Beyond Plugables.

At **1.6T per port**, the electrical signals between a switch ASIC and a traditional plugable transceiver (like OSFP) become extremely difficult to manage. The signal attenuation over even just a few centimeters of PCB trace is massive, requiring power-hungry DSPs (Digital Signal Processors) in every module.

**Co-Packaged Optics (CPO)** solves this by placing the optical engines directly on the same substrate as the ASIC. This reduces the 'reach' of the electrical signal to millimeters, allowing for higher density and significantly lower picojoules-per-bit (pJ/bit).

Higher Density

Removes the front-panel air flow restriction of modules, allowing systems to pack 51.2T or 102.4T into a single 1U-2U rack unit.

Power Paradox

Saves 5-10 Watts per port by eliminating the DSP. For a 32-port switch, that's 320W of savings just on optics.
