SmartClass Fiber MPOLx – MPO Optical Loss Test Sets

First Dedicated Tier 1 (Basic) MPO Certification Solution

The VIAVI Solutions SmartClass Fiber MPOLx is the industry’s first dedicated optical loss test set that can perform all the test requirements for Tier 1 (Basic) certification using MPO fiber connectivity.

SmartClass Fiber MPOLx – MPO Optical Loss Test Sets

The MPOLx provides a source and power meter that integrate essential test capabilities together to ensure a fast and reliable workflow when testing and certifying network links with native MPO connectivity.

With the MPOLx, field technicians can perform all the necessary test requirements for Tier 1 (Basic) certification in a single solution:

  • Measure MPO length
  • Measure optical loss
  • Check polarity
  • Inspect fiber end faces
  • Generate certification reports


The MPOLx gives technicians the ability to achieve a completely new level of productivity for testing and certification. Like all our solutions for Tier 1 (Basic) fiber certification, identical local and remote units are provided to enable full visibility and control by performing tests from both the Light Source and Power Meter. All devices feature a 3.5” color touch screen and integrated inspection for both bulkhead and trunk connectors. The MPOLx allows a single technician to inspect MPO end faces and perform tests from either end of the connection, reducing walking back and forth between the two units.

The MPOLx ensures fast workflows by delivering comprehensive test results in less than 6 seconds for all 12 fibers of the connector providing color coded pass/fail test results, test limit, fiber length, test wavelengths, loss values, margins, and polarity results for each fiber.
