PON REACH EXTENDER AND METHOD THEREOF BASED ON TUNABLE OPTICAL TRANSCEIVER

摘要

Provided are a passive optical network reach extender based on a wavelength tunable optical module and a method thereof. According to an embodiment of the invention, the passive optical network reach extender includes: a first optical splitter configured to receive an optical signal from an optical line terminal and split the signal into optical signals having multiplexed wavelengths; a wavelength tunable remote relay configured to receive the optical signals split from the first optical splitter, and select and control an available wavelength for each port; a wavelength multiplexer configured to multiplex the wavelength of the optical signal outputted from the wavelength tunable remote relay; and a second optical splitter configured to split the optical signal multiplexed by the wavelength multiplexer into a plurality of optical network units.
