Clean Your Fusion Splicer

Clean Your Fusion Splicer

Cleaning your fusion splicer every day helps it work well. This habit keeps your fusion splicer safe and stops repairs. Daily cleaning makes splicing better and helps your tools last longer.

Daily Cleaning Steps

Here are steps to clean your fusion splicer and tools:

  1. Use a big cotton rag to wipe dust and grease off the shell. For small spots, use cotton swabs with alcohol.

  2. Turn off the power. Open the windproof cover. Clean the lens with a cotton swab dipped in alcohol. Start at the center and move out. Dry the lens with a clean swab.

  3. Blow dust off the V-groove with clean air. Wipe it with alcohol. Use a thin cotton swab or stripped fiber with alcohol for tough dust.

  4. Take out the electrodes. Wipe them with an electrode cleaning sheet and a cotton swab with alcohol. Put them back in and use the splicer menu for discharge cleaning.

  5. Clean the fiber cleaver parts—clip, anvil, and blade—with a cotton swab and alcohol. Do this if fiber pieces are left behind.

Cleaning every day takes just a few minutes. It helps you avoid expensive fusion splicer repair. Always use the maker’s cleaning steps for the best results.

Specialty Fusion Splicer Daily Cleaning

For Shinho specialty fusion splicers like S-12PM, S-22, S-27, S-37, and S-100, daily cleaning is very important. Use lint-free cotton buds and alcohol wipes to clean the V-grooves, electrodes, and fiber cleaver after each job or at the end of the day. Be careful when you change fiber types or work in dusty places. Do not use strong or wrong cleaning liquids. This keeps your warranty and machine safe. For special instructions, check the Shinho official user manual or download center.

V-Groove and Electrode Care

Keep the V-grooves and electrodes clean for good splicing. Dirt can make the fibers line up wrong and cause high splice loss. Clean the V-grooves with alcohol wipes or special lint-free swabs. Do not use cotton swabs because they leave lint. For tough dirt, use a dry or damp swab with the right cleaner.

Key Points for V-Groove and Electrode Maintenance

  • Look for dust, dirt, or leftover stuff on V-grooves and electrodes before and after you use them.

  • Use the cleaning brush or a lint-free swab with alcohol to clean without scratching.

  • For tough dirt, use the cleaning steps and tools the maker suggests.

  • Cleaning often keeps splicing good and helps your fusion splicer last longer.

  • Shinho specialty fusion splicers are easy to clean. Daily cleaning is quick and stops expensive repairs.

Tip: Clean deeply every week and get professional help once a year. This keeps your fusion splicer and tools working their best. Good cleaning helps you get clean fibers and great fusion splicing.

Inspect and Replace Parts

Check your fusion splicer often to keep it working well. Change old parts when needed so problems do not get worse. This helps you save money and stops surprise repairs. Pay attention to the parts that help fibers line up and splice right.

Check Electrodes and V-Grooves

Always look for damage before you use your fusion splicer. Here are signs that electrodes or V-grooves need help:

  1. Glass from many uses can stick to the V-groove and electrode rods. This makes fibers not line up and causes more splice loss. Cleaning might not fix this.

  2. If errors keep happening after you clean the V-groove, you should replace it.

  3. If you splice fibers with different spacing than your V-groove, you need a new V-groove.

Look at the V-groove for dust or dirt that can block fiber clamping. Clean it with a thin cotton swab and alcohol. If dirt stays, use a cleaved fiber to get it out, then clean again. Check the fiber clamp for dust and clean it with an alcohol swab, then dry it. Always check electrodes for rust or wear. Bad electrode contact or rust can make discharge weak and mess up fiber alignment.

Tip: Dirty or old electrodes and V-grooves make fibers line up wrong, cause high splice loss, and make splicing not work well. Change them when you see these problems.

