The FITEL® S178 Version 2 Hand-Held Core-Alignment Fusion Splicer is the latest, state-of-the art addition to the S17X series of splicers. By combining speed, precision, durability and portability in one unit, the S178 ver.2 Fusion Splicer ushers in an entirely new range of applications for core alignment splicing.

The S178 ver.2 Fusion Splicer has been enhanced with new features to promote ease of use. The splicer is updated to automatically charge the battery internally (when connected to AC main power) even during operation. The new illumination lamp lights up a wide area around the V-grooves and improves operation in low light environment. The redesigned and strengthened heater simplifies the protection sleeve loading process.

Equipped with a new alignment system that can save up to 20% on splicing time, the S178 ver.2 Splicer’s improved heating mechanism can also reduce protection sleeve shrink time by more than 30%. In addition, a newly incorporated USB 2.0 interface speeds PC communication and image/video transfer, while enhancing reliability.

Under Tough Environments

N/A The S178 ver.2 passed testing based on criteria below (Tests to the left were performed at Furukawa Electric Co. Labs, and do not guarantee that the machine will be undamaged under these conditions):
  • Drop resistant - 76 cm drops from 5 different angles (IPX2 rating drip proof means that the machine can be exposed to 3 mm/min drip from 4 different angles with 15º tilt for 2.5 min each and still function)
  • Water resistant - IPX2 rating drip proof 5
  • Dust resistant - IP5X rating dust proof (IP5X rating dust proof means that the machine can be exposed to dust particles with a diameter of 0.1 to 25 µm for 8 hours and still function)
