10-Gigabit-capable Passive Optical Network (XG-PON), one of the latest standards of optical access networks, is regarded as one of the key technologies for future Internet access networks. In this paper, we propose and discuss the design and implementation of an XG-PONmodule for the NS-3 network simulator. The aim is to provide a standards-compliant, configurable, and extensible module that can...

In this paper, we presents the quality factor evaluation of stimulated Raman scattering (SRS) and four wave mixing (FWM) in optical networks. The nonlinearity effect of stimulated Raman scattering (SRS) and four wave mixing (FWM) with 16-channel optical system. Two parameters are used to evaluate the performance of the optical passive networks. These parameters include transmitting power and qu...

Actin filament (F-actin) is one of the dominant structural constituents in the cytoskeleton. Orchestrated by various actin-binding proteins (ABPs), F-actin is assembled into higher-order structures such as bundles and networks that provide mechanical support for the cell and play important roles in numerous cellular processes. Although mechanical properties of F-actin networks have been extensi...

In this invited paper, software defined network (SDN)based approaches for future cost-effective optical mobile backhaul (MBH) networks are discussed, focusing on key principles, throughput optimization and dynamic service provisioning as its use cases. We propose a novel physical-layer aware throughput optimization algorithm that confirms > 100 Mb/s end-to-end per-cell throughputs with ≥2.5 Gb/...

In the last years, FTTH (Fiber-to-the-home) networks became an excellent solution to deliver broadband internet access and TV services. A furthermore integration of IRUWB (Impulse-radio ultra-wideband) signals into GPON (Gigabit-Passive-Optical-Network) technology is analyzed, with opportunity to allow wireless distribution of high definition video over a future personal area network. It is con...

We report on experimental demonstration of a digital coherent detection link fully based on vertical cavity surface emitting lasers (VCSELs) for the transmitter as well as for the local oscillator light source at the receiver side. We demonstrate operation at 5 Gbps at a 1550 nm wavelength with record receiver sensitivity of -36 dBm after transmission over 40 km standard single mode fiber. Digi...

In this work, we examine the downstream impediments of centralized Ethernet passive optical networks supporting LAN emulation [inter-Optical Network Units communication(ONU)]. The available downstream bandwidth in the centralized scheme is reduced due to LAN emulation and upstream bandwidth allocation functions. The reduction in available downstream bandwidth results in degraded downstream perf...

A Passive Optical Network (PON) is a network technology for deploying access networks based on passive optical components. In a single PON access network, the client terminals are connected to a Central Office through optical splitters and interconnecting fibers where each splitter splits in equal parts the input optical signal coming from the Central Office over its different output fibers. In...
