  • Publication number: 20120250008
    Abstract: The present invention obtains a statistical distribution of inter-core crosstalk by measuring the inter-core crosstalk of a multi-core optical fiber while changing the wavelength of incident light in a predetermined range including a specific wavelength relative to the multi-core optical fiber, or while changing a polarization state of incident light entering the multi-core optical fiber. According to the present invention, there is no need to measure the crosstalk by rewinding the multi-core optical fiber and changing the phase difference between cores around the zero point of the equivalent propagation constant difference between cores.

  • Publication number: 20120224808
    Abstract: According to the present invention, as a result of using a depressed or trench-assisted light-receiving waveguide in which the core is surrounded by a layer having a refractive index lower than that of a cladding as light-receiving means for receiving light outputted from a multi-core optical fiber, the layer of a low refractive index can inhibit the propagation of noise, etc. from the cladding to the core. Consequently, even in cases where the inter-core crosstalk is small, it is possible to accurately measure the inter-core crosstalk since components different from crosstalk-derived components in optical power are reduced.
