The present invention relates to an optical fiber interface and a method for making the same. A Thermal Conduction Module or TCM (10), comprises a lower frame (12), an upper frame (16), sandwiching a seal frame (14), are held together by bolts (18). Usually a cold plate (17), having a number of coolant channels (21), is secured to the upper surface of the upper frame (16), A substrate (40), having stepped edge (42), and having semiconductor chips (50), thereon, is secured between the ledge (41), of the lower frame (12), and the extension of seal frame (14), with a gasket (46), therebetween. Heat exchange elements (52) transfer the heat generated by the chips (50), to the upper frame (16). A retainer (51), holds the heat exchange elements (52), in place, and is also used to provide the guide grooves and securing means for an optical fiber (23). Cooling devices where there is no retainer, can be modified to provide means for guiding and securing the optical fiber (23), from the exterior of the TCM (10) , to an optoelectronic device on the substrate (40). A fluid tight seal for the chips (50), that are on the substrate 40, is achieved by means of gaskets (46, 48). An optical fiber mounting assembly (20), provides the interface between the multi-fiber optical cable (25), and the TCM (10). Face plate (22), keeper (32), wave washer (31), retainer (30), and shoulder (28), are various components of the optical fiber mounting assembly (20), that normally protrude out of the TCM (10). The optical fiber mounting assembly (20), may be located between any adjacent pair of bolts (18), along the sides of the TCM (10). Therefore, any side of the TCM (10), may then accommodate (N-1) optical fiber mounting assemblies (20), where N = number of bolts along the given side of the TCM (10). Each optical fiber mounting assembly (20), can have a multi-fiber optical cable (25), having one or more optical fibers (23) having a core of a first refractive index material with a cladding of a second refractive index material and a protective jacket which is typically of a polymeric material. <IMAGE> |
