Based on these findings different realization options of wavelength control methods for use in wavelength tunable PON systems are investigated.
(Overlap and non-overlap)-based DBA algorithm with wavelength
ONU scheduling algorithm improves the wavelength bandwidth utilization. In this paper, an (overlap and non-overlap)-based dynamic bandwidth allocation (DBA) algorithm with wavelength
CN102820943B
The invention discloses a wavelength management method between an OLT (optical line terminal) and an ONU (optical network unit) in a TWDM-PON (time wavelength division multiplexing-passive...
Visualization of OLT-and ONU-based wavelength control schemes (OLT
The required control signal can either be generated at the OLT or in the ONU itself as shown in Fig. 2. First, OLT-based wavelength control is discussed in the following.
Universal Wavelength Plan
To support both 25/10 and 25/25 ONUs on the same ODN, OLTs will need a dual rate OLT receiver and DBA, resulting in a variable total US capacity between 10 and 25 Gb/s.
