Abstract
Operations include generating an optical signal having a plurality of subcarriers. The operations further include performing a signal-to-noise ratio (SNR) equalization process with respect to the plurality of subcarriers based on an SNR factor associated with propagation of the optical signal along an optical signal path, the SNR equalization process including respectively adjusting, for one or more individual subcarriers of the plurality of subcarriers, one or more of: a forward-error-correction rate respectively corresponding to the one or more individual subcarriers; or a symbol rate respectively corresponding to the one or more individual subcarriers.
Claims17
A system comprising:
- an optical transponder configured to perform operations, the operations including:
- generating an optical signal including a plurality of subcarriers;
- and
- performing a signal-to-noise ratio (SNR) equalization process with respect to the plurality of subcarriers based on an SNR factor associated with propagation of the optical signal along an optical signal path, the SNR equalization process including respectively adjusting, for one or more individual subcarriers of the plurality of subcarriers:
- a forward-error-correction (FEC) rate respectively corresponding to the one or more individual subcarriers;
- and
- a symbol rate respectively corresponding to the one or more individual subcarriers,
- wherein the symbol rate and the FEC rate are balanced to preserve a data rate for each individual subcarrier of the one or more individual subcarriers.
A method comprising:
- generating an optical signal including a plurality of subcarriers;
- and
- performing a signal-to-noise ratio (SNR) equalization process with respect to the plurality of subcarriers based on an SNR factor associated with propagation of the optical signal along an optical signal path, the SNR equalization process including respectively adjusting, for one or more individual subcarriers of the plurality of subcarriers:
- a forward-error-correction (FEC) rate respectively corresponding to the one or more individual subcarriers;
- and
- a symbol rate respectively corresponding to the one or more individual subcarriers,
- wherein the symbol rate and the FEC rate are balanced to preserve a data rate for each individual subcarrier of the one or more individual subcarriers.
A non-transitory computer-readable storage medium configured to store instruction that, in response to being executed, causes a system to perform operations, the operations comprising:
- generating an optical signal including a plurality of subcarriers;
- and
- performing a signal-to-noise ratio (SNR) equalization process with respect to the plurality of subcarriers based on an SNR factor associated with propagation of the optical signal along an optical signal path, the SNR equalization process including respectively adjusting, for one or more individual subcarriers of the plurality of subcarriers, one or more of:
- a forward-error-correction (FEC) rate respectively corresponding to the one or more individual subcarriers;
- and
- a symbol rate respectively corresponding to the one or more individual subcarriers,
- wherein the symbol rate and the FEC rate are balanced to preserve a data rate for each individual subcarrier of the one or more individual subcarriers.
