This video explores the OTDR general user interface housed in the FTB-400 platform.

With a global market share of more than 50%, EXFO has been a proven OTDR expert for over 25 years. With models optimized for all types of optical networks—FTTH, access, metro, long-haul, ultra-long-haul—you will find in this brochure the right OTDR solution for your requirements.

This article explains the differences between an OLTS and an OTDR, namely the specific applications of each tool and how loss measurements are obtained with each.

This article presents how the optical time domain reflectometer (OTDR) remains the only instrument available to characterize fibers at the required level of detail.

This article discusses EXFO's implementation of the Bellcore OTDR format, which offers the advantage of being able to build a database with test results from different OTDR manufacturers.

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

This application note reviews the critical parameters (and the order in which they should be tested) and the general criteria for quality transmission.

This application note presents EXFO's instruments for in-service PON troubleshooting.

This application note goes through the step-by-step situation assessment and troubleshooting procedure that allows network operators to repair the break in a specific FDH splitter branch, while maintaining service on the other branches.

This application note presents the key specifications that should be considered when purchasing an OTDR.

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 application note explores the fundamental OTDR principles that are key to understanding the specifications of this instrument.

This application note compares a traditional and complex test method that uses transmission wavelengths to an innovative and simple test solution that uses a filtered out-of-band wavelength.

This application note explores the challenges and benefits of a PON-optimized OTDR.

This application note examines the repercussions of bandwidth expansion projects in all the segments of a CATV network.

This technical note demonstrates why a small elevation sometimes appears on the graph after a strong reflective event when using some OTDR modules.

This technical note provides some experimental results and a few design rules to adequately address the Raman scattering problem.

Leading the OTDR market with a 48% market share and the broadest OTDR portfolio, EXFO offers an OTDR built smart for any type of network. Based on true understanding of the field reality and 20 years of OTDR expertise, EXFO’s OTDRs are designed to meet network operators’ latest requirements. Learn how our OTDRs can provide you with measurements you can trust, while minimizing truck rolls and accelerating workflow in the field.

This course covers advanced OTDR analysis functions and the post-processing tools related to OTDR testing. Attendees will learn how to use the time-saving features of EXFO’s OTDRs; namely, ToolBox, iOLM features and FastReporter software.

This course provides a complete training of FTTH PON and how to test a network at every steps of its architecture. Using the complete FTTH testing products, all test phases will be covered: construction, activation and troubleshooting.

This course offers an overview of FTTH PON and how to test a network at every steps of its architecture. Using the complete FTTH testing products, all test phases will be covered: construction, activation and troubleshooting.

This course teaches attendees how to interpret OTDR measurements based on general reflectometry theory. The course also discusses the limitations of both the theory and the instrument, as understanding these limitations will enable the attendees to get reliable results from an OTDR.
