Simplifying Resistive Fault Location
With G.fast opening up a new path for ultra-broadband services, the copper pair is still an evolving force to be reckoned with. Deploying new technologies over copper requires the ability to reliably test and quickly troubleshoot these services.
High resistive faults on voice and broadband cable pairs are usually caused by damage or deterioration of the cable insulation protecting the copper pair wires. In most cases, the culprit is water, moisture or corrosion. This is where resistive fault location (RFL) comes in handy. RFL is a powerful measurement technique used to locate the faults quickly and easily.
There are several variants of RFL that can be used depending on how bad things are. Understanding them will help you fix faults quickly and more effectively.
Learn more about these RFL variants and test measurements by reading EXFO’s Simplifying Resistive Fault Location.
