A plastic encapsulated optomodule is provided which includes a leadframe, an optoelectric component, an electric component, and an optical connection interface integrated in the capsule. The electric component is connected electrically to the leadframe. The electric component and the optoelectric component are mutually connected electrically and the optoelectric component and the integrated connection interface are connected together via at least one optical waveguide. The electric component is provided on a first part of the leadframe and electric contact surfaces ( ) are provided on leads ( and ) in the leadframe ( ). The optoelectric component is provided on a second part of the leadframe and the optical connection interface arranged on an optodevice is connected to a third part of the leadframe. The optodevice is aligned by alignment elements provided on the leadframe and the leadframe includes alignment elements that conform with corresponding alignment elements on a plastic-encapsulation mold tool.

The present invention relates to a mold for simultaneously molding a plurality of ferrules onto a corresponding number of optical fibers. The mold preferably includes a runner plate, a first cavity plate, a second cavity plate, and a support plate, each of which is to be inserted between a movable top plate and a fixed bottom plate of a transfer molding machine. The plates to be inserted have a vertical inlet channel and primary and secondary runners for distributing molding compound. These runners lead to a plurality of first and second mutually coincidental mold cavities arranged in rows in the first and second cavity plates, respectively. In a preferred embodiment, each of the first and second mold cavities are made up of mutually coincidental, cylindrical coaxial parts and a larger coaxial, cylindrical bore formed in one or both cavity plates. The dividing plane between the first and second cavity plates coincides with the wider bore. The second mold cavity is formed in a conical insert which is inserted into the second cavity plate. The support plate includes narrow optical fiber receiving slots.
