Optical Transmission/Reception Equipment And Optical Transmission/Reception Module

摘要

The present invention provides a method for connecting an optical transmission/reception module and a circuit board in order to reduce electrical crosstalk effectively in single-fiber bidirectional optical transmission/reception equipment. The optical transmission/reception equipment includes an optical transmission/reception module which has at least one transmission subassembly with a built-in light-emitting device, one or a plurality of reception subassemblies each having a built-in light-receiving device, and a housing for fixing the transmission subassembly and the reception subassembly/subassemblies, and a circuit board on which an electronic device is mounted. At least one stem base part constituting a stem/stems of the reception subassembly/subassemblies and a stem base part constituting a stem of the transmission subassembly are directly connected to a ground pattern of the circuit board.
