July 12, 2004 Utica, NY--NetTest announced the addition of the CMA 5400 PMD 160 module to its CMA 5000 multi-layer test platform. This module replaces the CMA 5400 PMD 80 module.
Utilizing the interferometric method as recommended by the TIA FOTP-124, this new module scans a range up to 160 psec, doubling the maximum polarization mode dispersion (PMD) value that can be measured. Standard light sources, which allow 48-dB of dynamic range cover most applications; however, an optional 65-dB light source is available to measure ultra long haul links. NetTest's patented cross-correlation technique and choice of light sources enables the company to offer high dynamic range, fast, accurate measurements and the capability to measure PMD through erbium doped fiber amplifiers (EDFAs).
A user-friendly graphical user interface includes several modes of operation that expand the functionality, as well as make it easier for operators to perform PMD tests and qualify a network. This expanded functionality includes a histogram mode that tests the evolution of PMD with time and a multiple scan mode that guides the operator through the required steps to measure multiple scans over multiple fibers. A powerful reporting feature can display graphs and statistical information, as well as simple pass or fail test responses either on the unit's display, on paper or as PDF files.
"This latest addition to NetTest's CMA 5000 product line reinforces the company's commitment to bringing its customers the best solutions possible to characterize their networks," said Lars Pedersen, vice president and general manager, NetTest.
