PMD of the new optical cable
Polarization Mode Dispersion (PMD) is a limiting parameter of high bit rate optical transmission system. Testing PMD is essential in order to characterize the fiber's suitability to support high speed transmission such as 10 Gb/s, 40 Gb/s or even 100 Gb/s. With the advent of new advanced modulation formats being used to transport 40 Gbit/s and 100 Gbit/s transmission rates, a number of publications on polarization mode dispersion (PMD) and differential group delay (DGD) specifi cations have been produced in the industry. As data rates continue to soar, understanding and mitigating PMD becomes increasingly important. The 2820 Interferometric PMD System is the optimal PMD test solution for optical fiber and cable production.
