With its low profile and new super rugged body, the FITEL® S123 Version 2 Series Fusion Splicer offers speedy operation for FTTX, LAN, backbone or long-
haul installations. The lightweight, durable metal body frame and rubber protection corners provide robust protection, enabling use in challenging locations with-
out compromising splicer performance.  The S123 v2 Splicer is water resistant to IPX2 and dust resistant to IP5X.

A large battery capacity makes it possible to perform up to 70 cycles of splicing and heating for the S123C/M4 v2 models with a single battery, and 160 cycles for the S123M8/M12 v2 models with a dual battery configuration.

Combining  portability,  power  flexibility  and  field  ruggedness, the S123 v2 Splicer delivers fast and consistent splicing with outstanding mobility and extreme ease-of-use. It also offers a splice-on-connector (SOC) solution.

Under Tough Environments

N/A The S123 passed manufacturer testing based on criteria below (Above tests were performed at the manufacturer's 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
  • Water resistant - IPX2 rating drip proof (IPX2 rating drip proof means that the machine can be exposed to 3 mm/min drip from 4 different angles with 15° tilt for 2.5 min each and still functions.)
  • 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 functions.)
