A method for coding three-dimensional (3D) data, and more particularly for coding geometry data included in the 3D data. The method includes: generating a bounding box including a vertex of the 3D data based on information included in the geometry data; dividing the bounding box into a plurality of partitions having an equal size; identifying a number of vertices included in each divided partition; appointing a divided partition as a leaf cell based on the identified number of vertices; and coding the geometry data using information on the dividing of the bounding box, information on vertices included in each divided partition, and information indicating the position of a vertex included in the leaf cell, when a divided partition is subdivided.

A high-speed optical modulator module which includes: a lead frame having an outer lead frame and an inner lead frame, the outer lead frame for receiving a high-speed signal; a substrate, in which a metal base having a matching impedance device, and a submount having a laser diode thereon, are formed; a first multi-bonding wire for electrically connecting the inner lead frame of the lead frame to one end of the matching impedance device; a second multi-bonding wire for electrically connecting the other end of the matching impedance device to one end of the metal base; and a dual-bonding wire for electrically connecting the other end of the metal base to the laser diode. The matching impedance device includes a matching resistor and a compensation capacitor connected in parallel. The module is formed by packaging and sealing the components other than the outer lead frame.
