Fiber optic connector active link connection loss caused mainly by the following aspects:
1.Fiber core
2.Horizontal mismatch
3.Vertical mismatch
4.Axial mismatch
The most important factor caused Insertion Loss (IL) is horizontal mismatch.
Figure1 High horizontal mismatch, high IL
The first task to reduce horizontal mismatch is to reduce the Insert loss of optical fiber connector.
Two way can well control Horizontal mismatch:
1.The concentricity of fiber core well control;
2. Make fiber core concentricity with not very ideal optical fiber connector’s eccentricity be adjusted to a fixed region.
Experiment with 10 connectors, before tune, IL=4.8dB
Each fiber optic connector after tune, IL=0.8dB
Core Tuner was developed by Dimension Technology based on many years of experience in instrument development and the fiber optic connector concentricity testing adjusting equipment.
Superior image processing capabilities gives Core Tuner excellent performance—high numerical accuracy, repeatability and automation, intelligent, easy to use, strong vibration resistant, and durable!
Dimension Technology developed two kinds of equipment—automatic Core Manual Core Tuner C and Auto Core Tuner S to meet different requirements from customers.. Either manually or automatically adjustable core are defined new standards for instrument.
