Single-mode pigtail ferrule FSPN-633-0

The Fiber Optic Pigtail Ferrule is composed of optical fiber, a micro glass tube, and adhesive. The adhesive is typically a two-component thermosetting epoxy resin with low coefficient of thermal expansion (CTE) and high bonding strength. At the tail where the fiber contacts the micro tube, a soft adhesive is applied to protect the fiber from fracture caused by movement. A 0°-polished facing angle ferrule pigtail, when matched with a 0°-angled lens, minimizes deviation of the collimated beam output from the optical axis, making it ideal for applications requiring precise alignment and coupling. Despite the Anti-Reflection Coating on the surface, the return loss caused by reflected light from the planar surface remains slightly higher than that of the 8° facing angle. Users with strict return loss requirements should opt for the 8° facing angle pigtail.
