LDMLAX A-87S Fusion Splicer User Manual

1. Introduction

The LDMLAX A-87S Fusion Splicer is an advanced optical fiber hot melt machine designed for efficient and precise fiber optic splicing. It integrates features such as fast splicing, rapid heating, and a high-capacity battery, making it suitable for various optical fiber and cable projects. This manual provides detailed instructions for the safe and effective operation, maintenance, and troubleshooting of your A-87S Fusion Splicer.

2. Safety Information

Always observe the following safety precautions to prevent injury and damage to the device:

• Do not expose the splicer to extreme temperatures, humidity, or dust.
• Ensure the work area is well-ventilated.
• Handle optical fibers with care. They are fragile and can cause splinters.
• Avoid direct eye exposure to the arc discharge during splicing.
• Use only the provided power adapter and accessories.
• Keep the device away from flammable materials.

5. Operating Instructions

5.1 Fiber Preparation

1. Strip the Fiber: Use a fiber stripper to remove the coating layer from the optical fiber. For coating layers below 250µm, strip approximately 8-16mm. For 250µm-1000µm, strip approximately 16mm.
2. Clean the Fiber: Use an alcohol wipe to thoroughly clean the bare fiber.
3. Cleave the Fiber: Use a high-precision fiber cleaver to cut the fiber end at a perfect 90-degree angle. A clean cleave is crucial for successful splicing.

5.2 Splicing Process

1. Place Fibers: Open the splicer lid and carefully place the prepared fibers into the V-grooves of the multifunctional fixture. Ensure the fiber ends are positioned correctly for alignment.
2. Close Lid: Gently close the splicer lid. The automatic core alignment system will begin to align the fibers.
3. Initiate Splicing: The splicer will automatically initiate the splicing process. The typical connection time is 9 seconds. The display will show the splicing progress and estimated splice loss.
4. Inspect Splice: After splicing, the splicer will display the splice loss. A typical splice loss for SM (G.652) fiber is 0.02dB. Inspect the splice visually on the screen.

5.3 Heat Shrinking

1. Position Heat Shrink Tube: Slide a heat shrink tube over the spliced joint.
2. Place in Heater: Carefully transfer the spliced fiber with the heat shrink tube to the built-in heating oven.
3. Initiate Heating: Close the heater cover. The typical heating time is 26 seconds, but this can be adjusted in the settings.
4. Remove and Cool: Once heating is complete, carefully remove the fiber and allow the heat shrink tube to cool and harden.

6. Maintenance

• Electrode Cleaning: Regularly clean the electrodes with a cotton swab dipped in alcohol to ensure optimal performance. Replace electrodes when they show signs of wear or after approximately 3000 splices.
• V-Groove Cleaning: Keep the V-grooves clean from fiber debris and dust. Use a soft brush or compressed air.
• Display Cleaning: Clean the LCD display with a soft, dry cloth. Do not use abrasive cleaners.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Store the splicer in a cool, dry place when not in use.
