Distortion-Free Characterization of Signals at 40 Gbit/s, 100 Gbit/s and Beyond
The PSO-100 Series has a 500 GHz bandwidth allowing accurate measurement of rise/fall time, jitter, duty cycle distortion, mask hits, etc.—even with more complex modulation schemes such as CSRZ-DPSK.
No Need for an External Clock
The unique software-based clock recovery technique of the PSO-100 Series enables trigger-free and easy-to-use waveform visualization and analysis. If the optical signal-to-noise ratio (OSNR) of the input signal is greater than 20 dB, you simply have to enter the transmission bit rate (within ±8 MHz) for optimal synchronization without requiring an external clock.
An optional external clock input is available should you have to synchronize on noisy signals or low duty cycle return-to-zero (RZ) signals, get accurate clock jitter measurement, or enable time-stamping of optical samples. Any sub-rate of the input signal can be used as the synchronization clock.
Bit-Rate and Modulation-Scheme Independent
The unique design of EXFO’s optical sampling oscilloscopes ensures a universal future-proof solution. Since the PSO-100 Series is an all-optical instrument, no bit-rate-dependent hardware is needed. The same oscilloscope can be used for any bit rate, up to 640 Gbit/s: just select the single-channel or the dual-channel version based on modulation schemes needed. Furthermore, both channels of the PSO-102 can be used independently or in differential mode for DPSK, DQPSK and D8PSK.
All Complex Applications Covered
DxPSK Measurements
To perform DPSK, DQPSK or D8PSK characterization, simply add a demodulator to your PSO-102.
Ultra-Long-Haul and Submarine Circulating Loops
The PSO-100 Series also offers an optional Gated mode, which eliminates the need to manage long and expensive fiber spools to simulate links that can be thousands of kilometers long. You just have to use a short fiber spool and configure your test setup as shown below to perform accurate measurements after the required number of loops to match the simulated link.
