摘要: An OADM in a wavelength division multiplexing transmission system includes a wavelength selection switch that selects a predetermined wavelength from a multiple optical signal obtained by multiplexing a phase modulated signal and an intensity modulated signal and outputs the selected wavelength signal to a predetermined output port. The wavelength selection switch has a different delay for each wavelength of the multiple optical signal. For example, the wavelength selection switch includes a mirror array. Optical paths from the surfaces of mirrors arranged on the mirror array to the diffraction grating are different in the case of adjacent mirrors.

摘要: In a chromatic dispersion and dispersion slope compensating apparatus according to the present invention, a WDM light which has been angularly dispersed to a first direction by a VIPA plate, is angularly dispersed to a second direction vertical to the first direction by a diffraction grating, and optical signals of respective wavelengths output from the diffraction grating are reflected by any one of a plurality of three-dimensional mirrors having reflective surfaces of curved shapes different from each other, to be returned to the VIPA plate. Thus, with a simple control mechanism in which the plurality of three-dimensional mirrors are moved to only the second direction, an apparatus capable of variably compensating for the chromatic dispersion and the dispersion slope independent of each other can be provided.

摘要: In a dispersion compensating apparatus, a reference identifying unit identifies a reference (X dB down) that makes a penalty lower than a predetermined value in accordance with optical signal information and a reference identifying table, and a VIPA plate temperature adjusting unit adjusts a refractive index of a VIPA plate by modifying a temperature of the VIPA plate so that a transmission center wavelength derived from the reference matches the wavelength defined by an ITU-T Grid. If a dispersion compensation value setting unit performs an optimal residual dispersion value search, the VIPA plate temperature adjusting unit determines if a filtering penalty is lower than a predetermined value in accordance with a penalty management table. If the filtering penalty is lower than the predetermined value, temperature adjustment of the VIPA plate is not performed.
