CHROMATIC DISPERSION APPLICATION

CMA5000 CD-Phase

Most Versatile and Accurate System Available for CD Measurements

The field portable CMA5000 Chromatic Dispersion measurementsystem is a dedicated module that combined with the CMA5000 mainframe will provide installers, network providers and network de- signers an advanced Chromatic Dispersion measurement instrument. The CMA5000 Chromatic Dispersion measurement system is based upon the industry accepted phase shift method that can evaluate chromatic dispersion of individual fiber links or entire networks con- sisting of multiple EDFAs. Utilizing a single fiber for the test, as well as a tunable laser, results in a reduction in the testing time and an in- crease in the accuracy of the measurement. This translates into im- proved network performance and efficiency, resulting in increasing revenue for the network provider. NetTest understands how valuable your time is, so we’ve provided in- tuitive, easy-to-use setup menus and single button operation. The CMA5000 Chromatic Dispersion measurement system has been de- signed to provide optimal test efficiency to facilitate quicker turn-up of services and reduce the cost of testing. The CMA5000 provides complete control over the wavelengths measured, allowing for the in- strument to be quickly configured to test only the specific wavelength areas of interest, increasing efficiency and saving valuable time. Wavelength can be selected so accurately to allow even the mea- surement of Chromatic Dispersion (CD) on an individual DWDM channel basis. With intuitive setup menus, the user is guided through a few minor settings that provide the industry’s most accurate mea- surements of all fiber types. The field portable CMA5000 is the most versatile and accurate sys- tem available for Chromatic Dispersion measurements on all single- mode fiber types. It provides installers, carriers and system providers increased revenue through optimized network bandwidth while im- proving efficiency and reducing operational expenses through proper CD mitigation and compensation techniques.
