Patent ID: 7664406

Claim:
An optical line terminal in a wavelength division multiplexing passive optical network, the optical terminal line comprising: a main board having a master optical transmitting/receiving control/supervising section; and a sub board having a plurality of optical transceivers and a slave optical transmitting/receiving control/supervising section, wherein the master optical transmitting/receiving control/supervising section produces a data input signal and a data read-control signal to control the plurality of optical transceivers of the sub board, and wherein the slave optical transmitting/receiving control/supervising section receives the data input signal and the read-control signal and processes the data input signal based on the read-control signal, and wherein the optical transceivers are controlled based on the data input signal, wherein the master optical transmitting/receiving control/supervising section comprises: a clock producing section to produce the read-control signal and to transmit the read-control signal to the slave optical transmitting/receiving control/supervising section; a controlling section to provide optical transmission control signals to control the plurality of optical transceivers; a parallel matching section to convert the optical transmission control signals to serial data; and a serial matching section to arrange the serial data received from the parallel matching section, to produce the data input signal and to transmit the data input signal to the slave optical transmitting/receiving control/supervising section.
