This Fujikura FSM-70S fusion splicer is in very good cosmetic condition and has been tested and confirmed fully functional. The unit is running firmware version 01.54 and has a total splice count of 7,363, with an arc count of just 52 since the last service. The unit has undergone authorised Fujikura servicing, with the last service completed on 24 March 2026 and the next service not due until 24 March 2027.

This item is supplied as a kit and includes:

• Fujikura FSM-70S fusion splicer
• Fujikura CT-30 high precision fibre cleaver
• AC adapter / mains charger
• DC output cable
• CC-30 transit / carry case

The Fujikura FSM-70S is a fully ruggedised, core alignment single-fibre fusion splicer, providing consistent, low-loss splice performance. Designed to be more ergonomic, faster, and more durable than the 60S series, it reduces splicing time to just seven seconds and achieves a total splice cycle of approximately 21 seconds.

Key highlights:
- Programmable automated wind protector opens and closes automatically to initiate and complete the splice process
- Auto-open sheath clamps release fibre after tensile test to streamline workflow
- Clamshell-design tube heater applies heat to both sides of the protection sleeve for a 14-second shrink time
- Mirrorless optical system and severe-impact-resistant monitor for maximum durability
- Withstands a 762 mm (30 inch) drop test; resistant to shock, dust, and rain
- Li-Ion battery supports up to 200 splices and shrinks per charge
- Dual-camera 4.7-inch TFT colour LCD with front or rear display options and automated image orientation
- Stores last 2,000 splice results in internal memory
- Built-in on-device training videos
- Compatible with AFL FuseConnect splice-on connectors
- Made in Japan
