Abstract: PURPOSE: A multi-tap optical microwave filter is provided to reduce cost-bearing, to avoid electromagnetic interference, and to improve filter performance by implementing a self-locked RSOA(Reflective Semiconductor Optical Amplifier) by serially connecting an RSOA, being a low cost light source, and multiple FBG(Fiber Bragg Grating)s with different wavelengths, thereby increasing the number of taps from one light source. CONSTITUTION: An optical filter(100) is composed of an RSOA(110), an FBG(120), and a wavelength-dependent light dispersive medium(130). As for the broadband ASE(Amplified Spontaneous Emission) emitted from the RSOA, lights of certain wavelengths are reflected by the FBG and reinserted into the RSOA. There are N numbers of FBGs, and the light dispersive medium causes fixed optical time delays between N-tap optical signals, obtained by the N numbers of FBGs, for the implementation of a filter.

Abstract: PURPOSE: A high definition video optical transmission system is provided to transceive a high definition image signal, a control signal, and a data signal through one optical path without confusion. CONSTITUTION: A control/data mixer(120) generates a control/data signal by mixing a control signal with a data signal. Frequency increase converters(130,140) perform the frequency increase conversion of the control/data signal. A mixer(160) mixes an image signal with the control/data signal. An electrophotic converter(170) converts each of the mixed signals into an optical signal to transmit the optical signal to an optical path.

Abstract: PURPOSE: A distributional media access control protocol based vessel logistics system is provided to solve the problem that information of an RFID reader is not able to be transmitted to a vessel logistics system server due to inconsistency of the communication standard when an RFID mounted in a container for vessel logistics moves to a vessel logistics warehouse in other region. CONSTITUTION: A super frame is divided into a BP(Beacon Period) and a DTP(Data Transfer Period). The BP is divided into a plurality of small beacon time slots to transmit their own beacon frame. The representative IE(Information Element) capable of transmitting in a beacon frame is a DRP(Distributed Reservation Protocol) IE and a DRP Availability IE and exchanges resource reservation information and control information using a DRP IE and a DRP Availability IE and reserve resources.

Abstract: PURPOSE: A wi-media resource reservation method for constructing a wi-media network is provided to reserve other links by passing through a relay device or a direct link. CONSTITUTION: When data is transmitted and received in an MAS(medium access slot) S-R(S518), a DRP(distributed reservation protocol) IE(information element) for a reservation target node set as a reservation detail state code of a relay notification is confirmed(S522). It is determined whether the data is transmitted and received through an MAS R-T(S524). When a relay node is able to use the MAS S-R and the MAS R-T, MAS R-T information for continuously transmitting the data is stored(S526). The DRP IE set as a relay approval reservation state code is transmitted to a reservation subject node(S528).
