A G.984 GPON exhibiting multi-wavelength protocol functionalities

A Gigabit Passive Optical Network (GPON) upstream-map frame- format enhancement has been developed to accommodate dynamic multi wavelength (DMW) transmission over splitter-based GPONs. Accordingly network functionality has been supported by means of an algorithm, managing bandwidth allocation among utilised wavelengths in a dynamic two dimensional protocol. Modelling of the performance characteristics of the DMW-GPON topology in OPNET has demonstrated a minimum of 100 Mbit/s bandwidth provision for each of 32 Optical Network Units (ONUs) with a maximum 0.085 s packet delay for the worst performing lower service level agreement (SLA) ONUs.
