    Abstract: The present invention provides a method of optical transmission delay compensation of a system including a main unit and a remote unit, wherein the main unit and the remote unit are connected to each other through an optical transmission line, including: receiving a reference signal, by the remote unit, generated by the main unit through the optical transmission line; analog converting the reference signal and performing analog processing on the reference signal; converting the analog-processed reference signal into an RF signal and radiating the RF signal; and measuring a delay time until the reference signal is generated and radiated as the RF signal. Accordingly, it is possible to obtain an effect of preventing degradation of service quality due to interference by synchronizing remote units and improving the service quality.