Replace Worn Components

Look at the blade and clamp pads before you use your fusion splicer. If you see "large cleave angle" or "bad cleave angle" errors, or if the fiber will not cleave, check these parts fast. Change them if they are broken or if cleaning does not help. Old blades and clamp pads can make fibers not line up and cause bad splicing.

Write down when you change electrodes, blades, and other parts. Change electrodes every 1,000 to 1,500 uses to keep splicing good. A log helps you remember when to clean, change, or adjust parts. This habit helps your fusion splicer last longer and keeps your care on track.

Shinho specialty fusion splicers are easy to clean and fix. Doing these steps helps fibers line up right and keeps your splicer working great.

Fusion Splicer Calibration

Fusion Splicer Calibration

When you keep your fusion splicer calibrated, it works right. This helps every splice meet the rules for the job. You save money and stop long breaks by checking calibration often.

Annual Calibration

Calibrating your fusion splicer once a year keeps it working well. You should get it checked and fixed every year or after 3,000 to 5,000 arcs. This means cleaning, looking at, and changing old parts like electrodes, V-grooves, fiber clamp chips, and motors. If you skip this, your fibers may not line up. You could get high splice loss and other problems.

  • Yearly care includes:

    • Cleaning inside parts very well

    • Checking and changing old parts

    • Making sure motors and cameras line up

    • Updating software for best use

Tip: Keep your fusion splicer in a dry, cool place. This stops rust and keeps calibration good.

Experts say to clean every day and calibrate fully every six months. Doing this stops problems like “waisting,” “necking,” and more splice loss. Your splicer will work better and last longer.

Adjust Arc Settings

Setting the arc right is important for good splicing. Before each job, do an arc test. This helps your fusion splicer set arc power for the weather. Always use the right settings for your fiber type.

To set arc settings, do these steps:

  1. Do an arc test to set arc power for your area.

  2. Make sure splicing and heating match your fiber.

  3. Check the cleaver blade is sharp and clean.

  4. Change electrodes if the arc gets weak.

  5. Clean V-grooves, fiber clamps, and lenses often.

If you see calibration problems, try these fixes:

  • Clean fiber ends with lint-free wipes and alcohol

  • Check fiber lines up in the V-grooves

  • Clean or change dirty electrodes

  • Change arc power and fusion time for your fiber

  • Make sure your splicer matches your fiber type

  • Keep your work area clean and free of dust

Note: Old electrodes can make arcs go sideways and cause bad splices. Change them after 1,000 to 1,500 splices or sooner if you work in tough places.

Checking calibration and arc settings often helps you get good fiber alignment and strong splices every time.

Storage and Environment

Proper Storage

You must keep your fusion splicer in a safe place. Pick a spot that is dry and cool. Do not put it in the sun or near heat. Use a strong case or bag to protect it from dust and bumps. Take out the battery if you will not use it for a long time. Charge the battery every few weeks so it does not lose power. Before you use it, check all the parts to make sure they work.

  • Keep your fusion splicer in a clean, dry spot.

  • Do not let it get too hot or too cold.

  • Use a tough case when you move or store it.

  • Take out the battery and care for it if not using.

Tip: Shinho specialty fusion splicers have cases made to keep them safe. Using the right case helps stop drops and keeps your machine working well.

Protect from Dust and Moisture

Dust and water can hurt your fusion splicer. Never use compressed air to clean it. Compressed air can add water and bring in more dust. Use lint-free wipes and the right cleaner for fibers and tools. Work in a safe place like a tent, truck, or trailer when outside. Always clean your tools before you use them to keep dirt away.

  • Do not use compressed air to clean.

  • Use lint-free wipes and safe cleaners.

  • Work in safe places when you can.

  • Clean tools before using to stop dirt.

Fiber optic splice protection sleeves keep out dust and water. These sleeves use heat and glue to seal the splice. Clean the sleeves before you use them and put them on with care. This keeps air bubbles out and protects your fiber joints for a long time.

Note: Shinho splicers like S-22 and S-100 are made for hard jobs. You still need to keep them safe from dust and water for the best results.
