OPTICAL COMMUNICATION APPARATUS, OPTICAL COMMUNICATION SYSTEM AND OPTICAL COMMUNICATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18033549 titled 'OPTICAL COMMUNICATION APPARATUS, OPTICAL COMMUNICATION SYSTEM AND OPTICAL COMMUNICATION METHOD

Simplified Explanation

The abstract describes an optical communication device that includes an optical switch, a wavelength management control unit, and an optical switch control unit.

  • The optical switch is responsible for routing optical signals from one transmission line to another among a plurality of transmission lines.
  • The wavelength management control unit allocates various parameters such as wavelength, time, polarized wave, mode, code, frequency, core, core wire, or a combination thereof to a subscriber device based on a control signal. This control signal is transmitted to the subscriber device using a different carrier than the allocated wavelength.
  • The optical switch control unit controls the optical switch to ensure that the input optical signal is directed to the appropriate transmission line corresponding to the communication destination.

Potential applications of this technology:

  • Optical communication networks: This device can be used in optical communication networks to efficiently route optical signals between different transmission lines.
  • Fiber optic systems: It can be utilized in fiber optic systems to manage and allocate different parameters to subscriber devices.
  • Telecommunications: The device can enhance the performance and flexibility of telecommunications systems by providing efficient routing and allocation of optical signals.

Problems solved by this technology:

  • Efficient signal routing: The optical switch allows for the seamless transfer of optical signals between different transmission lines, improving the efficiency of communication networks.
  • Parameter allocation: The wavelength management control unit enables the allocation of various parameters to subscriber devices, ensuring optimal performance and customization.
  • Control signal transmission: By using a different carrier for transmitting the control signal, potential interference with the allocated wavelength or other parameters is minimized.

Benefits of this technology:

  • Improved network efficiency: The optical switch and control units optimize the routing and allocation of optical signals, leading to improved network efficiency and performance.
  • Customization and flexibility: The ability to allocate various parameters to subscriber devices allows for customization and flexibility in optical communication systems.
  • Reduced interference: The use of a separate carrier for control signal transmission minimizes potential interference with the allocated wavelength or other parameters, ensuring reliable communication.


Original Abstract Submitted

An optical communication device include: an optical switch configured to output an optical signal input from one transmission line to another transmission line among the plurality of transmission lines; a wavelength management control unit configured to allocate a wavelength, a time, a polarized wave, a mode, a code, a frequency, a core, a core wire, a wavelength that is a combination thereof, or the like to a subscriber device by using a control signal in accordance with the subscriber device and a transfer destination on a path to a communication destination, and transmits the control signal to the subscriber device by using a carrier different from a carrier to which the wavelength or the like is allocated; and an optical switch control unit configured to control the optical switch such that the input optical signal is output to the another transmission line corresponding to the communication destination.
