The transition to 200G/Lane transmission presents fundamental measurement challenges. Traditional test equipment lacks sufficient bandwidth to capture harmonic content and high-frequency distortions, which become increasingly critical at 100 Gbaud PAM4 signaling rates. This bandwidth limitation hinders the accurate measurement of key optical parameters required by industry standards, potentially causing important characteristics to be missed during development and manufacturing validation.
The shift in aggregate data speeds from 800G to 1.6T exacerbates this challenge, as multiple high-speed lanes must be evaluated simultaneously without compromising measurement accuracy or performance requirements. The technology will be showcased at Anritsu's booth C4335 at ECOC 2025 (Copenhagen, September 29–October 1), where real-world applications will be demonstrated in the validation of 1.6T transceivers and in AI data center infrastructure testing.
Product Features
Engineering Solution: 60 GHz Sampling Architecture
The MP2110A-080 employs a 60 GHz sampling front-end specifically designed to capture the essential spectral components for accurate PAM4 TDECQ (Transmitter Dispersion Eye Closure Quaternary) measurements at 200G/Lane speeds. This bandwidth expansion allows engineers to:
Characterize high-frequency signal degradation mechanisms that were previously invisible to lower-bandwidth instruments.
Validate compliance with the new 200G/Lane standards that require accurate eye-closure penalty measurements.
Identify intersymbol interference patterns that only manifest in the extended frequency domain.
Key technical specifications:
60 GHz optical sampling bandwidth: supports PAM4 signals up to 120 Gbaud
Simultaneous 4-channel measurement: enables characterization of multi-lane transceivers
4x faster sampling rate: reduces measurement latency for high-throughput manufacturing
Integrated reference receiver performance: maintains TDECQ measurement accuracy across the entire expanded bandwidth
Software-upgradeable number of channels: provides a scalable deployment path from 2 to 4 channels.
