<P>PROBLEM TO BE SOLVED: To provide an optical transceiver which uses a small number of components and includes a structure that easily assembles a main substrate (first circuit board) to a sub substrate (second circuit board) through snap-in engagement. <P>SOLUTION: In an optical data link, optical sub assembly 1a, 1B, on which photoelectric conversion elements are respectively mounted, and a circuit board, on which a group of electronic circuit components are mounted, are housed and held in a housing composed of a base cover and a top cover. The circuit board is composed of a first circuit board 2 and a second circuit board 3. The first circuit board 2 and the second circuit board 3 are temporarily held on both upper and lower surface sides of a substrate holder 6, which are integrally molded with an insulative resin, through snap-in engagement. Then, the first circuit board 2 and the second circuit board 3 are positioned by the housing to be held and fixed thereto. <P>COPYRIGHT: (C)2012,JPO&INPIT |
