Abstract:
1. An optical transmission system comprising: an optical transmitting unit that outputs at least one optical signal having a wavelength included in an operation wavelength band; an optical fiber that is connected to the optical transmitting unit, the optical fiber including a plurality of cores separated from each other through each of which the optical signal is transmitted, and a cladding formed around the cores; an applying unit that intentionally applies any one of a bend or a lateral pressure or both to the optical fiber to suppress interferences between the cores; an optical multiplexing unit that multiplexes optical signals output from the optical transmitting unit for inputting the optical signals to the cores of the optical fiber; an optical demultiplexing unit that demultiplexes the optical signals transmitted through the optical fiber; and an optical receiving unit that receives the optical signals demultiplexed by the optical demultiplexing unit.
