6.4T+ CPO
Industry leading integration / high channel density
– 16 (6.4T) and 32 (12.8T) lanes, higher channel count for on-board (OBO) and co-packaged optics (CPO)
Driver integration
– Optimization of signal path, RF performance, drive voltages for outstanding RF performance and form factor
Less system power
– Leading power dissipation architecture with less than 200 mW per lane and 0.5 pJ/bit, with a roadmap for further reduction
Outstanding signal integrity
– Improved signal integrity (1E-6 bit error rate) and quantitatively better eye diagrams
