Document Type and Number:
WIPO Patent Application WO/2017/104905
Kind Code:
A1
Abstract:
The present invention relates to a method for compensating for optical transmission delay by an optical transmission delay compensation apparatus including a main device and a remote device which are connected by an optical transmission line, the method comprising the steps of: receiving, by the remote device, a reference signal, generated by the main device, through the optical transmission line; performing analog conversion and analog processing of the reference signal; converting the reference signal, for which analog processing has been performed, into an RF signal and radiating the same; and measuring a delay time from the generation of the reference signal to the radiation thereof as the RF signal. Accordingly, the present invention can synchronize remote devices so as to prevent service quality from being degraded by interference, and to improve the service quality.
