1Length of stationary object
If a repeater is used to extend transmission distance, then transmission distance is improved, but signal processing complexity increases due to decoding and encoding
Solution Approach 1:
The patent extracts and removes the complex decoding and encoding operations from the signal transmission path. Instead of fully decoding and re-encoding signals at repeater nodes, the system uses optical amplification to directly amplify optical signals, eliminating the need for complex electronic signal processing while extending transmission distance.
Solution Approach 2:
The patent replaces electronic signal processing mechanisms (decoding/encoding circuits) with optical amplification mechanisms. Optical amplifiers directly amplify optical signals without converting to electrical signals, substituting complex electronic processing with simpler optical domain operations, thereby reducing device complexity while maintaining extended transmission capability.
2Reliability
If decoding and encoding processes are implemented in repeater, then signal transmission is enabled, but transmission efficiency deteriorates
Solution Approach 1:
The patent implements continuous optical amplification along the transmission path rather than discrete decode-reencode operations. Optical amplifiers are placed at strategic points to continuously amplify the optical signal as it propagates, maintaining signal integrity without interrupting the continuous flow of data, thus improving transmission efficiency while ensuring reliability.
Solution Approach 2:
The patent skips the time-consuming decoding and encoding processes by directly amplifying optical signals in the optical domain. This allows the signal to rush through the transmission medium without being converted to electrical signals for processing, dramatically improving transmission efficiency while maintaining signal reliability through optical amplification.

AI summary
A communicating system suitable for a repeater and communicating method thereof are described. The communicating system comprises a receiving unit, a delay module, a transmitting unit and a control unit. The receiving unit transmits a first signal based on a KB/MS input signal. The delay module is coupled to the receiving unit and delays the first signal from the receiving unit in order to generate a second signal. The second signal has a first phase difference in comparison with the first signal. The transmitting unit is coupled to the delay module and the control unit. The transmitting unit transmits a KB/MS output signal based on the second signal while the control unit controls the transmitting unit via a control signal. Specifically, the control unit is coupled to the receiving unit, the delay module and the transmitting unit such that the control unit generates the control signal based on the first signal from the receiving unit and controls the transmitting unit by inputting the control signal into the transmitting unit. That is, the control signal of the control unit triggers the transmitting unit to dominate output control of the delayed second signal of transmitting unit. The control signal generated by the control unit has a second phase difference in comparison with the first signal.
