When the data is transferred over the network, a reliable end packet delivery is one of basic requirement of both user and network but there are many major causes that can result packet loss, such as Congestion over the network. Because of this there is requirement of some methodology that can reduce the packet loss and return reliable data transmission over the network. In this paper, the prop...

This paper describes mobile backhaul optical access network designs for future cellular systems, in particular, for those systems that exploit coordinated multipoints (CoMP) transmission/reception techniques. Wavelength-division-multiplexing passive optical networks (WDM-PON) are primarily considered and two proposals to enhance mobile backhaul capability of WDM-PONs for CoMP are presented. One...

Different optical access technologies are studied with respect to their power efficiency. Considered networks provide long-reach optical access. A network model that includes various network and energy related parameters has been developed. The influence of uplink capacity limitation and the amount of broadcast downstream traffic on power efficiency is evaluated within the network model. Long-r...

Enterprise networks are facing disruptive change caused by the use of Internet versus enterprise based applications, increasing video content, integration of voice services onto the LAN, and the transition from wired to wireless LANs. This paper explores this opportunity to adopt Passive Optical LANs (POLs), based on Gigabit Passive Optical Network technology (GPON), rather than continuing with...

Ethernet Passive Optical Networks (EPONs) have attracted considerable attention from industry as they offer a simple, highly flexible and cost effective solution to the problem of providing broadband access to a customer. In this paper, a new approach to bandwidth allocation in EPONs is presented where the Optical Line Terminator (OLT) has full control over the access mechanism. This results in...

One bi-directional passive optical network (PON) based on optical code-division multiple access with interference elimination is proposed. By combining with wavelength division multiplexing (WDM) technique, the proposed scheme alleviates the noise arising during photo-detecting process in the PON. Therefore, the bit error rate performance is improved, which is demonstrated by the results of per...
