Transmission convergence layer in XG-PON

The article deals with the Transmission Convergence Layer in 10 Gigabit passive optical networks. There is a description of conditions, under which the Optical Network Units (ONU) pass through, when is activated. Additionally, this article focuses on the processes of connecting ONUs to the Passive Optical Networks (PONs). The simulations demonstrate that as the number of simultaneous connections to ONU increase, longer wait time for each additional connection becomes. This also solves the collision conditions, that might arise in communication and the Equalization Delay (EqD). Finally, the article deals with the influence of a refractive index on timing relationships. The speed up of the frame transfer between Optical Line Terminal (OLT) and ONUs has been proven.
