Zero-Dispersion Wavelength Optimized Single-Mode Multi-Core Fiber for High-Speed Gigabit Ethernet

We demonstrated a single-mode 8-core fiber with the optimum zero-dispersion wavelength for a high-speed GbE system using 175-µm cladding and 250-µm coating diameters. The fabricated 8-core fiber is potentially applicable to 40-km bi-directional 1.6TbE transmission on one fiber.
