All-Optical Sampling—No Boundaries With the new advanced modulation schemes that enable transmission of high-speed optical signals over fiber, research centers, network equipment manufacturers (NEMs)—and eventually carriers—need new test instruments to properly characterize these signals. Like EXFO’s recognized PSO-100 Series Optical Sampling Oscilloscopes, the PSO-200 Optical Modulation Analyzer uses optical sampling, allowing complete characterization of random or repetitive digital signals up to 100 Gbit/s. Distortion-Free Signal Recovery One of the crucial elements to take into account when characterizing or optimizing transmitters and modulators is the recovery of perfect signals and waveforms. A distortion-free signal recovery is precisely what the optical sampling technique used in the PSO-200 brings when compared to electrical sampling. With the PSO-200, there are no bandwidth limitations—no impedance mismatch. With high bandwidth and low distortions the PSO-200 is able to measure constellation diagrams with very high fidelity without the need for equalization or DSP enhancement.
