Patent ID: 7329052

Claim:
A method, comprising: securing terminals of one or more optical fibers exiting an end surface of at least one optical ferrule to a first substrate to form an optical subassembly; providing a second substrate having a main surface and at least one groove extending inward from the main surface; after forming the optical subassembly, securing the optical subassembly to the second substrate such that the at least one optical ferrule is at least partially received into the at least one groove of the second substrate, the first substrate is placed on the main surface of the second substrate, and the first substrate is between the one or more optical fibers and the second substrate; wherein: the at least one optical ferrule has a main body and at least one securing portion extending from the main body, the at least one groove has a first main portion adapted to receive at least a portion of the main body and at least one second portion adapted to receive at least a portion of the at least one securing portion; and the optical subassembly is secured to the second substrate such that a portion of the at least one securing portion is received into the at least one second portion.
