In this paper, on the basis of analyzing theoretically and summing up calculational methods about Bend loss of single-mode fibers, Matlab simulation has been accomplished. Synchronously, it showed the measurements of the bend loss in G.652 fiber for the different bend radius by using OTDR, compared to academic result. Withal, it also performed the(More)
We establish asymptotics and uniqueness (up to translation) of travelling waves for delayed 2D lattice equations with non-monotone birth functions. First, with the help of Ikehara's Theorem, the a priori asymptotic behavior of travelling wave is exactly derived. Then, based on the obtained asymptotic behavior, the uniqueness of the traveling waves is(More)
