Patent ID: 7369728

Claim:
An apparatus comprising: an optical wave guide having a prespecified horizontal-positioning surface and a prespecified vertical-positioning surface; and, a ferrule to precisely couple with the optical wave guide, wherein the ferrule defines a first datum plane mating with the prespecified vertical-positioning surface of the optical wave guide to precisely mechanically vertically position the optical wave guide within the ferrule, wherein the ferrule defines a second datum plane mating with the prespecified horizontal-positioning surface of the optical wave guide to precisely mechanically horizontally position the optical wave guide within the ferrule, and wherein the ferrule has a top portion and a bottom portion, the top portion locking into the bottom portion, the optical wave guide disposed between the top portion and the bottom portion of the ferrule, the top portion having a width at least substantially equal to a width of the bottom portion, the top portion and the bottom portion of the ferrule being separate from one another and from the optical wave guide.
