Embodiment Construction

[0073] Embodiments described herein relate to optical assemblies, lens-based connectors, and methods of manufacturing optical assemblies and lens-based connectors. Embodiments of the present disclosure position a precisely matched lens array in front of the fiber endface and enable connector-to-connector mating in the axially and laterally permitted expanded beam space. More specifically, embodiments provide High Fiber Count Extended Beam Connectors (HFC / EB) that have precisely formed matching arrays of holes and lenses, precisely and permanently connecting these two elements with their mating optical fibers Such subassemblies are mounted together and contained in a connector body that controls all necessary degrees of freedom for successful optical coupling. Embodiments ensure accurate positioning of the lens array and fiber array within the body of a lens-based optical connector such as an HFC / EB connector.

[0074] The embodiments described herein effectively establish a s...

Abstract

Ferrule assemblies having a lens array are disclosed. In one embodiment, a ferrule assembly includes a ferrule body and a fiber array ferrule. The ferrule body includes a first end face and a second end face, at least one cavity for receiving one or more optical fibers disposed between the first end face and the second end face, and at least one body alignment component at an outer surface of the body. The fiber array ferrule includes a first end face and a second end face, an array of alignment holes extending between the first end face and the second end face, and at least one ferrule alignment component at an outer perimeter of the fiber array ferrule. The second end face of the fiber array ferrule is coupled to the first end face of the body.

Description

[0001] related application [0002] This application claims the benefit of priority to US Application No. 16 / 778,020, filed January 31, 2020, the contents of which are relied upon and incorporated herein by reference in their entirety. technical field [0003] The present disclosure relates generally to optical connections, and more particularly to ferrule assemblies having lens arrays and alignment features fabricated by laser processes. Background technique [0004] Advantages of optical communication include extremely wide bandwidth and low noise operation. Because of these advantages, optical fibers are increasingly being used for a variety of applications including, but not limited to, broadband voice, video, and data transmission. Connectors are commonly used in data centers and telecommunications systems to provide service connections to rack-mounted equipment and to provide inter-rack connections. [0005] Optical interconnects in data centers use cables containing...
