Co-Packaged Optics

Diamond Solutions
for CPO

Ultra-high thermal conductivity diamond substrates for next-generation Co-Packaged Optics. Matching industry-standard dimensions for 51.2T to 102.4T switching systems.

Why Diamond for CPO?

Co-Packaged Optics place optical engines directly adjacent to switch ASICs, creating extreme thermal challenges that diamond solves.

2,000+ W/m·K Thermal Conductivity

15x better than copper. Instantly spreads heat from densely integrated optical engines and switch ASICs.

Sub-0.1K Temperature Uniformity

Critical for maintaining optical alignment in co-packaged modules. Eliminates thermal gradients across switch dies.

Custom Dimensions

Match industry-standard CPO component sizes. From 15mm laser submounts to 100mm switch baseplates.
