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.
