This article presents the intelligent Optical Link Mapper (iOLM), an automated technology that uses advanced algorithms ensuring that all elements of a link are fully and accurately characterized.

This article gives a typical example of a Microsoft Visual Basic program, designed to control EXFO’s tunable laser source and PDL meter to measure a component’s PDL as a function of wavelength.

This article reviews the critical parameters of TLS applicable to EDFA and system testing; it also examines the performance characteristics of a tunable DFB laser source.

This article explains how an OTDR with an APC connector will require less frequent repairs (connector change) to deliver constant measurements and reliable testing.

The ARU-100 helps evaluate HPNA networks for impairments and their ability to support triple-play services delivered by FTTx networks.

This technical note provides an overview of EXFO's fully qualified and automated in-house power meter calibration system (EPMCS).

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

This articles explains the importance of PMD in high-speed digital and analog networks; it has to be measured not only after manufacturing but also after cabling and installation.

This article provides an overview of polarization,a common factor in a number of phenomena that must be characterized if high-bandwidth systems are to attain their full potential.
