EXFO announces encouraging data from PSO-200 optical modulation analyzer study

Sep 21, 2011 (Datamonitor via COMTEX) -- EXFO Inc., a provider of test and service assurance solutions, has announced that its PSO-200 Optical Modulation Analyzer has simultaneously measured the bit error rate, or BER, of a DP-NRZ-16-QAM signal beyond the industry-required forward error correction, or FEC, limit and demonstrated waveform measurements using industry-standard word length, all at an astounding 66 GBd rate.

The result of this demonstration marks an industry first on such high-speed 16-QAM signals. Furthermore, it shows that the PSO-200 not only offers the most efficient solution for characterization of 100 Gbit/s signals, but is also the flexible approach for characterization of signals beyond 100 Gbits/swhere both multilevel QAM and higher symbol rates will likely be used, the company said.

EXFO's PSO-200 Optical Modulation Analyzer is the instrument capable of providing distortion-free characterization of phase-modulated signals for transmission rates up to 100 GBd. In addition to supporting the OIF (Optical Internetworking Forum)-recommended DP-QPSK for 100 Gbit/s transmission, the PSO-200 supports modulation schemes and baud rates that could allow transmission of signals at over 1 Tbit/s.

"EXFO has been at the forefront of 100G testing by offering several 100G-focused transport and optical test solutions as early as 2009. The performance demonstrated here shows that EXFO is always looking ahead to offer innovative and future-proof solutions to its customers," said Etienne Gagnon, EXFO's Vice-President, Wireline Division and Corporate Marketing. "The PSO-200 Optical Modulation Analyzer, now more than ever, addresses the needs of system developers working on next-generation networking technologies by supporting today's and tomorrow's ever-increasing demand for bandwidth."
