An optical fiber fusion splicer is also called a fusion splicing machine.

A fusion splicer is a specialized device used to permanently join two optical fibers end-to-end by melting their ends together, typically using an electric arc, to create a seamless, low-loss connection (fusion splicing) . In industry contexts, it is commonly referred to as a fusion splicing machine, emphasizing its automated or semi-automated functionality for aligning and fusing fibers .

Key Features and Terminology

• Core Function: Aligns fiber cores precisely and fuses them to minimize optical loss and back reflection .
• Alignment Methods: Can use optical core alignment (profile alignment) or cladding alignment, depending on the model and application .
• Protective Measures: Often includes a heating device to shrink protective sleeves over the splice for durability and environmental protection .
• Applications: Widely used in telecommunications, data centers, broadband networks, and high-speed fiber deployments . In summary, while fusion splicer is the most common term, it is interchangeably called a fusion splicing machine, both referring to the same device that performs the fusion splicing process.
