Abstract

An optocasule unit for an optohybrid assembly (10), said capsule unit comprising a lower casing part (36) and a compatible upper cover part (54) which together form, at one end (50) thereof, an integral receptacle section for obtaining an optomechanical interface and receiving and detachably holding therein an optical connector with at least one external optical fiber. A central section (38) of the lower casing part (36) has a cavity (42) for receiving, in a form-closed manner, a ferrule (12) of the optohybrid assembly (10). The lower casing part (36) has, at a second end thereof, a base plate (44) for supporting a substrate (20) having at least one optochip (26, 28) and a proximal end of at least one primary optical fiber (22, 24) mounted thereon. The cover part (54) also has a section (58) covering the substrate (20) and at least a portion of the base plate (44) of the lower part. The invention is also addressed to the lower casing part (36) of the optocapsule unit for enclosing an optohybrid assembly (10) therein, and to an optoelectronic module (62) comprising the capsule unit with an optohybrid assembly enclosed therein.
