Fiber Optic Amplifier and Sensing Patch Cord
How to Combine a General-Purpose Fiber Optic Amplifier with a Plastic Fiber Optic Sensing Patch Cord
I. Selection and Matching Key Points
Compatibility Screening: Prioritize general-purpose fiber optic amplifiers that support plastic fiber optic interfaces, matching the core diameter and numerical aperture parameters of the patch cord to avoid excessively low optical coupling efficiency.
Light Source Compatibility: Use a red 4-element LED (wavelength 635nm) to match the low attenuation characteristics of plastic fiber optics, ensuring effective long-distance signal transmission.
II. Practical Integration Steps
Optical Path Connection: Connect both ends of the plastic fiber optic sensing patch cord to the amplifier's optical transmitter and receiver ports respectively, ensuring the end faces are clean and free of scratches.
Structural Fixing: If the patch cord has a built-in coupling point, attach a dedicated detector to the patch cord's reinforcement section and rotate to lock it in place to complete optical path coupling.
Parameter Adjustment: Set the threshold in the amplifier's operating interface, calibrate the incident light amount, and complete the signal stability test.
III. Typical Application Scenarios
Industrial Inspection Scenarios: Used in conjunction with through-beam/reflective detection modes for workpiece counting and small object positioning detection in confined spaces.
Online monitoring scenario: Relying on its anti-electromagnetic interference characteristics, it enables long-distance distributed sensor signal amplification and transmission in power and rail transit scenarios.
