摘要： A method for overlapping spectrum amplification includes receiving an optical signal and splitting the optical signal into a first split signal having a first wavelength band and a second split signal having a second wavelength band. The splitting results in a band gap between the first wavelength band and the second wavelength band. The method further includes delaying the first split signal by a threshold period of time relative to the second split signal and combining the first split signal and the second split signal, resulting in a combined signal having the first wavelength band and the second wavelength band without the band gap therebetween. The path difference between the first split signal along the first signal path and the second split signal along the second signal path is within a threshold multipath interference compensation range.

摘要： A branching unit for an optical system includes an optical add-drop multiplexer, which includes first and second filters. The first filter is configured to filter a first band of wavelengths of a communication spectrum for a first communication segment. The second filter is configured to filter a second band of wavelengths of the communication spectrum for a second communication segment. The second band of wavelengths overlaps the first band of wavelengths in an overlap band of wavelengths with no guard band between the first band of wavelengths and the second band of wavelengths. Moreover, the overlap band of wavelengths has a variable size. The first band of wavelengths includes a first fraction of the overlap band of wavelengths for the first communication segment and the second band of wavelengths includes a remaining fraction of the overlap band of wavelengths for the second communication segment.

摘要： An optical system for a locally powered optical communication network includes a first trunk terminal emitting an optical signal, a second trunk terminal receiving the optical signal, a communication trunk, an intermediate unit and a power source. The communication trunk is disposed along a floor of a body of water and couples the first trunk terminal to the second trunk terminal. The communication trunk transmits the optical signal from the first trunk terminal to the second trunk terminal. The intermediate unit is connected to the communication trunk between the first and second trunk terminals. The intermediate unit receives the emitted optical signal from the first trunk terminal, amplifies the received optical signal and sends the amplified optical signal to the second trunk. The power source is connected to and powers the intermediate unit and is located at or near a surface of the body of water.

摘要： A communication system includes a first and second trunk terminals, a plurality of communication trunks disposed along a floor of a body of water, and power feed equipment. Each communication trunk couples the first trunk terminal to the second trunk terminal and includes at least one signal amplifier configured to amplify a signal conveyed along the corresponding communication trunk. The power feed equipment is coupled to the plurality of communication trunks and is configured to deliver power along each communication trunk to power the at least one signal amplifier of the communication trunk. The power feed equipment is also configured to receive a shunt fault notification identifying an electrical shunt fault along a faulted communication trunk of the plurality of communication trunks. In response to the shunt fault notification, the power feed equipment is configured to cease delivery of power along at least one communication trunk.
