Abstract:
1. A method for mitigating the effects of optical interference from optical data signals comprising the steps of: receiving electrical input with a detector; determining whether the electrical input comprises data with the detector and if the electrical input comprises data, then converting the data from an electrical domain to a digital optical domain with an optical transmitter; determining whether the input comprises one of an absence of data and an idle pattern with the detector; if the input comprises one of an absence of data and an idle pattern, generating substitute data in an electrical domain with a replacement data device that reduces power at one or more harmonics in the electrical domain such that a concentration of power in the digital optical domain is minimized when the substitute data is converted into the digital optical domain; maintaining power to the optical transmitter during an absence of data or after receiving an idle pattern; in response to detecting one of an absence of data and an idle pattern with the detector, converting the substitute data from the electrical domain to the digital optical domain with the optical transmitter so that data transmission in the digital optical domain is substantially continuous when the input comprises one of an absence of data and an idle pattern; and propagating the substitute data in the digital optical domain.
