Abstract:
An optical network formed by at least two optical nodes for transferring optical signals along said optical network, said network comprising:a first node comprising a first optical multiplexer configured to receive optical signals having at least a first wavelength, said optical multiplexer further configured to output optical signals having at least said first wavelength to at least a second node along said optical network and to route at least one incoming optical signal having said first wavelength modulated with incoming user information to an optical transceiver; and said optical transceiver coupled to said first optical multiplexer and configured to receive said at least one incoming optical signal and to output at least a portion of the light of said incoming optical signal to provide an outgoing optical signal; anda second node comprising a second optical multiplexer configured to receive at least said outgoing optical signal from said first node of said first wavelength and to route at least said received outgoing optical signal at said first wavelength to a second optical transceiver, said second optical transceiver coupled to said second optical multiplexer and configured to receive at least said received outgoing optical signal and to output at least a portion of the light of said received outgoing optical signal of said first wavelength to said second optical multiplexer to provide a second outgoing optical signal at said first wavelength along said optical network.
