Abstract
An optical network element for a hardware configured optical network includes a first optical port that receives an input optical signal comprising receive control information from the hardware configured optical network. A demodulator optically coupled to the first optical port decodes the receive control information for configuring the optical network element. A modulator having an electrical modulation input that receives transmit control information imparts a modulation onto an optical carrier thereby generating a transmit optical control signal representing the transmit control information. A second optical port transmits the transmit optical control signal representing the transmit control information to the hardware configured optical network.
Claims20
An optical transceiver comprising:
- a tunable optical transmitter having an optical output configured to generate an output optical signal having a wavelength that is adjustable across a wavelength range, the output optical signal comprising output client data traffic and output control information that is encoded onto a low-frequency output control signal imposed directly onto the output optical signal;
- an optical receiver having an input that is optically coupled to an optical input port, the optical input port being configured to receive an input optical signal emerging from a remote optical transceiver that includes input client data traffic and input control information that is encoded onto a low-frequency input control signal imposed directly onto the input optical signal,
- high-pass filtering used to filter the input client data traffic or the output client data traffic;
- and
- a processor having an input that is electrically coupled to an output of the optical receiver, the processor being configured to decode the received input control information to obtain configuration information from the remote optical transceiver,
- wherein a frequency of the low-frequency input control signal is below a lowest frequency of a low-frequency cut-off of the high-pass filtering.
A method of configuring an optical transceiver, the method comprising:
- generating an output optical signal comprising output client data traffic with a tunable optical transmitter;
- encoding output control information onto a low-frequency output control signal and imposing the low-frequency output control signal directly onto the output optical signal;
- receiving an input optical signal from a remote optical transceiver, the input optical signal including input client data traffic and input control information that is encoded onto a low-frequency input control signal imposed directly onto the input optical signal;
- and
- filtering the input client data traffic or the output client data traffic using a high-pass filter, wherein a frequency of the low-frequency input control signal is below a lowest frequency of a low-frequency cut-off of the high-pass filter.
