A variety of single-mode fiber types can be found in today’s installed networks. Standards bodies, such as the IEC and ITU, recognize four categories of single-mode fiber: dispersion-unshifted (G.652), dispersion-shifted (G.653), cutoff-shifted (G.654), and nonzero dispersion (G.655). Furthermore, there are two varieties of G.652 fiber (conventional and low water peak), and numerous commercial varieties of G.655 fiber (small, moderate, and large effective areas; low, moderate, and high dispersion slopes; negative and positive dispersion), all of which may sometimes be found in a network. This white paper discusses various topics that should be evaluated when mixing TrueWave RS Fiber with dispersion-unshifted and 3 nonzero dispersion fibers.|A variety of single-mode fiber types can be found in today’s installed networks.
