Patent ID: 7362931

Claim:
An optical conversion device for interfacing first and second optical fibers of a shared FTTH distribution network, comprising: an optical processing circuit, having a first input for receiving a first optical analog signal carried by said first optical fiber and an output for providing a first optical digital signal for transmission via said second optical fiber, wherein said optical processing circuit is configured to digitize said first optical analog signal and incorporate into said first optical digital signal; a first optical splitter having an input/output (I/O) for coupling to said first optical fiber, an input for receiving and passing a first forward optical signal carried by said second optical fiber to said first optical fiber, and a first output coupled to said first input of said optical processing circuit for passing said first optical analog signal; and a second optical splitter having an I/O for coupling to said second optical fiber, an output for passing said first forward optical signal, and an input coupled to said output of said optical processing circuit for receiving and providing said first optical digital signal to said second optical fiber.
