In fields with extremely high requirements for polarization state stability, such as fiber optic communications, LiDAR, and quantum sensing, the splicing quality of Polarization-Maintaining Fiber (PMF) directly determines system performance. Traditional splicing equipment often faces pain points such as low alignment accuracy, high splicing loss, and complex operations when processing large-diameter, multi-type PMFs. The S500P1 Large Diameter Fiber Polarizing Welding Machine, with its professional design and powerful performance, provides a comprehensive solution for PMF splicing, from adaptability to stability. 

Core Advantages: Precise Adaptation, High Efficiency, and Stability

• Multi-type Fiber Compatibility:It supports all types of PMF, including panda, bowtie, and elliptic types, while also being compatible with conventional fibers such as Single-Mode Fiber (SMF), Multi-Mode Fiber (MMF), and Dispersion-Shifted Fiber (DSF). It covers the full range of standards from G.652 to G.657, meeting the needs of complex scenarios.
• Large Diameter Processing Capability:It can handle large-core fibers with cladding diameters of 125~500μm and coating diameters of 300~650μm, breaking through the adaptation limitations of traditional equipment for large-size fibers and providing support for applications such as high-power laser transmission and specialty sensing.
• Low Loss and High Stability:The typical splicing loss is as low as 0.02dB (SMF) and 0.01dB (MMF), with a polarization extinction ratio of -30dB and a return loss of ≥60dB. This ensures the efficient maintenance of the polarization state at the splicing point, reducing signal attenuation and interference.

Functional Highlights: Flexible Operation, Intelligent Management

• Independent End-Face Manual Alignment:It adopts a manual end-face observation and alignment system. The 200x magnification clearly presents fiber details, making the operation convenient and fast. It is particularly suitable for laboratory R&D and small-batch customized splicing scenarios, avoiding the adaptation limitations of automatic alignment systems for complex fiber structures.
• Multiple Preset and Customizable Programs:It has 9 groups of factory preset programs built-in, covering common fiber types and splicing scenarios. It also supports user-defined programs (N groups), allowing users to optimize splicing parameters according to special fiber parameters (such as coating thickness and material) to achieve precise "one-fiber-one-strategy" splicing.
• Intelligent Data Management:It can store 10,000 splicing records and 200 groups of splicing images, and supports screen recording of the splicing process, facilitating quality traceability and process optimization. The multi-language display (English and optional languages) lowers the threshold for cross-border team collaboration.

Technical Specifications: Reliable Guarantee Under Strict Environments

• Environmental Adaptability:Operating temperature: -25℃~+50℃, humidity: <95% (non-condensing), altitude: 0-5000m. It can operate stably in harsh environments such as outdoors, high altitudes, and high humidity. Storage temperature: -40℃~+80℃, ensuring the equipment can be quickly put into use after long-term idleness.
• Long-lasting Endurance and Durability:Equipped with a 12V 6.5Ah lithium battery and supporting AC 85-260V wide voltage input, it meets the needs of field operations and scenarios without mains power. The electrode life reaches 5000 discharges, reducing maintenance costs and downtime.

Application Scenarios: Full-Chain Coverage from Laboratory to Industrialization

• Scientific Research Institutions:Used in universities and research institutes for the verification of new PMF structures and low-loss splicing in quantum communication experiments.
• Industrial Manufacturing:Suitable for PMF splicing in fiber lasers, high-power amplifiers, and other equipment, ensuring polarization state stability and output power consistency.
• Specialty Sensing:In systems such as fiber optic gyroscopes and Distributed Acoustic Sensing (DAS), it guarantees the polarization characteristics of sensing fibers, thereby improving measurement accuracy and signal-to-noise ratio.
