Fiber optic module assemblies and connector assemblies using the same

摘要

Fiber optic module assemblies and optical-electrical connectors incorporating the same are disclosed. The fiber optic module assembly generally includes a total-internal-reflection (“TIR”) module having TIR body including a TIR surface to direct light to active optical components. The TIR body is coupled to a lens module including a lens body having a plurality of lens surfaces. A plurality of optical fibers may be secured within fiber support features of the TIR body that aligns ends of the optical fibers to the lenses defined by the lens body. Alignment features and index-matching adhesive may be used to couple the TIR body to the lens body. Optical-electrical connectors employing such two-piece fiber optic module assemblies are also disclosed, as well as kits of parts for providing optical communication of light between an active optical component and an optical fiber.

主权项

1. A fiber optic module assembly comprising:
a total-internal-reflection (TIR) module having a TIR body that is transmissive to light having a predetermined wavelength, the TIR body comprising:
a first surface and a second surface that is opposite from the first surface; anda TIR surface extending from the first surface, wherein the TIR surface is operable to reflect an optical signal of light propagating within the TIR body by total internal reflection; and a lens module having a lens body that is transmissive to light having the predetermined wavelength, the lens body comprising:
a first surface and a second surface that is opposite from the first surface, wherein the second surface of the TIR body is coupled to the first surface of the lens body; anda plurality of lens surfaces formed on the second surface of the lens body, wherein:
at least the plurality of lens surfaces and the TIR surface define a plurality of lenses, each lens having a folded optical axis;the plurality of lens surfaces comprises one or more first lens surfaces and one or more second lens surfaces; andthe one or more first lens surfaces are offset with respect to the one or more second lens surfaces in a direction that is orthogonal to the first surface of the lens body.
