SEALED ASSEMBLY FOR OPTICAL FIBER ALIGNMENT Russian patent published in 2018 - IPC G02B6/36 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to clutch designs for an optical fiber, in particular to a sealed assembly (assemblies) for aligning the optical fiber comprising a clutch for aligning the optical fibers. Sealed optical fiber alignment assembly includes the first clutch part having the first surface provided with a plurality of grooves accommodating the end portions of the optical fibers, wherein the grooves define the position and orientation of the end portions relative to the first part of the clutch, and the second clutch part having the second surface facing the first surface of the first clutch part, wherein the first clutch part is connected to the second clutch part in such a way, that the first surface faces the second surface where a cavity is defined between the first part of the clutch and the second part of the clutch, where the cavity is wider than the grooves, and where the suspended portion of each optical fiber is suspended in the cavity and where the cavity is sealed with a sealant. Sealant covers the portions of the optical fibers suspended inside the cavity. Opening is created on at least one of the two parts of the clutch, either the first or the second one, to open the cavity where the sealant is fed through the opening. Also, in this sealed assembly the grooves extend in such a manner that they terminate at the first outer end of the first part of the clutch, so that the end portions of the optical fibers are held by the grooves in such a way, that the end of each optical fiber is open where the grooves are ended at the first end. According to another aspect, the sealed assembly provides optical alignment and an airtight passage for the optoelectronic module. In yet another aspect the sealed assembly provides alignment and a terminal device for accessing the optoelectronic module.

EFFECT: technical result of the invention is to improve the hermetically sealed alignment assembly for the optical fiber, as well as to improve the optical alignment.
