Broadband Interconnect Validation

Validating artificial intelligence (AI) data center interconnects operating at 448 gigabits per second and evolving toward 1.6 terabits per second requires broadband characterization of transmission channels across a continuous frequency range extending to 250 GHz. The measurement configuration includes a vector network analyzer, broadband frequency extenders, a test set controller, precision calibration standards, and fixtures or connectors to characterize insertion loss, return loss, group delay, differential transmission characteristics, and impedance behavior across copper and optical interconnect technologies. Measurements are performed on channels, connector transitions, cable assemblies, printed circuit board structures, and co-packaged optical interfaces to understand how each element contributes to channel performance before hardware integration.

The resulting broadband scattering parameter measurements are used to generate accurate channel models for simulation and compliance verification. Engineers can export measured data into signal integrity tools to evaluate equalization techniques, eye opening, insertion loss budgets, and overall channel margin before committing to hardware revisions. Continuous broadband measurements eliminate the need to stitch together multiple frequency bands, reducing calibration complexity while providing a complete electrical representation of the channel from low frequencies through sub-terahertz operation. This enables consistent correlation between measured hardware performance and system-level simulations for next-generation AI networking infrastructure.

Broadband AI Interconnect Solution

Characterizing AI data center interconnects requires continuous broadband measurements across the full operating frequency range without dividing the measurement into multiple calibration bands. The workflow begins with broadband calibration of the vector network analyzer and frequency extenders, followed by synchronized system control through the test set controller. Automated frequency sweeps capture high-resolution scattering parameter data for insertion loss, return loss, group delay, differential transmission performance, and impedance consistency across complete interconnect paths. Engineers can evaluate cables, connectors, packages, and co-packaged optics, then export measured data into channel simulation tools to validate equalization strategies, compare measured and simulated performance, and optimize system architectures for 448 gigabit-per-second and future 1.6 terabit-per-second interfaces. Continuous broadband coverage simplifies validation workflows, improves measurement consistency, and reduces uncertainty associated with multiple calibration bands.
