Low-profile optical communications module having two generally flat optical connector modules that slidingly engage one another

A low-profile optical communications module is provided that has two generally flat optical connector modules that slidingly engage one another to allow optical signals to be coupled between the optical connector modules. Because of the generally flat shapes of the optical connector modules and the manner in which they slidingly engage on another, the optical communications module has a very low profile that makes it well suited for use in thin devices, such as laptop and notebook computers and other electronics devices.
