OTDR/CHROMATIC DISPERSION APPLICATION

CMA5000 CD-OTDR

Measure Chromatic Dispersion and Loss in One Step

The field portable CMA5000 OTDR/ Chromatic Dispersion (OTDR/CD)measurement system is a dedicated module that combines the ad- vanced capabilities of Anritsu’s OTDR technology with Anritsu’s ex- perience in Chromatic Dispersion. The CMA5000 OTDR/CD mea- surement system gives installers and network providers a combined module that can be used as an OTDR and a chromatic dispersion measurement system, reducing testing times while increasing net- work performance. The CMA5000 OTDR/CD measurement system is based upon the industry accepted time-of-flight measurement method (FOTP-168) that can evaluate chromatic dispersion of indi- vidual fiber links. Utilizing a single fiber for the test and multiple wave- lengths results in an increase in the accuracy of the measurement, as well as a reduction in the testing time. This translates into im- proved network performance and efficiency, resulting in increased revenue for the network provider. Anritsu understands how valuable your time is, so we’ve provided in-tuitive, easy-to-use setup menus and single-button operation. The CMA5000 OTDR/CD measurement system has been designed to provide optimal test efficiency to facilitate quicker turn-up of services and reduce the cost of testing. The combined unit has an auto-test feature that will determine the optimum settings. In addition, intuitive setup menus guide the user through a few minor settings that mini- mize the testing and setup times. The field portable CMA5000 OTDR/CD is an accurate system avail- able for measuring both Chromatic Dispersion, loss and attenuation on all single-mode fiber types providing installers, carriers and sys- tem providers increased revenue through optimized network band- width, while improving efficiency and reducing operational expenses through proper CD mitigation and compensation techniques.
