Precision Drawn Borosilcate Glass Ferrules

Featured Product from Accu-Glass

Whether a single fiber is terminated at a device or joined to another fiber, a ferrule or connector of some type is commonly used. These must be high precision parts that ensure the fiber is optimally aligned. If this is not the case, the light signal will be scattered and the signal will be dampened or lost. Therefore, fiber optic ferrules perform a critical role in the use of fiber optics in today's world.

Precision drawn borosilicate glass tubing made by Accu-Glass is used in connector ferrule applications. For example, Accu-Glass manufactures one product that has an ID (inside diameter) of 127 microns with a tolerance of ± 1 micron. The tubing can be manufactured through our conventional direct draw process or via our redraw process. The tubing can be precision cut to length using a process which employs diamond blades.

For fiber optic ferrules Accu-Glass can also use a proprietary process to form an inner funnel in one end which helps guide the fiber into the ferrule. Polishing the end of the fiber is a critical element and can greatly impact the quality of the installation.

Borosilicate glass ferrules are the ideal material for superior polishing. The Accu-Glass borosilicate glass ferrule and the glass from which fibers are constructed polish at similar rates. Therefore, the finished end of the glass and the fiber end up being smooth with minimum under cut.
