QUEBEC CITY -- EXFO Electro-Optical Engineering Inc. (NASDAQ: EXFO, TSX: EXF) announced today the introduction of the WA-5900 WavemeterÒ Fiber Bragg Grating Monitor. The new WA-5900 leverages EXFO’s best-in-class test and measurement expertise to allow monitoring of environmental conditions such as temperature, pressure and strain in remote areas using fiber-optic sensors. In applications involving petrochemical, civil, geophysical and utilities, the data from the WA-5900 enhances industrial productivity and provides early warning for hazardous situations. Fiber-optic sensors offer distinct advantages for remote monitoring because they are environmentally stable, offer higher accuracy measurements and have a longer lifetime. In particular, the fiber Bragg grating (FBG) based fiber-optic sensor is preferred, especially for the most demanding applications. Significant benefits include:

The new WA-5900 Wavemeter Fiber Bragg Grating Monitor employs EXFO’s proven scanning Michelson interferometer-based technology to measure the absolute wavelength of the optical signal reflected from FBG-based sensors. In addition, all factors that can affect the absolute wavelength measurement are accounted for in order to achieve the highest absolute wavelength accuracy.“With fiber-optic sensors, the information of interest is encoded with the absolute wavelength of the optical signal reflected from the FBG. As a result, it’s critical that the absolute wavelength of the reflected optical signal is measured precisely, a particular strength for EXFO,” said Germain Lamonde, Chairman, President and CEO of EXFO. “The new WA-5900 continues our tradition of offering the highest standard in wavelength measurement accuracy-a key requirement in fiber-optic sensing applications. The WA-5900 measures the absolute wavelength to a guaranteed accuracy of ± 1.5 pm.”EXFO Electro-Optical Engineering Inc.
