JDSU Unveils Fiber Dispersion Analyzer

JDSU introduced an Optical Dispersion Measurement (ODM) module for its T-BERD/MTS-6000 and T-BERD/MTS-8000. The module provides chromatic dispersion (CD), polarization mode dispersion (PMD) and Attenuation Profile test functions. These tests can help validate the fiber link's compatibility with high-speed CWDM/DWDM systems, including Reconfigurable Optical Add/Drop Multiplexers (ROADMs). The performance of each individual function also makes the ODM module ideal for characterizing fiber at 40G and higher.

JDSU said measuring CD, PMD and attenuation is essential during fiber characterization, a series of tests performed to identify fiber viability for very high-speed transmission systems (10 GigE, 40G and higher) in both the installation and maintenance phases. If not properly managed, CD, PMD and attenuation cause severe performance effects on transmission quality that must operate at peak performance in order to deliver reliable broadband services.
