The EXFO PSO-100 Series Optical Sampling Oscilloscopes are all-optical instruments engineered for high-speed signal integrity measurements, waveform characterization, and jitter analysis in 40G/100G and optical networks. These single-channel (PSO-101) and dual-channel (PSO-102) models eliminate the constraints of traditional electrical sampling by employing an all-optical gate architecture with narrow sampling pulses that generate time-stretched signal replicas. The result: bit-rate and modulation-scheme independence with transmission rate capability to 640 Gbit/s.
Technical Specifications
