The Sumitomo S1V (and its successor, the S1V Ultra) is a highly compact, active clad alignment fusion splicer specifically designed for high-precision FTTx (Fiber to the Home/Business) field applications. As of 2026, it remains one of the smallest and most portable splicing machines globally, optimized for fast deployment in broadband networks.
Core Performance Features
NanoTune™ Technology: Uses artificial intelligence to refine splicing algorithms, enabling the machine to successfully join fibers even with poor cleaves or minor damage.
Rapid Processing: Delivers a typical splice time of 6 seconds (SM Quick Mode) and a fast heating time of 12 to 17 seconds for a 60mm sleeve.
Active V-Groove Alignment: Compensates for environmental factors such as dust or fiber eccentricity, ensuring a low typical insertion loss of 0.03dB for single-mode fiber.
Extended Consumable Life: Features industry-leading electrode life, rated for 6, 000 arc discharges.
