OPTICAL SUB-ASSEMBLY AND PACKAGING METHOD THEREOF

摘要

The present invention discloses an optical sub-assembly (OSA) comprising: a base; at least one photoelectric component; and a housing. The base includes an alignment part including an upper surface and a side surface; the side surface includes a first surface and a second surface; and the first and second surfaces have different curvatures and/or constitute a discontinuous surface. Said photoelectric component is set upon the upper surface for optically connecting to a fiber. Said housing includes a window and an interior surface in which the window is for inserting the fiber, and the interior surface is for defining an accommodation room and includes a third surface and a fourth surface. The accommodation room is capable of containing at least some of the alignment part; meanwhile, the third surface closely meets the first surface and the fourth surface closely meets the second surface.

主权项

1. An optical sub-assembly comprising:
a base including an alignment part which includes:
an upper surface; anda side surface including a first surface and a second surface having different curvatures respectively or constituting a discontinuous surface together; at least one photoelectric component set upon or above the upper surface of the base for optically connecting to a fiber; and a housing including:
a window for inserting the fiber to carry out optical coupling with the at least one photoelectric component; andan interior surface defining an accommodation room and including a third surface and a fourth surface, wherein the accommodation room is capable of containing at least some of the alignment part and covering at least a part of the side surface while the third surface closely meets the first surface and the fourth surface closely meets the second surface.
