Remote radio head

A remote radio head comprising:

• at least one integrated connection terminal that integrates at least one optical signal with at least one power source so as to receive the integrated optical signal;
• a power supply unit that receives power source from the integrated connection terminal, and supplies the converted power source by converting the received power source into internal driving power source of a corresponding remote radio head;
• a photoelectric/electrooptic conversion unit that receives an optical signal output from the integrated connection terminal so as to convert the received optical signal into an electrical signal;
• a framer that reconstructs the electrical signal converted in the photoelectric/electrooptic conversion unit according to a pre-configured signal demodulation format;
• a digital signal processing unit that receives the signal output from the framer so as to perform level adjustment and waveform adjustment in a digital level;
• and
• a transmission and reception signal conversion module that converts a signal output from the digital signal processing unit into a wireless transmission signal of a high frequency, amplifies the signal at a high output power so as to output the signal to a side of an antenna.
