  • Patent number: 7630127
    Abstract: A bidirectional amplification system and method are disclosed. A single optical line amplifier and isolation loss filters are used to amplify signals in both the east and west directions with sufficient gain along a fiber. In an embodiment, a first signal propagating in a first direction (e.g., east) from a first port and second signal propagating in a second direction (e.g., west) from a second port are received at an optical amplifier module. The first and second signals are combined into a combined signal propagating in one direction. The combined signal is then amplified. The combined signal is then split into amplified first and amplified second signals. The isolation loss of each amplified signal is increased. Then, the amplified first signal propagating in the first direction is output at the second port and the amplified second signal propagating in the second direction is output at the first port.
