摘要： An apparatus for measuring Optical Beat Interference (OBI) noise is applied to a central office in a Subcarrier Multiple Access (SCMA) optical network. The central office includes an optical receiver for converting an optical signal received through an optical fiber into an electrical signal. The OBI noise measurement apparatus includes a power divider, first and second filters, and a power measurement unit. The power divider divides the power of a signal output from the optical receiver into two signals. The first filter passes one of the two signals divided by the power divider in a low band of frequencies below a band of subcarrier signals. The second filter passes the other of the two signals divided by the power divider in a high band of frequencies above the band of subcarrier signals. The power measurement unit measures the power of each signal passed through the first and second filters.

摘要： An optical transceiver for transmitting light source control information, which is applied to a Subcarrier Multiplexing optical network, is disclosed. The optical transceiver includes a controller, an SCM frame generation/restoring unit, a modulator/demodulator, and an EO/OE converter. The controller controls transmission of light source control information or collects received light source control information. The SCM frame generation/restoring unit generates an SCM frame containing light source control information received from the controller. The modulator/demodulator modulates an SCM frame generated by the SCM frame generation/restoring unit into a signal suitable for transmission. The EO/OE converter converts a transmission signal modulated by the modulator/demodulator into an optical signal and transmits the optical signal through an optical fiber. An optical network having a telephone office OLT and subscriber ONTs, each having the optical transceiver, is also disclosed.

摘要： Provided are an apparatus and method for processing analog monitoring signals by using a serial bus. The apparatus includes a multiplexer receiving at least one analog signal and outputting only one of the at least one analog signal in response to a predetermined control signal; an analog-to-digital converter converting the output analog signal into a digital signal; a first controller generating the control signal, outputting the control signal to the multiplexer, and controlling the operation of the analog-to-digital converter; and a bus controller outputting the digital signal via an external serial bus. Accordingly, analog monitoring signals are received, converted into digital data, and output via serial bus even when a large number of analog monitoring signals are present, only if the address input to the apparatus is identical to unique address of the apparatus.
