1 Introducing the PSO-200
Optical Modulation Analyzer
As new advanced modulation schemes enable the transmission of
high-speed optical signals over fiber, research centers, network equipment
manufacturers and eventually carriers need new test instruments to
properly characterize these signals.
Main Features
The PSO-200 Optical Modulation Analyzer uses equivalent-time optical
sampling, allowing the complete characterization of random or repetitive
digital signals at 100 Gb/s, 400 Gb/s, 1 Tb/s and beyond.
The PSO-200 displays constellation charts, eye diagrams and patterns with
very high temporal resolution. It is a useful tool to study and characterize
very high bit-rate systems or very fast events like short pulses, where the
bandwidth of ordinary electrical sampling oscilloscopes is not sufficient.
The PSO-200 can measure a number of modulation formats: OOK, BPSK,
APSK, QPSK and 16-QAM, all in return-to-zero (RZ) or non-return-to-zero
(NRZ) formats.
