Fusion Splicers are the cornerstone of modern fiber optic network construction. Our devices utilize a high-voltage electric arc to melt and seamlessly bond two optical fibers, achieving minimal signal loss and high mechanical strength. Whether you are deploying broad backbone networks or connecting last-mile FTTH drop cables, our NK series splicers ensure precision, speed, and durability in even the harshest field environments (high altitude, wind, or dust).

FAQ: Fiber Optic Fusion Splicers

Q

Which fusion splicer model should I choose, NK4S or NK3S?

A

If you work on backbone or trunk networks requiring extremely low splicing loss, the NK4S (Core-to-Core alignment) is the best choice. For FTTH, drop cables, or short-distance projects where portability and speed are key, the NK3S is highly recommended.

Q

Does the machine support multiple languages?

A

Yes, both models feature a multi-language interface suitable for international engineers. The intuitive GUI makes operation simple regardless of language.

Q

How many splices can I perform on a single battery charge?

A

Our high-capacity 5200 mAh lithium battery typically supports over 340 cycles of splicing and heating on a full charge, ensuring a full day of field work without power anxiety.

Q

What is included in the package?

A

The standard package includes the main fusion splicer unit, fiber cleaver, multi-function stripper, spare electrodes, cooling tray, carrying case, and battery. Contact us for a detailed packing list.

Q

What is the electrode lifespan?

A

The high-quality electrodes are rated for over 5,000 discharges. They are easy to replace, and the machine will prompt you when maintenance is needed.

Q

Do you offer technical support and warranty?

A

Yes, as a leading manufacturer, we strictly test every unit. We provide a comprehensive warranty and remote technical support to assist you with any operational questions or calibration needs.

Q

What is the Minimum Order Quantity (MOQ) for these fusion splicers?

A

As a specialized manufacturer, we focus on wholesale and project-based supply with a standard MOQ of 10 units. This ensures we can provide the most competitive factory-direct pricing, dedicated technical support, and consistent quality control for global distributors and large-scale engineering projects.
