Power feed arrangement using aggregate segments
View Patent ↗A power feed arrangement for aggregate segments of a communications system is disclosed. In embodiments of the invention, cables are used to communicatively connect a number of landmasses, where the cables also serve to carry electrical power to devices connected along lengths of the cables. A first cable is connected to first and second landmasses, while a second cable is connected to second and third landmasses. On the second landmass, the electrical power conductors of the first and second cables are electrically connected to one another, and pieces of power feed equipment located on said first and third landmasses are used to supply electrical power to devices located along lengths of the first and second cables. Alternative embodiments are also disclosed.
1. A method of expanding a communication system comprising the acts of:
locating an existing communication system including:
a first and a second landmass having a first and a second piece of power feed equipment, respectively;
a first underwater cable carrying signals between said first and said second landmass, wherein said first underwater cable includes a first electrical power conductor having a first and a second end electrically connected to said first and said second piece of power feed equipment, respectively; and
a first repeater electrically connected to said first electrical power conductor;
laying a second underwater cable carrying signals between said second landmass and a third landmass wherein said first, said second, and said third landmasses are separated by at least one body of water, said second underwater cable including a second electrical power conductor and a second repeater electrically connected to said second electrical power conductor;
providing a third piece of electrical power feed equipment located on said third landmass;
electrically connecting a first end of said second electrical power conductor to said third piece of power feed equipment;
making a permanent electrical connection on said second landmass between second end of said first electrical power conductor and a second end of said second electrical power conductor;
eliminating said second piece of power feed equipment from said communication system such that said first and said second repeater are powered exclusively by said first and said third pieces of power feed equipment; and
increasing an electrical power provided by said first piece of power feed equipment in response to said act of eliminating said second piece of power feed equipment from said communication system.
2. The method of claim 1 , further comprising the step of relocating the second piece of power feed equipment from the second landmass to the third landmass, wherein said second and said third pieces of power feed equipment are the same.
3. The method of claim 1 , wherein said first underwater cable is communicatively coupled for carrying one or more data signals to a first communication network located on the first landmass from a second communication network located on either said second or said third landmasses.
4. A method of expanding a communication system comprising the acts of:
laying a first underwater cable carrying signals between a first and a second landmass, wherein said first underwater cable includes a first electrical power conductor;
electrically connecting a first end of said first electrical conductor to a first piece of power feed equipment located on said first landmass;
electrically connecting a first repeater to said first electrical power conductor;
disconnecting a second end of said first electrical conductor from a second piece of electrical power feed equipment located on said second landmass;
relocating said second piece of electrical power feed equipment from said second landmass to said a third landmass, wherein said first, said second, and said third landmasses are separated by at least one body of water;
laying a second underwater cable carrying signals between said second landmass and said third landmass, said second underwater cable including a second electrical power conductor;
electrically connecting a first end of said second electrical power conductor to said second piece of electrical power feed equipment located on said third landmass;
electrically connecting a second repeater to said second electrical power conductor;
making a permanent electrical connection on said second landmass between said second end of said first electrical power conductor and a second end of said second electrical power conductor; and
increasing an electrical power provided by at least one of said first and said second pieces of power feed equipment in response to said act of relocating said second piece of power feed equipment from said second landmass to said third landmass, wherein said first and said second repeaters are powered exclusively by said first and said second pieces of power feed equipment.
5. The method of claim 4 , wherein said first underwater cable is communicatively coupled for carrying one or more data signals to a first communication network located on the first landmass from a second communication network located on either said second or said third landmasses.
