Abstract
A signal intensity flattening method includes: classifying a plurality of user devices accommodated in the same relay node so that user devices with similar optical signal intensities are in the same class; and setting a signal transmission path for converging optical signals transmitted from user devices of the same class in the same optical transmission line, and adjusting the signal intensities of the optical signals converged in the same optical transmission line collectively without separating them for each wavelength.

A signal intensity flattening method comprising:
- classifying a plurality of user devices accommodated in the same relay node so that user devices with similar optical signal intensities are in the same class;
- and
- setting a signal transmission path for converging optical signals transmitted from user devices of the same class in the same optical transmission line, and adjusting the signal intensities of the optical signals converged in the same optical transmission line collectively without separating them for each wavelength.
A relay node comprising:
- an allocator configured to classify a plurality of user devices accommodated therein so that user devices with similar optical signal intensities are in the same class, and sets a signal transmission path for converging optical signals transmitted from user devices of the same class in the same optical transmission line;
- and
- an adjuster configured to adjust the signal intensities of the optical signals converged in the same optical transmission line by the allocator collectively without separating them for each wavelength.
A signal intensity flattening method comprising:
- classifying a plurality of user devices accommodated in the same relay node into a minimum number of classes so that user devices with similar optical signal intensities are in the same class and a gain of a weak signal does not decrease due to gain saturation;
- and
- setting a signal transmission path for converging optical signals transmitted from user devices of the same class in the same optical transmission line, and converging optical signals transmitted from user devices of the same class in the same optical transmission line.
A relay node comprising:
- an allocator configured to classify a plurality of user devices accommodated in the same relay node into a minimum number of classes so that user devices with similar optical signal intensities are in the same class and a gain of a weak signal does not decrease due to gain saturation, sets a signal transmission path for converging optical signals transmitted from user devices of the same class in the same optical transmission line, and converges optical signals transmitted from user devices of the same class in the same optical transmission line.
