| Abstract: | We first briefly explain the physical meaning of equal-length transmission optical-fibers,as well as a few schemes of realizing such optical-fibers.We then determine from analysis the requirement on length errors.We also list two methods for measuring lengths of optical-fibers.Phase errors of the fiber transmission for the CSRH are analyzed and calculated.We finally describe some measurement methods of optical-fiber phases. |
