Splicing Machine (Fusion Splicer)

Splicing Machine (Fusion Splicer)

A professional fusion splicing machine (often called a "splicing machine" in the field) is a precision electro-optical instrument used to permanently join two optical fibers by melting (fusing) them together with an electric arc. This process creates a continuous, low-loss, and high-strength connection that is essential for modern fiber optic networks. The machine first aligns the prepared fiber ends—either by cladding alignment (faster, suitable for most single-mode fibers) or core alignment (more precise, using cameras and image processing to directly align the fiber cores, resulting in splice losses as low as 0.02 dB). After alignment, a precisely controlled electric arc melts the fiber ends, and the machine pushes them together to form a seamless splice. An integrated heater then shrinks a protective sleeve over the splice. Modern splicing machines feature a high-resolution color touchscreen (4-5 inches), automated arc calibration, wind protection, and a ruggedized design for field use. A rechargeable lithium battery typically supports 200-300 splices per charge. These machines are an indispensable tool for outside plant crews, FTTH installers, central office technicians, and any professional performing permanent fiber optic cable joins, repairs, or pigtail attachments.

• Splicing Mode: Core alignment (core-clad concentricity alignment for lowest loss) or Cladding alignment (faster, more affordable)
• Fiber Types: Single mode (SM, G.652, G.657), Multimode (MM, G.651), Dispersion Shifted (DSF, G.653), Non-Zero Dispersion Shifted (NZDSF, G.655)
• Splice Loss: ≤0.02 dB (typical for SM core alignment), ≤0.01 dB (MM), ≤0.05 dB (cladding alignment)
