Abstract:
1. An optical transmission system to perform optical transmission using a spatial multiplexing optical fiber as an optical transmission line for transmission of signal light, comprising: the spatial multiplexing optical fiber; a transmitting system arranged on one end side of the spatial multiplexing optical fiber, the transmitting system having a light source to emit light, and a modulator to generate the signal light by modulating the light outputted from the light source, in accordance with a predetermined modulation format; and a receiving system arranged on the other end side of the spatial multiplexing optical fiber, the receiving system receiving the signal light from the transmitting system through the spatial multiplexing optical fiber, wherein when a signal light power is defined as P under conditions that a transmission quality Q-factor necessary for error correction in the optical transmission is Q the modulator generates the signal light by modulating the light emitted from the light source, in accordance with the modulation format where said PSR falls within the range of not more than PSR
