It can be incredibly frustrating when you're in the middle of splicing fibres, and suddenly, the splicing screen goes blurry or fails to show the fibres clearly. So, what should you do? The first thing is to stay calm (yes, even though you might want to toss the fusion splicer out the window). These issues are usually easy to solve with a bit of troubleshooting. 
 

Clean the Screen and Fibre Holder 

Sometimes, the simplest solution is the right one. If the screen is blurry or the fibres aren't showing clearly, it could be due to dirt, dust, or oils on the screen or the fibre holder. Clean the screen using a soft microfiber cloth designed for electronic devices. Also, make sure the fibre holder is free from debris. A simple wipe could save you from a lot of frustration. 

Check for Calibration Issues 

If cleaning doesn't help, the next step is to check your fusion splicer's calibration. Over time, the splicer might need recalibration to ensure proper functioning. If your model has a self-calibration feature, run it to see if that resolves the issue. If not, you may need to contact the manufacturer for assistance. 

Inspect the Fibre Strippers and Tools 

A blurry image could also result from improper fibre preparation. If the fibres aren't stripped cleanly, they can cause poor fusion and unclear readings on the screen. Double-check your fibre stripper for damage and ensure you prepare the fibres properly. 

Adjust the Focus 

It might sound like an obvious solution, but sometimes, the focus on the splicing screen gets accidentally altered. Make sure the focus settings are correct. If you're unsure how to adjust the focus on your fusion splicer, consult the user manual or contact your equipment provider for assistance. 

Restart the Fusion Splicer 

If all else fails, try turning the fusion splicer off and on again. A simple reboot can fix temporary software glitches or refresh the display, clearing up blurry visuals. 

Wrapping Up 

Fusion splicer screen issues don't have to be a nightmare. With a few checks and quick fixes, you can often resolve blurry screens and get back to work quickly. Just remember to clean, calibrate, and check your tools. And if nothing works, don't hesitate to call in the pros (we're always here at CMW if you need advice or to hire new equipment). 

FAQs 

Why is the screen on my fusion splicer blurry? 

The screen might be blurry due to dirt, oil, or dust on the screen or fibre holder. Cleaning the screen and fibre holder should fix this issue. If the problem persists, it could be a calibration issue or focus misalignment. 

How do I calibrate my fusion splicer? 

Most fusion splicers have an automatic calibration function. Check the user manual for specific instructions on recalibrating your model. If manual calibration is needed, follow the steps carefully to ensure the device functions properly. 

How can I clean the screen of my fusion splicer? 

Use a soft microfiber cloth to clean the screen gently. Avoid harsh chemicals or rough materials, as they could scratch the screen. 

Can poor fibre preparation cause a blurry splicing screen? 

Yes, improper fibre preparation, such as unclean stripping or damaged fibres, can result in poor fusion, causing the splicing screen to show unclear results. 

What should I do if the issue persists after cleaning and calibration? 

If cleaning and calibration don't resolve the issue, it may be time to contact the manufacturer or a service technician. It could be a deeper issue requiring professional inspection or repair. 

By following these maintenance checks and troubleshooting steps, you can avoid letting blurry screens derail your work. Keep your fusion splicer in top shape and keep those fibres looking sharp.
