| Abstract: | A few feasible OFL（ optical fiber link）schemes of signal transmission （including analog OFL of real-time transmission of full frequency band, analog OFL of alternate transmission of different frequencysub-band, and digital OFL）are analyzed and compared. We give the block diagram of the chosen scheme, the analog OFL of alternate transmission. We also list the calculations about the link and emphasize somedifficult technological issues. |
