Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.

Abstract: A frequency divider, which has a cross-coupled inductor-capacitor (LC) structure or a ring structure, is inputted with a direct current (DC) control voltage from an input terminal. By doing so, the frequency divider can adjust an oscillation frequency; and further compensate the input power sensitivity, lower the power consumption and increase the division range. The frequency divider can be used in high-band/high-speed digital or analog communication systems.
