A: The T-402S uses Active Clad Alignment, which aligns fibers by their cladding profile for fast, accurate splicing — ideal for standard FTTH fiber types (G.652D). Q2: How light is the Sumitomo T-402S? A: At just 1.2kg, the T-402S is one of the lightest professional fusion splicers available, making it easy to carry and use in confined spaces like manholes, aerial platforms, and equipment rooms. Q3: Is the Sumitomo T-402S made in Japan? A: Yes. The T-402S is manufactured by Sumitomo Electric in Japan, ensuring the highest standards of build quality and optical performance. Q4: What temperature range can the T-402S operate in? A: The T-402S operates reliably from -15°C to +55°C, making it suitable for cold-climate deployments and hot tropical environments alike. Q5: How does the Sumitomo T-402S compare to the T-400S? A: The T-402S is the updated successor to the T-400S, featuring improved compactness, lighter weight, and enhanced environmental resistance while maintaining the same trusted Sumitomo splicing performance. Q6: What is the electrode life of the T-402S? A: The T-402S electrodes last for 5,000 arc discharges, providing long service intervals and reducing maintenance costs over the splicer's lifetime. Q7: Does the T-402S support both English and Chinese? A: Yes. The T-402S interface supports both English and Chinese language settings.
