ABSTRACT:
An optical communication system includes a first wavelength filter, a bidirectional amplifier, and a second wavelength filter. The first wavelength filter can receive a downstream broad-spectrum signal and output a downstream spectrum-sliced signal in response to the downstream broad-spectrum signal. The bidirectional amplifier can amplify the downstream spectrum-sliced signal. The second wavelength filter can receive the amplified downstream spectrum-sliced signal from the bidirectional amplifier and route the amplified downstream spectrum-sliced signal. The second wavelength filter can also output an upstream spectrum-sliced signal in response to an upstream broad-spectrum signal. The bidirectional amplifier can amplify the upstream spectrum-sliced signal to product an amplified upstream spectrum-sliced signal that is subsequently routed by the first wavelength filter.
