Abstract
An identification circuit for a CATV plug-in fixed attenuator is disclosed. The disclosed identification circuit may include an attenuator, a power supply module to supply power, a detection module to detect an output divided voltage value, and a microcontroller unit (MCU) identification module to determine an attenuation value of the CATV plug-in fixed attenuator based on the detected divided voltage value. The power supply module is connected to an input terminal of the plug-in fixed attenuator. The detection module is connected to an output terminal of the plug-in fixed attenuator and to the MCU identification module. With the disclosed embodiments, attenuation parameters can be determined remotely and failures on the line can be located.
