Abstract :
The OLT calculates the pre-FEC BER using the number of corrected error bits, and decides the optical power of the ONU transmitter. The ONU adaptively adjusts the optical power according to the decision during the discovery window. The power consumption is reduced by 250 mW without any additional devices and without degrading throughput.
