Abstract: An optical communications adapter module is provided which includes a casing of a XENPAK-sized module and an optical communications board assembly positioned within the casing. The module also includes a first optical connector coupled to a second optical connector by fiber optics capable of communicating data between the first optical connector and the second optical connector where the first optical connector is coupled to a data transmission connector of the optical communications board assembly and the second optical connector is positioned at a face plate of the casing. The module also includes a third optical connector coupled to a fourth optical connector through fiber optics capable of transmitting data where the third optical connector is coupled to a data reception connector of the optical communications board assembly and the fourth optical connector is positioned at the face plate of the casing.
