Critical market shares for investors and access seekers and competitive models in fibre networks [PDF]
In this paper we consider and evaluate NGA architectures which meet the foreseeable future bandwidth demand and allow for highest bandwidth and quality for end-users and which no longer rely on copper cable elements.

Propagation impairments due to Raman effect on the coexistence of GPON, XG-PON, RF-video and TWDM-PON [PDF]
, 2013 We analyze propagation effects in the coexistence of GPON, XG-PON, RF-Video and TWDM-PON. We show that high power TWDM-PON channels excite Stimulated Raman Scattering inducing extra-loss on GPON due to power depletion.

Novel Algorithm in Activation Process of GPON Networks
Journal of Communications Software and Systems, 2015 Passive optical networks are dominating access networksaround the world due to its their economical aspect, bandwidth, and penetration. It is necessary to deal with specification of these networks. The article deals with a transmission convergence layer of a Gigabit passive optical network, especially the activation process for ONUs.
