3SAE Large Diameter Splicing System - LDS 2.5

Large Diameter Splicing System


The rapid development of photonic technologies has created the need for sophisticated optical products well outside the "telecom standards". Requirements for these photonic components are both increasingly diverse and technically challenging; often they cannot be realized due to the limitations in the glass processing and/or fiber splicing technology.

Utilizing precision engineering, over 20 years of fiber splicing and glass processing experience 3SAE Technologies developed the LDS 2.5, glass processing system. Whether the application is splicing of fiber end caps, tapering, high power fiber laser component fabrication (such as mode field adapters, pump combiners and pump/signal combiners), the LDS 2.5 provides capabilities that overcome the hurdles of current fiber component fabrication processes to meet the most demanding requirements. Designed for reproducibility, precision, and user-friendly operation, the LDS 2.5 provides the user a manufacturing approach to optical component product development. Its extreme flexibility enables customers to realize current and future glass processing and fusion splicing possibilities.

Precision mechanical design, high contrast optics, and absolute control of positional and angular fiber alignment sets the LDS 2.5 apart from competing technologies.

A sophisticated image processing software package allows the user to view, in real time, the progress of a splice or taper. The system handles fiber diameters from 125 to 2.5mm, as well as optics such as prisms, end caps, and lenses, with alignment and fusion of unsurpassed quality. 3SAE Technologies has the ability to offer customized LDS 2.5 systems to meet very specific customer requirements. Please inquire about your specific application.

LDS 2.5 New Features: (Improvements from LDS 2.0)

 


 

Ring of Fire® Technology

Conventional arc fusion machines utilize a high voltage glow discharge between two electrodes, forming a heat source in the shape of a narrow cylinder perpendicular to the fiber. Such heat sources are inadequate for larger fibers, because of the inability to heat evenly.

Flame and filament machines can be optimized to provide circumferential heating, but they also extend the heat zone along the fiber axis. This is advantageous for some applications, such as Thermally Expanded Core splicing (TEC), but causes substantial limitations in the geometries that can be processed. For example, these heat sources are poorly suited for splicing a small diameter fiber to a much larger fiber or optical device (end cap, lens, prism). The heat required to splice the larger object will typically destroy the smaller fiber.

A multi-electrode plasma discharge is advantageous for these applications, as the resulting heat zone is isothermic around the circumference of the fiber, but remains relatively narrow. This allows for precise heating of larger or higher temperature materials. With this system, accurately aligned, high strength splices can be performed without difficulty.
