Abstract:
A device comprising:a first one channel sub-assembly having a first small format optical subassembly, a first optical coupling element, and a first substrate, the first optical coupling element having a first ferrule receiving bore and a first focusing element, the first small format optical subassembly attached to the first optical coupling element and to the first substrate; and a second one channel sub-assembly having a second small format optical subassembly, a second optical coupling element, and a second substrate, the second optical coupling element having a second ferrule receiving bore and a second focusing element, the second small format optical subassembly attached to the second optical coupling element and to the second substrate, and wherein â€ƒthe second small format optical subassembly is positioned between the second substrate and the second focusing element, and wherein the second small format optical subassembly is associated with only one optical coupling element, and wherein â€ƒthe second optical coupling element is associated with only one small format optical subassembly, and wherein the second optical coupling element has only one ferrule receiving bore and only one focusing element, and wherein â€ƒthe second small format optical subassembly is positioned relative to the second substrate only along an edge of the second substrate, and wherein the first ferrule receiving bore is parallel to the second ferrule receiving bore, and wherein â€ƒthe first ferrule receiving bore is separated from the second ferrule receiving bore by a first distance.
