Abstract: The present invention discloses an optical connector comprising a first connector and a second connector. The first connector includes: a first space to accommodate a first fiber joint and a part of a first optical transmission line; a first front opening to expose a first signal transmission interface of the first fiber joint; a first rear opening through which the first optical transmission line connects with the first fiber joint; and a first fastening. The second connector includes: a second space to accommodate a second fiber joint and a part of a second optical transmission line; a second front opening to expose a second signal transmission interface of the second fiber joint; a second rear opening through which the second optical transmission line connects with the second fiber joint; and a second fastening to be fixed to the first fastening in a nondestructive detachable way.

Abstract: 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.
