Claim:
An apparatus, comprising: a first substrate; at least one optical ferrule with terminals of one or more optical fibers exiting an end surface of each optical ferrule secured to the first substrate to form an optical subassembly; a second substrate including a main surface and at least one groove extending inward from the main surface; the optical subassembly being secured to the second substrate such that the at least one optical ferrule is at least partially received in the at least one groove of the second substrate and that the first substrate is between the one or more optical fibers and the second substrate, and such that the at least one groove restrains at least a portion of the at least one optical ferrule, wherein: the at least one optical ferrule includes a main body and at least one securing portion extending from the main body; the at least one groove includes a first main portion and at least one second portion; the main body of the at least one optical ferrule is at least partially received in the first main portion of the at least one groove; and at least one portion of the at least one securing portion of the at least optical ferrule is at least partially received in the at least one second portion of the at least one groove.
