LEA-422 provide fast and high accuracy measurements of single-mode fiber issues over dozens of km.

It defines the exact location and nature of fiber events such as connectors, splices, stress, etc. to enable efficient diagnostics and maintenance operations.

It embeds smart software algorithms that perform event analysis to determine the nature of the events.

LEA-422 is a very versatile, compact, cost-effective product that provide fast and easy operation:

  • OTDR : fiber default location, measurement, analysis
  • High-accuracy optical power meter : -70 to +10 dBm input range
  • Optical source : 1310 and 1550 nm wave length
  • 650nm red light VFL emitter for visual fault diagnostics 
  • Ethernet cable tester : continuity, impairement and length measurement, cable detection from a modulation signal detection


LEA-422 OTDR is a key test and measurement equipment when complex defaults appear on the fiber link or when accurate fiber qualification is required.

It provides a graphical interface with detailed results for measurements over dozens of km that suits most industry networks and GPON/FFTH/FTTO service providers.
