Evaluating 400 GbE and 56G × 4 Lane Systems
By using a MUX/DEMUX supporting bit rates up to 56 Gbit/s, it is possible to evaluate 400 GbE EML and optical modules using 4ch synchronous operation now being investigated by IEEE 802.3 bs.
Confirming Skew and Crosstalk Effects
Applications using 56-Gbit/s class signals require both theoretical and practical verifications. Since the MP1800A supports pattern synchronization and has a phase tuning function, it is the ideal instrument for easy examination of Rx device skew tolerance, crosstalk effects, etc.
Ideal Signal Quality for EML Evaluations
With a tunable output function of up to 3.5 Vp-p, EMLs can be driven directly. The amplitude and crosspoint can be adjusted easily on the screen to shorten evaluation times and offer high-reliability evaluations.
Built-in High-Sensitivity Auto-Search Function
The built-in DEMUX MP1862A Auto Search function supports auto-tuning of the Data and Clock phase difference as well as optimization of the voltage threshold value. It is possible to easy operation for optical receiver sensitivity tests.
