High level operation

The following automatic optimization functions based on optical fiber condition, and the automatic compensatory function in low temperature and low pressure environment.

• Before the fiber is spliced, get by image measurement the end face shape, cutting angle, fiber eccentricity and other parameters of the fiber; and modify accordingly the forward speed and amount of overlap and other splice parameters.

• “AUTO” automatic splice mode: Built-in automatic control splice modes suitable for SM, MM, DS, NZ four fibers. In “AUTO” mode splicing process, by real-time analysis on fiber “thermal image”, the machine adjust and control in real-time the arc time and correct automatically the arc intensity of next splicing, meeting the user’s demand that the splice parameters are always stable when the operation environment changes during the splice .

• “CALIBRATE” self-calibration splice mode: The built-in self-calibration splice mode is suitable for SM, MM, DS, NZ four fibers. In “CALIBRATE” mode: the fusion splicer gets and analyzes the characteristics of the fiber “thermal image” before welding. After finishing the analysis, the machine corrects automatically next splice arc intensity according to “estimate splice loss”. This splice mode is used by the factory for the configuration of different types of fiber optics.

Select splice mode according to the type of optical fibers

<1> Different fibers have different splice parameters. In the fiber splice operation, the user shall choose a suitable fiber splice mode according to the type of fibers to be welded.

<2> In “Select splice parameter files” screen, there are a total of 12 sets of different kinds of fibers.

Splicing operation

This series of fusion splicers are installed with an image processing system to observe and inspect the optical fiber. However, the image processing system may not discover fusion splicing errors in some cases. In order to achieve good welding results, the operator needs the LCD to monitor visually the entire welding process of the optical fiber. The following describes the standard welding steps.

• Inspection on cutting angle and end face of the optical fiber

Two optical fibers are loaded into the fusion splicer and are moved forward each other. After cleaning arc, two optical fibers are stopped respectively at a set position. The operator shall then check the cutting angle and the quality of the end face of each fiber. If the measured fiber cutting angle is bigger than the set limit (factory default value), or the operator checks out the end face of the optical fiber has a burr, the machine buzzer alarms. At the same time, the LCD will show an overrun alarm message. Fiber splicing process is paused automatically. To ensure the quality of welding, the user is recommended to make again a good fiber end face and place the fibers into the machine once again.

• Automatic aligning and splicing

After optical fiber inspection is finished, the fibers will be aligned according to the manner of “core to core” or “clad to clad”, and then is spliced with arc.

• Estimation of splice loss

After fusion splicing is finished, the estimated value of the splice loss will be displayed.

• Screen Data Description:

Core: The left fiber core is offset to the right fiber core. Clad: The left fiber clad is offset to the right fiber clad. Fiber: angle between the left fiber (extension line) and the right optical fiber (extension line) on X (Y) screen. H: Angle between the left (right) fiber and the horizontal line. V: Angle between the left (right) fiber end face and the vertical line.

Saving splice records

Upon the fiber splicing is completed and the loss estimate is displayed, the splice loss value, splice parameters, splicing time and other relevant information will be stored automatically in the machine’s memory. When 4000 splice results have been stored, 4001th result will overwrite the first result.
