Abstract
The present disclosure is directed to a light source distributor for use in an injection-locked WDM-PON (wavelength division multiplexed-passive optical network). The light source distributor receives an A band and a B band injection optical signals through a single optical terminal from an injection light source for outputting both the A band and the B band injection optical signals; transmits the A band injection optical signal to a first optical multiplexer/demultiplexer of a central office and the B band injection signal to a second optical multiplexer/demultiplexer of a remote node; transmits a wavelength-locked A band optical signal received from the first optical multiplexer/demultiplexer to the second optical multiplexer/demultiplexer; and transmits a wavelength-locked B band optical signal received from the second optical multiplexer/demultiplexer to the first optical multiplexer/demultiplexer.
