Introduction

Optical cable identifier instrument, is based on the principle of optical fiber interference, through optical coherent demodulation to convert the tapping vibration signal of the optical cable into visual and audio signals, so as to accurately find and identify targets in various laying methods Optical cable. The fiber optic cable survey instrument can be used not only for the maintenance and inspection of dedicated network fiber optic cable lines for telecom operators, electric power communications, radio and television, coal mines, and troops, but also for life rescue under passive conditions, such as underground rescue systems for mine disasters.

Optical cable search and identification are key steps in the preparatory work for the construction, installation and maintenance of optical cable lines. Therefore, the optical cable survey instrument is widely used in the construction, cutover, maintenance and resource survey of optical cable lines. When using the fiber optic cable survey instrument, engineers only need to connect the meter at the office end and tap the fiber optic cable at the remote end. The meter can convert the tapping information into audio and video signals, and can easily identify the target fiber optic cable they need to find.

Working Principle
The optical cable identifier uses the method of Mach-Zehnder optical interference to convert the percussion vibration signal of the optical cable into a visual signal and audio signal through optical coherent demodulation, so as to accurately find and identify laying in manholes, tunnels, pipelines and Target optical cable in environments such as overhead poles.
