  • Hardened, wavelength enabled optical capacity
    Patent number: 8116631
    Abstract: Providing bandwidth expansion in existing HFC infrastructures. A break in a fiber ring is established. A temperature hardened demultiplexer is coupled at the break to an input side of the fiber ring. A temperature hardened multiplexer is coupled at the break to an output side of the fiber ring. The temperature hardened demultiplexer is configured to pass-through a first predetermined wavelength to the temperature hardened multiplexer and to drop out a second predetermined wavelength. The second predetermined wavelength is extended from the demultiplexer for providing a first predetermined wavelength to an expansion node. The temperature hardened multiplexer is configured to receive the first predetermined wavelength from the temperature hardened demultiplexer and to receive the second predetermined wavelength from the expansion node.
    Type: Grant
