TRANSMISSION APPARATUS AND TRANSMISSION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18170799 titled 'TRANSMISSION APPARATUS AND TRANSMISSION SYSTEM
Simplified Explanation
The patent application describes a transmission apparatus that is used to transmit an optical signal over a transmission line.
- The apparatus includes a signal power detector that detects the power of the optical signal.
- It also includes a variable optical attenuator that can adjust the power of the optical signal.
- The apparatus is controlled by a processor that determines the appropriate attenuation amount for the optical signal based on its power and the presence of a Raman amplifier.
- The Raman amplifier is a device that amplifies the optical signal by inputting pumping light into the transmission line.
- The processor adjusts the attenuation amount of the variable optical attenuator based on the signal power and the presence of the Raman amplifier to optimize the transmission of the optical signal.
Original Abstract Submitted
A transmission apparatus includes a signal power detector configured to detect signal power of a wavelength-multiplexed optical signal to be transmitted to a transmission line, a variable optical attenuator configured to attenuate the wavelength-multiplexed optical signal, and a processor configured to control an attenuation amount of the variable optical attenuator according to the signal power and whether a Raman amplifier in which pumping light is inputted to the transmission line exists.
