The evolution of telecommunication services and applications has
led to an amazing increase in the demand for network capacity.
Wavelength division multiplexing (WDM) technology is a flexible
way to improve a link's bandwidth, or information-carrying
capacity, because it uses several carriers on the same fiber, each
having its own wavelength.
The introduction of dense WDM (dense refers to the use of several
channels in the 1550 nm spectral window) in the field has brought
tighter optical design criteria and the new "spectral" dimension,
resulting in a call for new testing parameters. The implementation
of dense WDM systems forces operators to consider a new dimension:
wavelength. Consequently, the optical spectrum analyzer
became a must for dense WDM network operators.
For more than ten years, EXFO has always been at the forefront of
the testing instrumentation industry. By understanding our customers'
present and future needs, we have managed once again to
deliver reli
