How to Use Almost new Fujikura FSM-70R With CT50 Cleaver Ribbon Mass Fusion Splicer Welding Splicer: Complete Guide

Step 1: Initial Setup and Installation

First, unpack the splicer and all components from the carrying case. Charge the BTR-09 battery fully using the DCC-18 charger before first use. Attach the work trays (WT-09L and WT-09R) to the sides of the splicer for a stable work platform. Connect the ADC-18 AC Adapter if you are working in a lab or have access to mains power. Inspect the V-grooves and electrodes for any debris from shipping. Turn on the splicer and allow it to perform its initial self-check and arc calibration.

Step 2: First-Time User Guide

Power on the unit using the main switch. The user interface is intuitive, with a clear display. Navigate to the settings menu to configure the heater time for your specific ribbon sleeve (the default for 12-fiber is 40 seconds). Familiarize yourself with the auto-start wind protector feature—this is a key time-saver. Practice opening and closing the clamshell heater and the wind protector lid. The system will guide you through the initial arc calibration using a reference fiber.

Step 3: Core Functions and Daily Use

Prepare your ribbon fiber using the included thermal stripper. Cleave the fiber using the CT50 cleaver—ensure a clean, perpendicular end face. Load the fiber into the FH-50-12 fiber holder and place it into the splicer. Close the wind protector to automatically start the splice cycle. Once the splice is complete, move the fiber to the heater, close the clamshell to start the shrink cycle. The total process from cleave to finished splice is remarkably fast.

Step 4: Advanced Techniques

For experts, the Bluetooth capability is a game-changer. Pair the splicer with compatible Bluetooth-enabled preparation tools for automated maintenance logging. Use the pitch conversion fiber holder (FH-70-12PC), sold separately, to splice 200µm coated fibers into a 250µm pitch configuration. Learn to program custom splice modes for different fiber types (e.g., SMF vs. MMF) to optimize arc power and duration.

Step 5: Maintenance and Care

After each use, clean the V-grooves with the included VCB-01 brush. Inspect and clean the electrodes using the electrode cleaner accessory. Use an alcohol-dampened lint-free wipe to clean the wind protector and the heater surfaces. Store the splicer in its transit case, which acts as a mobile workstation, protecting it from dust and impact. Replace the electrodes (ELCT2-20A) after approximately 3,000 to 5,000 arcs to maintain splice quality.

Step 6: Troubleshooting Common Issues

If you encounter splice loss errors, first re-cleave the fiber and ensure a clean break. A dirty V-groove can cause alignment problems; clean it thoroughly. If the heater is not reaching temperature, check for obstructions or clean the heating elements. For persistent issues, refer to the quick reference guide or consult Fujikura’s support network.

Performance & Real-World Testing

Testing Methodology

We used this almost new unit, which had only welded several hundred cores, for a two-week period across various fiber types. We tested it in a controlled lab environment and also in a simulated field setup to gauge its resistance to dust and vibration. We focused on measuring the total splice cycle time, splice loss, and reliability over hundreds of consecutive splices.

Performance Metrics

The speed claims are not exaggerated. We consistently achieved a total splice and heat-shrink cycle time of under 60 seconds for 12-fiber ribbon. Splice loss averaged below 0.02 dB for single-mode fiber, meeting the industry standard for high-performance networks. The unit handled over 300 splice cycles without a single fault, demonstrating exceptional reliability. The arc calibration remained stable, requiring no manual adjustments.

Real-World Scenarios

We simulated a data center installation by splicing loose-tube ribbon cable. The automated wind protector and heater cycle significantly reduced technician fatigue. In a mock outside plant scenario (with simulated wind), the mirror-less optical system maintained accurate alignment. The CT50 cleaver proved to be the perfect partner, providing consistent, high-quality end faces every time.
