<p>A method (10) of configuring a WDM PON comprising an OLT and a plurality of ONTs, comprising:
a. identifying a plurality of OLT ports which do not have an assigned ONT assigned (12), selecting one port (12), and generating and transmitting a wavelength availability signal from the port indicative of an operating wavelength of each port (14);
b. at each of a plurality of unassigned ONTs:
i. receiving said availability signal and tuning a transmission wavelength of the ONT tunable filter until it transmits said signal (16);
ii. generating a wavelength sequence of the operating wavelengths of the ports;
iii. sequentially setting the transmission wavelength of the tunable filter at the wavelengths of the wavelength sequence (20,28) and generating and transmitting a handshake signal at each wavelength (22) until the availability signal is no longer received (30);
c. at the selected port, determining a number of handshake signals received at its operating wavelength (24). If more than one has been received, continuing transmission of the availability signal (26). If only one has been received, ceasing transmission of the availability signal and assigning the originating ONT to said port (30).</p> |
