Abstract
An optical signal transceiver in a transistor outline package includes a component base, a laser device, a first wavelength division multiplexing prism and a second wavelength division multiplexing prism, a first photodetector, and a second photodetector. The component base is inside the transistor outline package and supports the laser device, the laser device emitting light to the outside of the transistor outline package. The first and second prisms and the first photodetector and the second photodetector are also located on the component base. Light output as optical signals sequentially pass through the first and second multiplexing prisms. The first input optical signal is transmitted to the first photodetector through the first prism, and the second input optical signal passes through the first prism and is passed on to the second photodetector via the second prism.
