Abstract: An optical transmitting/receiving apparatus capable of suppressing electrical crosstalk and magnetic crosstalk, includes: a laser diode/photo diode (LD/PD) integrated module that terminates a single-core bidirectional optical fiber; a circuit board electrically connected to a lead pin led out of the LD/PD integrated module; and a plastic case that accommodates the circuit board. At least a part of the plastic case abuts against the LD/PD integrated module, and impedance of the plastic case is controlled by mixing a conductive filler into the plastic case.

Abstract: An optical transceiver module is constituted so as to have an optical transmission module, an optical receiving module, a drive circuit board for driving the optical transmission module and the optical receiving module, and short-circuit means which induces an electrical short circuit between housings of the respective modules or induces an electrical short circuit between ground (GND) terminals of the respective modules on the module sides with respect to the drive circuit board. As a result, in the optical transceiver module, stray capacitance and stray inductance in lead pins, housings, and internal components of optical devices, such as an LD and a PD, are removed, thereby suppressing fluctuations in the potential (GND) of an LD housing which arise during high-frequency driving operation, as well as considerably suppressing electrical crosstalk between the transmission and receiving modules.
