Abstract

The direction of this paper is to describe the experiments and analytical techniques used by SilkRoad, Inc. for sending 40 GHz of bandwidth, incorporating an eclectic body of data, over a single laser - single fiber over > 100Km of optical fiber using the same wavelength in both directions. The paper will outline the various basic tenets of Optical Refractive Synchronization and the subsequent use of Ellipsometric Phase, based on these tenets, that allows a compilation of CATV, voice, video and SONET data to be transported in both directions without interference between the otpical signals going in both directions over the single fiber. The second portion of the paper will describe the test setup and measurement techniques that were used to validate the analytical models. Pictures of the Spectrum Analyzer data and the subsequent recovery of the eclectic information is then provided for all of the signals that have been transported.
