Our VIAVI portfolio is focused on practical tools for installation, verification and troubleshooting of fiber optic networks.
VIAVI products and solutions
OTDR testing
An Optical Time Domain Reflectometer (OTDR) is used to test, document and troubleshoot fiber optic links. It provides information about events along the fiber, including connectors, splices, reflections, attenuation and breaks.
Foss offers selected VIAVI OTDR solutions for both single-mode and multimode networks.
Our range includes SmartOTDR instruments for portable field testing as well as the modular MTS-4000 platform for more advanced measurement requirements.
Different configurations are available depending on wavelength, dynamic range, fiber type and application.
Fiber inspection
Contamination and damage to fiber connector end faces can cause insertion loss, reflections and unstable connections. Inspection should therefore be an important part of fiber installation and maintenance.
Foss offers VIAVI digital fiber inspection microscopes including P5000i and FiberChek Probe.
The inspection systems can provide automated analysis of fiber connector end faces and pass/fail evaluation, helping technicians achieve consistent and documented inspection results.
A range of inspection tips is available for different connector types and applications.
Optical power and loss testing
Optical power meters, light sources and test kits are used to verify optical power levels and measure insertion loss in fiber optic links.
Our VIAVI range includes SmartPocket power meters and test kits for both single-mode and multimode applications.
Available solutions include individual power meters and light sources as well as complete test kits for common telecom and enterprise wavelengths.
Visual fault location
For quick identification of faults in fiber optic links, a Visual Fault Locator (VFL) can be used to inject visible light into the fiber.
A VFL can help locate fiber breaks, severe bends and other faults over shorter distances and is a useful tool for installation and troubleshooting.
Foss offers compact VIAVI visual fault locators as part of our fiber optic measurement portfolio.
More than test equipment
Reliable fiber measurements depend on more than the instrument itself. The correct measurement method, settings, reference conditions and accessories are all important for obtaining useful results.
With extensive experience in fiber optic infrastructure and testing, Foss can help you select equipment that matches the network and the measurements you need to perform.
Whether you need a compact instrument for everyday field work or a more advanced OTDR configuration, we can help you identify the appropriate solution from our VIAVI range.
