【Abstract】 Positive Dispersion Shifted Single Mode Fiber (POSH), is designed for super transmission rate, high capacity and long-haul system, while move the zero dispersion below 1520 nm and with lower positive dispersion in operation window to suppress the non-linearity effects. POSH fibre made by PCVD process has the best performance simultaneous in optical and geometry properties.更多还原
