.
- Fiber type, connector and loss budget
- Module, switch and software compatibility
04
Long-reach opticalDCI and WDM Paths
Best fit
Inter-building or inter-site routes and projects with limited fiber availability.
Commercial profile
Supports longer routes or more capacity per fiber pair with additional planning and components.
- End-to-end optical budget
- Wavelength plan and equipment at both ends
Selection inputs
Information Needed for Model Selection
Record each physical link separately. A port speed alone does not confirm the reach, media, breakout, coding or environmental requirements.
Check Compatibility- 01
Platform
Switch, server NIC or adapter model, software version and target port.
- 02
Data path
Required speed, lane count, breakout direction and FEC mode.
- 03
Physical route
Rack, row, room or site distance, plus the intended cable route.
- 04
Fiber plant
Single-mode or multimode fiber, connector, polarity and patch-panel path.
- 05
Operations
Airflow, bend radius, serviceability, monitoring and replacement preference.
- 06
Project supply
Quantity, destination, delivery timing and required approval documents.
