摘要： An optical add-drop multiplexer (OADM) for adding and dropping wavelength groups for each node among multiplexed and input wavelength groups includes: a wavelength group demultiplexer for separating a plurality of input channels into groups of channels and dropping a channel group required for the node and passing the other groups of channels therethrough; a channel selector for selecting channels from the wavelength group output from the wavelength group demultiplexer and transmitting the selected channels to the area; a channel multiplexer for multiplexing the channels having the same wavelengths as those of the selected channels and input from the area into the wavelength group, and a wavelength group multiplexer for adding the wavelength group input from the channel multiplexer to the wavelength groups that have passed through the wavelength group demultiplexer. Wavelengths required for each node are set to a wavelength group, thereby reducing the time necessary in extending channel capacity or wavelengths in each node. Also, since only a channel selector is additionally installed in an OADM for wavelength extension, wavelength extension is facilitated and a WDM system can be constructed at a low cost. Such an OADM may be used in a wavelength division multiplexing (WDM) optical link.

摘要： An optical attenuator using an isolator, and an optical communications system including the same, function to control the intensity of an input optical signal. The isolator comprises a Faraday rotator in which a rotation angle of polarization varies depending on the intensity of an applied magnetic field. As a result, the level of isolation of an optical signal changes in accordance with the rotation angle of polarization and an attenuated optical signal is outputted. A magnetic field generator generates a magnetic field having an intensity which is controlled by the intensity of current, and the generated magnetic field is applied to the isolator A power supply supplies current to the magnetic field generator and controls the intensity of the current. A magnetic core and a coil are installed on the optical isolator, and currents applied to the coil are controlled to adjust the intensity of the magnetic field which is formed on the isolator. Accordingly isolation of an optical signal is controlled, and the optical signal is attenuated. The optical attenuator is easily mounted on the system because of its small size, and can change the level of attenuation by controlling only the intensity of current.

Thus, an entirely flat gain is kept.

摘要： An long-wavelength optical fiber amplifier includes an erbium doped optical fiber (EDF) for amplifying an input signal light having a wavelength in the range of 1580 nanometers (nm) using pump light, a pumping unit positioned in front of and to the rear of the erbium doped optical fiber, for supplying the pump light to the erbium doped optical fiber, and an amplified spontaneous emission (ASE) reflecting unit positioned in front of the pumping unit, for coupling backward amplified spontaneous emission generated in the erbium doped optical fiber to the long-wavelength input signal light and inputting again the same to the erbium doped optical fiber. Fewer laser diodes and optical devices are necessary in amplifying an signal light having a long wavelength, by providing a reflector for reflecting amplified spontaneous emission. Also, the gain is increased in the case when the power of an input signal is small.

摘要： An optical modulator using an isolator, and an optical transmitter including the same are provided. The optical modulator modulates a carrier wave generated by an optical source according to a predetermined electrical signal. An isolator in the modulator includes a Faraday rotator in which the rotation angle of polarization is different according to the intensity of an applied magnetic field. The rotator controls isolation of an optical signal according to the polarization rotation angle and outputs a modulated optical signal. A magnetic field generator produces a magnetic field whose intensity is controlled by a predetermined electrical signal, and applies the produced magnetic field to the isolator. A signal generator supplies the electrical signal to the magnetic field generator and controls the intensity of the electrical signal. The magnetic field generator is mounted on the optical isolator, and the electric signal applied to the magnetic field generator is adjusted to control the intensity of the magnetic field formed in the isolator. Accordingly, isolation of an optical signal is activated or deactivated, thereby modulating a continuous wave optical signal. Thus, a small and cheap optical modulator having an excellent temperature property can be realized and easily housed in the transmitter.
