摘要
In a Wavelength Division Multiplexed Passive Optical Network (WDM-PON) including, a system for overlaying an analog broadcast signal. An Optical Line Terminal of the WDM-PON includes a broadband light source for generating uplink seed light for each uplink channel of the WDM-PON, and a modulator for modulating the analog broadcast signal onto the uplink seed light. An Optical Network Terminal of the WDM-PON receives the uplink seed light from the Optical Line Terminal, and includes an optical divider for dividing the received seed light into a first signal and a second signal; a light source for generating an uplink data signals using the first signal as seed light; and an RF receiver for detecting the analog broadcast signal modulated on the second signal.
