QUEBEC CITY, March 24, 2011 — Exfo Inc. has added several tools to its PSO-200 optical modulation analyzer software, providing flexibility to manufacturers looking to adapt their testing protocols to future compliance procedures and allowing performance of phase-modulated transmitters such as dual-polarization quadrature phase-shift keying (DP-QPSK) to be established independently of the receiver.

Added are detailed error vector magnitude (EVM) and bit error rate (BER) analysis, mask tests and support of homodyne characterization. The software release provides network equipment and transceiver manufacturers with tools for testing and troubleshooting during production of 40- and 100-Gb/s transmitters.

With 40- and 100-Gb/s DP-QPSK transmitters now commercially available, manufacturers face challenges when transferring the products from R&D to production, among which are the absence of compliance criteria and standardized procedures against which to test. The company developed the time-resolved EVM analysis to enable fast and precise identification of transmitter impairments.

The optical modulation analyzer also provides BER and symbol error rate computation in a gearbox that allows users to provide the patterns and sequences used in their transmitter to obtain precise mapping of errors, ITU-T and IEEE-based compliance mask tests for on/off keying modulation formats, as well as constellation and time-resolved EVM masks for phase-modulated signals.

The analyzer offers optional external local oscillator input to support the requirements for homodyne characterization, useful when testing transmitters using lasers with larger linewidths, such as 40-Gb/s DP-QPSK modules with coherent instruments.
