We propose and demonstrate an optical multicast overlay scheme on a wavelength-division-multiplexed passive optical network, employing bandwidth efficient inverse return-to-zero-duobinary signals. Multicast control is realized by tuning the voltage bias at the point-to-point downstream modulator at the optical line terminal. At the optical network unit, one photodetector with two decision modules...
We propose and experimentally demonstrate a simple power efficient scheme for WDM-PON, using a LED-based monitoring signal to save the power consumption of the optical transceivers for the inactive subscribers.
We propose and demonstrate optical multicast overlay on WDM-PON employing bandwidth efficient Inverse-RZ-duobinary signal. Multicast overlay control is realized by tuning the bias at the point-to-point downstream modulator at the OLT.
