Copper Interconnect vs Optical Interconnect
A comparison of electrical and optical connectivity for data movement in AI infrastructure.
| Research field | Copper Interconnect | Optical Interconnect |
|---|---|---|
| What it is | Electrical data movement through traces, cables, retimers, and active electrical links. | Data movement through optical modules, fibers, lasers, and photonic components. |
| Why it matters | Copper can be economical and practical over short reaches. | Optical becomes more important as distance, bandwidth, and power constraints increase. |
| Where it is used | Inside servers, racks, and short-reach connections. | Rack-to-rack, switch-to-switch, and higher-bandwidth data center links. |
