LEA-041 Fiber identifier and VFL emitter

LEA-041 detect the optical signal from the fiber cable without disconnecting the fiber nor disrupting services 

pince de détection de  signal optique LEA-041

LEA-041 detects the optical signal through the coated fiber to deliver several results

  • optical signal detection with the transmission direction
  • optical power 
  • detection of the 270 Hz, 330Hz, 1 or 2 kHz modulation to identify a fiber

LEA-041 is also a 650nm red light VLF emitter for optical default diagnostics.

LEA-041 is a robust handheld equipment with long battery life that brings significant time-savings on field operation.



LEA-041 is a unique solution to perform extremely fast diagnostics and optical power measurements on live fiber without service disruption.
