Optical Fiber Multimeter- Optical Explorer OX1 Pro

The first Optical Fiber Multimeter (OFM): Link verification with embedded fault tracking


  • Displays fibre length, loss and optical return loss (ORL) in under 3 seconds
  •  On-the-spot detection of common causes of failures using EXFO’s patented Fault Xplorer™
  •  No settings required — essential multimeter for any frontline engineer
  •  Built-in power checker and light source
  •  A Go/No-Go tester for day-to-day installation and repair work


Keeping up with the accelerating pace of fiber deployments implies a major transformation in the way testing is approached. Optical Xplorer™ has been designed from the ground up to tackle the challenges ahead and simplify testing. Optical Xplorer allows streamlined procedures that reduce delays and escalation costs on the field while freeing up expert technicians to focus on more relevant tasks.

Optical Xplorer is the industry’s first optical fiber multimeter (OFM), a new purpose-built category of tools empowering frontline techs to effectively carry out installation, activation and repair operations. Optical Xplorer speeds up link health verification with embedded fault tracking — all in one single-ended test that’s quick and easy.

To cope with the increasing volume of fiber being rolled out, Optical Xplorer has been designed from the start to equip large crews of frontline technicians:

› Optimised for utmost user experience. It is highly intuitive and easy to use for any technician regardless of experience in fiber optics or other technologies (such as copper or DSL)

› Designed to reduce total cost of ownership (TCO) throughout the product life cycle by cutting all hidden costs.


Optical Xplorer goes beyond basic testing as compared to power meters and fault locators. It offers a brand new testing approach powered by multiple pending patents.

Optical Xplorer determines overall link quality and tracks potential faults, this in turn helps to boost work efficiency and quality for frontline techs. Unlike traditional instruments in their toolbox, Optical Xplorer won’t leave field technicians blind to faults. Instead,Optical Xplorer introduces new capabilities that break boundaries to redefine the role of field technicians. Each technician gets more autonomy to solve issues, enabling a leaner troubleshooting process that doesn’t require several technicians with various skills. Optical Xplorer allows a fundamental shift in work organisation—a new and better way to keep pace with the high volume of deployments and maintenance activities ahead.


While displaying insertion loss (IL), optical return loss (ORL) as well as fiber length under a few seconds and in one single-ended process, Optical Xplorer also looks for potential faults. It won’t waste precious time on good links, but if a fault is suspected, Optical Xplorer will automatically explore further and diagnose the fault, if applicable.EXFO’s patented Fault Xplorer™ technology requires no additional steps or expertise to identify and locate common causes of failure (fibre breaks, macro-bends, bad splices or faulty connectors), allowing technicians to fix problems on-the-go. Putting this new device in the hands of all technicians means faster installation and activation plus quicker mean time to repair (MTTR)—both with increased quality. Fully leverage the presence of fiber professionals on the field, while eliminating the cost and delays associated with dispatching experts and truck rolls. Once a link is verified with Optical Xplorer, a frontline technician can leave a site assured that everything concerning optical links is ready for seamless acceptance,activation or service recovery. Combined with power checking and light source capabilities in a rugged and compact form factor, Optical Xplorer is an intuitive field companion that up-skills any field technician.
