  • Optical communication system, optical transmitter module, and optical receiver module
    Patent number: 10862587
    Abstract: An optical transmitter module includes: a low-speed light emitting device that emits an optical signal at a first given wavelength; a high-speed light emitting device that emits an optical signal at a second given wavelength; and a first filter that transmits one and reflect the other of the first- and second-given-wavelength optical signals to send the optical signal to an optical receiver module. The optical receiver module includes: a low-speed light receiving device that receives the optical signal at the first given wavelength; a high-speed light receiving device that receives the optical signal at the second given wavelength; and a second filter that transmits one and reflects the other of the first- and second-given-wavelength optical signals to send the first-given-wavelength optical signal to the low-speed light receiving device, and the second-given-wavelength optical signal to the high-speed light receiving device.

  • Communication system
    Patent number: 9654214
    Abstract: A communication system is capable of determining, at a reception side of a communication circuit, whether a communication method connected is of optical communication or electric communication. When the communication system is activated, a communication circuit transmission unit transmits a differential high fixed output. When a communication circuit reception unit receives a differential high fixed signal, it is determined that electric communication is used. When the communication circuit reception unit receives a differential low fixed signal, it is determined that optical communication is used.
