Abstract: A bidirectional optical sub assembly includes a base made of a conducting material, and the base has a first part and a second part. An input port transmits a first electrical signal to a transmitter, the transmitter converts the first electrical signal into a first optical signal, and transmits the first optical signal to a wavelength division multiplexing element. A wavelength division multiplexing element reflects an optical signal of a first wavelength, or transmits an optical signal of a second wavelength different from the first wavelength. The wavelength division multiplexing element reflects the first optical signal, and transmits a second optical signal to a receiver. The receiver converts the second optical signal into a second electrical signal, and outputs the second electrical signal using an output port. An isolation element electromagnetically isolates the receiver from the transmitter.
