摘要： An optical subassembly includes: a conductor plate having a pair of penetration holes, both penetrating the conductor plate from an outer surface to an inner surface; a pair of lead terminals fixed in the two respective penetration holes and passing through the pair of penetration holes; a wiring board with a pair of wiring patterns arranged on a surface; and a plurality of bonding wires electrically connecting the pair of lead terminals and the pair of wiring patterns. A cross section of the pair of lead terminals on the inner surface side is larger than a cross section on the outer surface side. End faces on the inner surface side are situated within a range from +180 μm to −100 μm to the inner side from the inner surface of the conductor plate in a direction perpendicular to the inner surface.

摘要： The second wiring pattern includes extended regions from the main body side to the projecting portions as seen in a direction in which the pair of leads extend, and wiring regions continuously spreading from the extended regions in a direction away from the main body. Supposing that a length of the wiring region from an end of the projecting portion as a reference point to a farthest position in a direction away from the main body is a first width and a width of the extended region in a direction parallel to a side opposed to the main body side through the end of the projecting portion is a second width, the first width is smaller than the second width. The second insulating substrate is sandwiched between the second wiring pattern and a base, and thereby, a capacitance is formed.

摘要： A plurality of leads include a pair of differential signal leads for inputting differential signals, and a power supply lead for supplying power. A wiring pattern includes a pair of differential transmission lines connected to the pair of differential signal leads, and a power supply wiring connected to the power supply lead. A wiring board includes a first region overlapping an optical subassembly, and a second region extending from the first region so as to protrude from the optical subassembly. The pair of differential signal leads are farther away from the second region than the power supply lead. The pair of differential transmission lines are close together so as to be electromagnetically coupled to each other. The optical subassembly does not include a lead penetrating the wiring board in a region between the pair of differential transmission lines.
