Abstract:
1. An optical network, comprising: a first optical line termination device having a transceiver for sending an optical signal at a first wavelength and receiving an optical signal at a second wavelength, wherein the first wavelength and the second wavelength are different; an optical extender box comprising a first wavelength diplexer and a second wavelength diplexer, wherein the first wavelength diplexer and the second wavelength diplexer are both coupled to a first portion and a second portion, wherein the first portion is for transporting the first optical signal at the first wavelength and the second portion is for transporting the second optical signal at the second wavelength, wherein the first portion in an upstream direction comprises an upstream semiconductor amplifier, which is connected to an upstream isolator, which is connected to an upstream non-linear fiber, which is connected to an upstream pump laser, wherein the second portion in a downstream direction comprises a downstream semiconductor amplifier, which is connected to a downstream isolator, which is connected to a downstream non-linear fiber, which is connected to a downstream pump laser, wherein the optical extender box is coupled to the first optical line termination device via a first standard single mode fiber section; and an optical splitter coupled to the optical extender box via a second standard single mode fiber section.
