    Abstract: Provided is an OTN traffic management method of a traffic management apparatus included in an OTN line card that accepts OTN traffic and transmits the OTN traffic to a multilayer-integrated fabric switch; or accepts traffic, in units of cells, from the multilayer-integrated fabric switch and transmits, to a network, the OTN traffic that the OTN line card generates. The OTN traffic management method includes restoring a received Interlaken packet to an OTN frame; adding an ITMOH that contains information about an ODU payload size to the OTN frame; converting the OTN frame, to which the ITMOH has been added, into to fabric cell by further adding a fabric overhead; and transmitting the fabric cell to the multilayer-integrated fabric switch.

    Abstract: Disclosed are a terahertz signal generation apparatus and a terahertz signal generation method using the same. The terahertz signal generation apparatus includes first and second resonators configured to respectively output an optical signal of a first resonant frequency and an optical signal of a second resonant frequency from an optical signal input through a gain medium, an optical modulator configured to optically modulate the output optical signal of the second resonant frequency, an optical combiner configured to combine the CW optical signal of the first resonant frequency and the modulated optical signal of the second resonant frequency, and a signal generator configured to generate a terahertz signal using heterodyne beating between the CW optical signal of the first resonant frequency and the modulated optical signal of the second resonant frequency, wherein the first resonant frequency and the second resonant frequency are processed to have a predetermined frequency difference.
