Key features

  • All-optical design providing the effective bandwidth to properly characterize waveforms and signals at 40 Gbit/s, 100 Gbit/s, 400 Gbit/s, 1 Tbit/s and beyond
  • Compatible with dual-polarization transmission
  • Fully integrated with the smallest form factor in the industry
  • Includes all the required tools for testing of transmitters in manufacturing such as EVM, BER and masks
  • Large touchscreen for high graphic quality and easy instrument control


  • Manufacturing testing of phase-modulated transmitters like 100G DP-QPSK
  • Design and optimization of system band on phase and amplitude modulation schemes at rates up to 1 Tbit/s and beyond

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.
