摘要：

We numerically show the applicability of standard 125 mu m-cladding multi-core fiber (MCF) to long-haul and wide-band transmission in the S+C+L band. Although expanding the single-mode bandwidth is an effective way to increase the transmission capacity, the shortened cut-off wavelength degrades the XT and the A(eff). We numerically determine the optimum design of a four-core fiber with W-shape index profile considering the tradeoff relationship among the cut-off wavelength, A(eff), and XT. We show the design and applicability of a standard 125 mu m-cladding MCF for S+C+L band transmission over long-haul distance of 1000 km and above with larger A(eff) is possible from conventional single-mode fiber.
