The Choice of Signal Transmission Scheme for the CSRH-Ⅱ

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 frequency sub-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 some difficult technological issues.
