The Multif project made it possible to develop an essential testing bed for developing multi-frequency optical communications technology. The innovative aspect of this project was that it perfected a device capable of generating specific optical frequencies, of which the communications channel frequencies meet the highest established standards. The Centre at Université Laval for Optics, Photonics, and Laser technology was thus able to generate an absolute frequency scale of 100 GHz. The testing bed was completed last summer, and is bound to be an invaluable scientific tool for assessing future telecommunications technology.
