This application note explains why it is important for MSOs using multiwavelength transmission in the O band over standard singlemode fiber to understand the four-wave mixing phenomena.

This application note discusses two of the main aspects of fiber certification; namely, industry standards and light source launch conditions.

This application note examines a case in point in which the CENX and EXFO partnership has created an end-to-end, service-assurance solution that provides visibility to the end user over multiple netwo...

This article explains how service providers can make certain that all new 40G/100G circuits in service are proven capable of handling any of the demanding services thanks to EXFO’s FTB-85100G Ethernet...

This article offers insight into troubleshooting Ethernet services with the implementation of EXFO’s new packet-capture and decoding capabilities.

This article explains how users can acquire information about the transmitted signal that would not have been able to obtain, such as the probability of error of each individual bits/bytes in a patter...

This application note explores ODU0/ODUflex as their implementations in the OTN technology are key enhancements in the transport network.

The key to successfully commissioning a Raman optical amplifier with low PDG is to pump the non-linear optical fiber media with sources thatare almost completely depolarized. This can be achieved by c...

This articles discusses how to maximize network availability and efficiency, and improve customer QoS through centralized, integrated network performance and service-management processes.

This article discusses the need to measure PMD values to the femtosecond range and how to achieve this by performing complete analysis of polarization states.
