Applying service assurance early in a VoIP rollout ensures the service is ready at the same time as the network. Operators will be trained. Metrics will be relevant. Critical parameters will be captur...

This article reports and analyzes states of polarization (SOP) and polarization mode dispersion (PMD) measurements on aerial fiber under moderate to severe wind conditions.

This article presents how to measure polarization dependence of DWDM passive devices with the IQS-12004B DWDM Passive Component Test System.

This article presents the results of ORL testing of 16-channel thin-film multiplexer/demultiplexer using EXFO's IQS-12004B DWDM Passive Component Test System.

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

This article shows the importance to perform reliability testing in order to determine the long-term behavior of passive components.

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.
