SmartClass Fiber MPOLx
The MPOLx integrates a light source and a power meter into a single device, while combining all essential testing capabilities to ensure that testing and certification of MPO-based network links are fast, efficient, and reliable.
With MPOLx, field technicians can perform all required tests for Tier 1 (Basic) certification within a single solution, including:
- Measuring MPO cable length
- Measuring optical loss
- Checking polarity
- Inspecting fiber end-faces
- Generating certification test reports
The MPOLx promotes proper testing best practices by consolidating all critical functions into one device, reducing workflow complexity and enabling technicians to work faster through improved testing workflow efficiency.
Highlights
The MPOLx enables technicians to achieve unprecedented levels of efficiency in testing and certification workflows.
Like all VIAVI Tier 1 (Basic) fiber certification solutions, every MPOLx unit includes identical Light Source and Power Meter functionality, allowing users to fully view and control test data from both ends of the link.
Each device is equipped with:
- A 3.5-inch color touchscreen display
- Built-in connector inspection capability
- Support for both bulkhead and trunk connector inspection
The MPOLx enables a single technician to inspect MPO connector end-faces and perform testing from both ends of the connection, eliminating the need to move between two separate devices and significantly saving operational time.
In addition, the MPOLx accelerates the testing process by delivering complete results for all 12 fibers of an MPO connector in under 6 seconds, while providing comprehensive key data, including:
- Pass/Fail results with color-coded indicators
- Test limit references
- Fiber length measurements
- Test wavelengths
- Loss values
- Margin values
- Polarity results for each individual fiber
All of this ensures that MPO system testing and certification is performed quickly, accurately, and with maximum efficiency.
