Turnkey optical modulation analyzer


EXFO Electro-Optical Engineering Inc. has announced the release of the PSO-200 Optical Modulation Analyzer that enables complete characterization of amplitude- or phase-modulated signals at speed up to 100 Gbaud, specifically designed for R&D labs and manufacturing environments.

Thanks to its flexible design, the PSO-200 is a future-proof tool that enables the characterization of any optical signal with minimal distortion. Its effective bandwidth is broad enough to allow constellation and eye-diagram analysis of signals with baud rates up to 100 Gbaud, which means that signals could be analyzed at up to 400 Gbit/s when using a four-symbol modulation format such as DP-QPSK. Detailed and accurate amplitude and phase patterns can also be obtained to offer powerful pulse-shape analysis for transmitter optimization and troubleshooting.

Very high-speed transmission over networks is enabled through efficient modulation of signals, whether it is phase, amplitude or both. To design 100G systems based on such advanced modulation schemes and to make sure they are ready for deployment, network equipment manufacturers (NEMs) have so far worked with in-house test solutions, which are often complex or limited. The introduction of the PSO-200 Optical Modulation Analyzer means engineers working in R&D labs and manufacturing environments now have access to a turnkey and comprehensive test instrument that makes bandwidth limitation irrelevant.
