This article simplifies polarization mode dispersion, using specific examples and formulas.

This note examines how each application can be tailored to address individual requirements, so as to help service providers select the best approach for them.

This application note demonstrates how linearity at the far end of an OTDR trace is very important to guarantee proper link loss, event loss and attenuation readings.

This article demonstrates how OSNR can be derived, for each individual channel, from an optical spectrum measurement to obtain indirect information about the performance of these channels and hence of...

This article presents the phase-shift method, a more commonly used and standardized technique to determine the chromatic dispersion is referred to and in which light is sinusoidal-intensity modulated.

This article describes methods to optimize OTDR measurement parameters by presenting processes and key parameters.

This application note demonstrates how the test features of the Packet Blazer SAN FTB-8520 can qualify and optimize an end-to- end Fibre Channel network as a whole, at all levels, including the interc...
