Expanded beam connector

摘要

An optical connector comprises a lens (101) and a ferrule assembly (102) including a ferrule (103) with an endface (103a). At least one fiber (104) in the ferrule has a fiber end (104a) presented at the endface. A housing (105) holds the ferrule assembly and the lens in a certain axial and radial relationship. A glass element (106) has a first surface (106a) and second surface (106b). The first surface is affixed to the endface such that the first surface is in physical contact with the fiber end. The second surface has an antireflective coating and defines a space (107) between the second surface and the lens.
