1. Core Cutting: Fly Laser UV Cold Processing Technology Eliminates Thermal Damage

Feila Laser utilizes its proprietary 355nm UV laser cutting system (Model FL-UV300), utilizing the cold processing principle of "photons directly breaking molecular bonds" to achieve three major breakthroughs:

- Cutting Accuracy of ±0.005mm: Precisely cuts conductors without damaging adjacent insulation layers, solving the challenge of cutting multiple conductors with close spacing (as little as 0.2-0.5mm);

- Heat-Affected Zone (HAZ) <2μm: Far below the industry standard of 3μm, this completely prevents carbonization and shrinkage of the insulation layer due to high temperatures, ensuring impedance stability (typical impedance is controlled at 100Ω ±5%, exceeding the industry tolerance of ±10%);

- Cutting Flatness Ra <0.15μm: Greater conductor cross-section smoothness reduces reflection loss during signal transmission, paving the way for high-frequency signal transmission (800G and above).

Performance Guarantee: Leveraging cold processing technology and comprehensive process control, Fly Laser's QSFP high-speed cable cutting meets the high-frequency transmission requirements of large-scale infrastructure scenarios such as data center "East-West Computing."

Summary: The Core Advantages of Fly Laser Technology

Fly Laser's QSFP high-speed cable cutting process is more than a simple "cutting" operation. Instead, it's a precision manufacturing solution based on proprietary UV laser technology, dual-vision positioning, and integrated inspection. Ultimately, it achieves "damage-free cutting, zero signal attenuation, and zero interface deviation." This not only meets the performance requirements of QSFP high-speed cables, but also makes Fly laser a key process partner for high-frequency communication equipment companies to enhance their product competitiveness.
