Preventive Maintenance, High Speed Dual Independent Heaters, Proven Field Toughness, Extended Battery Life for 320 Cycles
The Sumitomo Q502S is a high-performance active clad alignment fusion splicer designed for speed, precision, and rugged field use. It features advanced automation technologies such as NanoTune™ AI, which improves splicing accuracy regardless of operator experience or environmental conditions. The Q502S is equipped with a range of innovative capabilities to streamline fiber preparation and splicing workflows.
The included lightweight work tray is designed for immediate use straight out of the carrying case and offers an integrated cooling tray and removable waste bin. It supports both FC-6+ and FC-8R cleavers, includes metal plates for fiber holder stability, and provides tool cutouts to keep essential items organized and within reach. It can be operated using straps, mounted on a tripod, or directly within the case for field flexibility.
Hot Core Analyzing technology ensures accurate estimated splice loss by capturing high-resolution fiber imagery during fusion. The Q502S is also the first fusion splicer to offer automatic MMF/SMF fiber type detection, eliminating user error when selecting splice programs.
With SumiCloud™ wireless connectivity, the Q502S allows remote firmware updates, cloud-based reporting, preventive maintenance notifications, and remote locking via a web interface—enhancing fleet management and field visibility.
Additional features include:
6-second splice time and 12-second heat time
Long-life battery supporting up to 250 splice/heat cycles per charge
Electrodes rated for up to 6,000 arcs
Rugged IP52-rated design for drop, water, and dust resistance
4.3-inch TFT color LCD with fully touch-navigable interface
The Sumitomo Q502S offers a complete, field-ready solution for precision splicing in demanding environments, combining intelligent features with ergonomic design for maximum productivity.
