Abstract:
1. A method for mitigating the effects of interference on video information from data signals comprising the steps of: receiving input from a routing device; determining whether the input comprises data and if the input comprises data, then converting the data from an electrical domain to a digital optical domain; determining whether the input comprises one of an absence of data and an idle pattern; generating substitute data in an electrical domain 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; in response to detecting one of an absence of data and an idle pattern, converting the substitute data from the electrical domain to the digital optical domain 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 along with video information in an analog optical domain through a single optical waveguide, the substitute data in the digital optical domain comprising minimal concentration of optical power for reducing any optical interference between the substitute data and the video information caused by physical properties of the single optical waveguide combined with selected optical wavelengths and optical power of the substitute data and video information.
