LOOP-BACK WAVELENGTH DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK |
摘要 |
Disclosed herein is a loop-back Wavelength Division Multiplexing Passive Optical network (WDM-PON). The loop-back WDM-PON includes a coupler, a terminal receiver, and a reflective semiconductor amplifier. The coupler branches a downstream signal, which is transmitted from a central office, into first and second downstream signals. The terminal receiver receives and converts the first downstream signal into electrical signal and provides the electrical signal to a subscriber. The reflective semiconductor optical amplifier flattens modulated optical power of the second downstream signal input to the RSOA and re-modulating the flattened signal by changing driving current in response to upstream data.
