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.

In the last 12 months, we have seen multiple trials for 200G and 400G transmission worldwide on both client and line sides, which have presented multiple challenges. At this moment, new technologies and standards are being developed by groups, such as ITU, IEC, OIF, IEEE, to meet beyond 100G network requirements.  This webinar will review the potential technologies enabling transmission beyond 100G and the expected challenges related to deployment and testing, with a particular focus on long-haul and metro requirements.
