Abstract

Recent laboratory demonstrations of long-distance large-bandwidth monomode systems have been followed by several successful field-installed links. They have shown that monomode fibers can be placed in cables, pulled into ducts, spliced, and measured in realistic environments. To achieve the performance required by the system's designer, the optical characteristics of the fibers in a real link must be prudently chosen to minimize total transmission loss. We shall consider the fiber design which satisfies this criterion for fibers that are loss-limited at 1.3 and 1.55 μm, that is, in the notation of Ainslie et al.,¹ type B matched-cladding fibers with zero total dispersion of ~ 1.3 μm.
