Abstract: An apparatus for transmitting failure information between an Ethernet and an SDH network and a method therefor are provided to transmit OAM information to other networks using an existing MAC control frame in interfacing between an Ethernet and an SDH network when there is failure on the Ethernet or the SDH network, thereby operating and managing an EoS(Ethernet over SDH) network effectively. A frame transceiving unit(10) transceives an Ethernet frame through plural optical transceiving ports and detects the failure of a physical link. An MAC(Media Access Control) processing unit(20) reads the header information of the Ethernet frame received by the frame transceiving unit to detect an OAM(Operations, Administration and Maintenance) frame and status information by port, and generates an OAM frame using status information by port and transmits the generated OAM frame to the Ethernet through the frame transceiving unit. An SDH(Synchronous Digital Hierarchy) processing unit(30) receives status and failure information about the Ethernet to generate a corresponding SDH OAM frame. An output interface unit(40) receives the frame generated in the SDH processing unit and outputs the received frame to an SDH network. A signal processing unit(60) receives the failure information detected in the frame transceiving unit to generate a corresponding OAM signal, and transfers status and failure information on a network for generating the SDH OAM frame generation information from the OAM frame generated in the MAC processing unit to the SDH processing unit.

Abstract: PURPOSE: An apparatus for checking a WDM optical signal is provided to measure a channel-based wavelength and power and an average optical signal noise ratio(OSNR) of a wavelength division multiplexing(WDM) at the same time. CONSTITUTION: An apparatus for checking a WDM optical signal performance includes an optical splitter(20), a 1xN optical coupler(30), an optical fiber bragg grating(40), an optical detector, an amplifier(60), an analog/digital converter and a signal processor(80). A WDM signal(11) is formed of optical wavelengths(λ1, λ2, ..., λn-1) and is obtained based on a tapping from an optical transmission path. The WDM signal separated from the optical transmission path is inputted into an input port(21) of the optical splitter(20) and is inputted into the input port(31) of the 1xN coupler(30) through an output port(22). The optical splitter prevents the optical signals reflected by the optical fiber bragg grating from being coupled to the optical transmission path. The 1xN optical coupler(30) distributes the WDM signals to each output port(32-0, 32-1, ..., 32-n-1) based on a certain insertion loss.
