Step 1: Initial Setup and Installation

First, charge the BTR-09 battery fully using the DCC-18 charge cord and ADC-18 AC adapter. While it charges, set up your workstation using the CC-24 transit case. Open the case and position it as a stable base. Mount the splicer and the CT-08 cleaver on the designated spots. Connect the splicer to power if you prefer to use the AC adapter during setup. No complex calibration is needed out of the box, but you should check for any software updates via a USB connection to your computer.

Step 2: First-Time User Guide

Press the power button to turn on the splicer. The user interface is intuitive, with a clear color LCD. Navigate to the settings menu to select your fiber type (e.g., SM, MM, DSF). The default settings are excellent for most single-mode applications. Familiarize yourself with the “Splice” and “Heat” buttons on the panel. We recommend running a few test splices on scrap fiber to ensure everything is functioning correctly before you start a critical job.

Step 3: Core Functions and Daily Use

Prep your fibers according to standard procedures (strip, clean, cleave). Use the CT-08 cleaver for a precise end face. Place the prepared fibers into the appropriate fiber holders or sheath clamps. Close the wind protector. The auto-start feature will begin the splicing process as soon as the fibers are properly aligned. In seconds, you will see the estimated loss on the screen. After the splice, load it into the heater with a sleeve and close the cover. The heater also has an auto-start feature, beginning its 23-second cycle immediately.

Step 4: Advanced Techniques

For experienced users, the 62S+ offers several advanced options. You can manually adjust the splice parameters, such as arc power and prefusion time, for non-standard fibers. The “Active Core Alignment” system can be observed on the screen, giving you visual feedback. Another pro tip: use the splice data storage feature to log all your splices for quality assurance reports. You can download this data via USB.

Step 5: Maintenance and Care

Regular maintenance is vital for consistent performance. After every 500 splices, clean the V-grooves and electrodes using the included alcohol pot and a lint-free wipe. The mirrorless optical system is less prone to issues, but you should still keep the splice chamber clean. Replace the electrodes after about 5,000 splices. The splicer will prompt you when it is time for a replacement.

Step 6: Troubleshooting Common Issues

If you encounter high loss readings, first re-cleave the fiber and try again. Check the V-grooves for dirt or debris. If the splicer isn’t performing a splice at all, verify that the fibers are properly seated and that the wind protector is fully closed. For persistent error messages, the built-in diagnostics can help you identify the problem. You can also refer to the video instruction manual for visual assistance.

Expert Tips for Maximum Value

To get the most out of your Fujikura FSM-62S+, follow these expert tips we learned during our testing.

Tip #1: Keep the V-Grooves Immaculately Clean

This is the number one cause of splice loss. Develop a habit of cleaning them every 100 splices. Use the included alcohol pot and a professional-grade lint-free swab.

Tip #2: Master the CT-08 Cleaver

The included cleaver is excellent. Learn to use it effortlessly. A perfect cleave angle is the foundation of a low-loss splice. Practice your cleave technique.

Tip #3: Use a Good Stripper

Invest in a high-quality fiber stripper like the Miller 142S or similar precision tool. A bad strip can introduce micro-cracks and lead to failures.

Tip #4: Calibrate for Different Fibers

Don’t assume the default settings are perfect for every fiber. If you switch to a different brand or type (e.g., BendInsensitive fiber), take a moment to run the auto-calibration function.

Tip #5: Manage Your Batteries

Always carry a second, fully charged BTR-09 battery. While 200 cycles is a lot, nothing stops a job faster than a dead battery. Rotate your batteries to prolong their lifespan.

Tip #6: Update the Firmware Regularly

Fujikura releases updates that can improve splice algorithms and add new features. Set a reminder to check for updates every few months via the Fujikura website.

Tip #7: Use the Splice Data Logging
