摘要： An optical transmitting apparatus is configured such that K pieces of output ports of optical path switching units whose input port is connected to k-th input transmission path are connected to first to K-th output transmission paths except for the k-th output transmission path and to the k-th input port of a dropping unit, and the optical path switching units and the dropping unit outputs light of wavelength which is part or all of WDM light received from said input port from a specific output port, and can output light having a wavelength different from that of the light output from said specific output port from an output port different from said specific output port. Accordingly, while largely reducing the number of optical fiber patch cords necessary in an optical transmitting apparatus and largely reducing the number of spare ports, the flexible expansion of apparatus function can be realized.

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： An address determination circuit makes an address determination of an optical packet to which a destination address and a source address are assigned on a bit-by-bit basis. The address determination circuit has an optical branching section which divides the optical packet into branches, in which each of the branched optical packet contains the same original data, a delay section which delays at least one of the branched optical packets, a bit determination section which determines each bit value of the branched optical packets, and a logic operation section which performs a logic operation on the bit values of the branched optical packets determined by the bit determination section. The delay section delays the branched optical packets so that the logic operation section performs the logic operation on a bit assigned the destination address or the source address and a bit having a predetermined bit value in synchronization with each other.
