QUEBEC CITY, May 14 -- EXFO Electro-Optical Engineering Inc. said its polarization mode dispersion and chromatic dispersion analyzers have successfully completed a test on a 5,513-km undersea optical network belonging to Hibernia Atlantic, an Irish-based transatlantic carrier. The analyzers, housed inside the company’s FTB-400 modular platform, swept through more than 120 erbium-doped fiber amplifiers along an optical network between Southport, England, and Halifax, Nova Scotia. "The results of these test trials with EXFO have proven to be conclusive," said Philip Pilgrim, submarine transmission specialist at Hibernia Atlantic. "Not only did their dispersion testing allow us to verify critical aspects of our system's optical performance prior to loading customers, but also by revealing very low PMD levels, it confirms that the system is suitable for 40 Gb/s wavelengths in the future."
