Abstract: An optical transceiver module includes a housing having an electrical mating end for mating with a mating electrical connector and an opposing optical mating end for mating with a mating optical connector. A circuit board assembly, a ferrule assembly, and a first support are disposed in the housing. The circuit board assembly includes an optical coupler disposed on a circuit board. The ferrule assembly includes an optical ferrule including a first attachment feature for receiving and permanently attaching to at least one optical fiber and a second attachment feature assembled to the optical coupler. A ferrule support is removably assembled to an interior of the housing and includes at least one support feature. The optical ferrule rests on the at least one support feature. The first support makes contact with the at least one optical fiber. The contact causes a bend in the at least one optical fiber.

Abstract: An optical connector assembly (100) includes a housing (110), an optical ferrule (140); and an optical fiber array (150). The housing (110) has a mating end (111) and an opposite cable end (112) and includes: a first housing portion (120) including a front support (122) proximate the mating end (111) and a rear support (124) disposed between the front support (122) and the cable end (112); and a second housing portion (130) assembled to the first housing portion (120) and including a middle support (133) disposed between the front and rear supports (122,124). The ferrule (140) is supported by the front support (122). Front ends of optical fibers of the optical fiber array (150) are received by and attached to an attachment area of the ferrule (140). When the second housing portion (130) is assembled to the first housing portion (120), the middle support (133) of the second housing portion (130) contacts and bends the optical fiber array (150) about the middle support (133). The bend causes the optical ferrule (140) to rotate about the front support (122).
