Setup and Installation
Proper installation of electrodes is crucial for optimal splicer performance and safety. Always handle electrodes with care to avoid damage or contamination.
- Safety First: Power off the fusion splicer and disconnect it from the power source before beginning any maintenance or installation. Allow the splicer to cool down if it has been recently used.
- Locate Electrodes: Open the splicer's top cover and locate the electrode assembly. Refer to your specific Ericsson splicer's manual for exact location and access.
- Remove Old Electrodes: Carefully loosen the screws holding the old electrodes in place. Use tweezers or a non-magnetic tool to gently remove the old electrodes. Dispose of them properly.
- Install New Electrodes: Unpack the new VIJEI electrodes. Avoid touching the electrode tips with bare hands to prevent contamination. Insert the new electrodes into their respective holders, ensuring they are correctly oriented and seated.
- Secure Electrodes: Gently tighten the retaining screws to hold the electrodes firmly. Do not overtighten, as this can damage the electrodes or holders.
- Close Cover: Close the electrode cover and the splicer's top cover.
- Arc Calibration: Power on the splicer. It is essential to perform an arc calibration (also known as arc test or arc discharge calibration) after replacing electrodes. This process adjusts the arc intensity for optimal splicing performance. Consult your Ericsson splicer's user manual for detailed instructions on performing arc calibration.


Operating Instructions
Once the new electrodes are installed and arc calibration is complete, your fusion splicer is ready for operation. The electrodes generate the arc necessary to melt and fuse optical fibers.
- Fiber Preparation: Ensure optical fibers are properly cleaved and cleaned according to your splicer's instructions.
- Splicing Process: Place the prepared fibers into the splicer's V-grooves. The splicer will automatically align the fibers and initiate the fusion process, during which the electrodes will discharge an arc.
- Splice Inspection: After fusion, inspect the splice for quality using the splicer's built-in magnification or an external microscope.
- Electrode Lifespan: Electrodes have a limited lifespan, typically measured in the number of splices. Replace them when the splicer indicates a need for replacement or when splice quality degrades consistently despite cleaning and calibration.

Maintenance
Regular maintenance of your electrodes will extend their lifespan and ensure consistent splice quality.
- Cleaning: Periodically clean the electrode tips using a lint-free swab moistened with isopropyl alcohol (99% or higher). Gently wipe the tips to remove any dust, fiber debris, or carbon buildup. Allow to air dry completely before use.
- Inspection: Visually inspect the electrode tips for signs of wear, pitting, or damage. Worn electrodes will appear blunt or have visible craters. Replace electrodes if significant wear is observed.
- Storage: When not in use, store spare electrodes in their original protective packaging in a clean, dry, and dust-free environment. Avoid exposing them to extreme temperatures or humidity.
Troubleshooting
If you experience issues with splicing, consider the following common problems related to electrodes:
- Poor Splice Quality (High Loss, Bubbles, Bad Shape):
- Dirty Electrodes: Clean the electrode tips as described in the Maintenance section.
- Worn Electrodes: Inspect for wear and replace if necessary.
- Incorrect Arc Calibration: Perform an arc calibration procedure.
- Improper Fiber Preparation: Ensure fibers are cleaved and cleaned correctly.
- Electrode Breakage:
- Improper Handling: Handle electrodes with care, avoiding excessive force during installation or cleaning.
- Excessive Use: Electrodes have a finite lifespan. Replace them when they reach their recommended splice count.
- Splicer Error Codes Related to Electrodes: Refer to your Ericsson fusion splicer's specific error code manual for diagnosis and resolution.
User Tips
No specific user tips were available from reviews or Q&A for this product. However, general best practices for fusion splicer electrodes include:
- Always keep a spare set of electrodes on hand to avoid downtime.
- Document the number of splices performed with each set of electrodes to anticipate replacement needs.
- Use only high-purity isopropyl alcohol for cleaning.
