D80 fiber patch cords use high-precision D80 connectors or modified D80 connectors with air-gap protection, assembled with large-core power-delivery fibers whose end faces are finely ground and polished. They are mainly used to transmit power in semiconductor laser modules and low- to medium-power solid-state lasers. An environmentally friendly adhesive-free process inside the connector further improves fiber heat dissipation and service life, meeting high-power transmission requirements for laser welding and cutting. Fujin Optoelectronics also provides custom fiber patch cords and coating services for customer-supplied patch cords, such as SMA905 and FC/PC patch cords.

Pump-Laser Pigtails and Patch Cords Flexible Transmission for High-Power Laser Processing Medical Laser Equipment Industrial Laser Processing
A unique grinding, polishing, and assembly process developed by Photonstream. Imported high-quality large-core silica fiber. Coated fiber end faces with a high damage threshold (> 200 megawatts per square centimeter). A metal-armored protective sleeve resists crushing, surface abrasion, shearing, and tension. Fiber ferrules made of stainless steel or cupronickel serve as heat sinks to effectively dissipate heat generated by the fiber. Air-gap ferrule assembly with the fiber suspended eliminates the effects of energy-absorbing materials near the fiber end face, such as adhesives, connector materials, and coatings, making it ideal for high-power lasers.
