Beschreibung
Zusammenfassung:The end face of an optical fiber assembly consisting of an optical fiber s and a ferrule f is polished to form a conical surface with oblique faces Fp1 and Fp2 such that, central axis Ap of said conical surface makes an inclination of 8 DEG with respect to the optical axis L of said optical fiber s, top Ft of said conical surface coincides with the optical axis L of said optical fiber s, and has a taper angle of 2 DEG . Thereafter, said optical fiber assembly is further polished to form an oblique convex spherical surface at the end face such that, central axis of said oblique convex spherical surface makes an inclination of 8 DEG with respect to the optical axis L of said optical fiber s. Due to this, insertion loss and light reflected back to the source is stabilized and minimized.
