Power Consumption Modeling and Analysis of Integrated Optical-Wireless Access Network

The integration of optical and wireless technologies at access networks are considered as a future solution which provide both high bandwidth and high mobility in an efficient way. GPON is a suitable candidate for optical backhaul due to the combination of higher data rates, greater split ratio and support for triple play services hence it offers maximum flexibility and cost advantages. On the other hand, recent developments of new radio access technologies and introduction of femtocell base stations provide the potential of offering broadband services and applications to everyone and everywhere. However, the power consumption of this network demands a particular attention because access networks are the largest contributor the network related electricity consumption. Therefore, in this paper we evaluate the power consumption of integrated optical-wireless access network which is based on independent ONU-BS architecture. We proposed a power consumption model for such network and the assessment has been done under different simulation scenarios. The constructed model will provide insight of the energy performance of the integrated access network so that in the network design process, focus can be done to the most energy saving strategies

Passively mode-locked laser using an entirely centred erbium-doped fiber

This paper describes the setup and experimental results for an entirely centred erbium-doped fiber laser with passively mode-locked output. The gain medium of the ring laser cavity configuration comprises a 3 m length of two-core optical fiber, wherein an undoped outer core region of 9.38 μm diameter surrounds a 4.00 μm diameter central core region doped with erbium ions at 400 ppm concentration. The generated stable soliton mode-locking output has a central wavelength of 1533 nm and pulses that yield an average output power of 0.33 mW with a pulse energy of 31.8 pJ. The pulse duration is 0.7 ps and the measured output repetition rate of 10.37 MHz corresponds to a 96.4 ns pulse spacing in the pulse train

Dynamic Analysis of UAV’s Motor Support Bar Length Control System

UAV (Unmanned Aerial Vehicle) can be described as aircraft that do not need any presence of pilots inside it. Basically, UAV is come out in a small aircraft sothat the aircraft can be easily controlled by the people from afar[1]. The UAV’s motor support bar length control systems are the UAV’s control systems that move according to the variable arm length movement and also a constant revolution of the propeller speeds. The purpose of the study is to run the dynamic analysis at the UAV’s motor support bar length control systems and also to enhance the UAV’s mathematical modellingby using the SOLIDWORKS®software which involved in using both CAD and CAE systems[2]. The detaileddesign is used SOLIDWORKS®software to conduct the static and dynamic analysis of UAV’s motor support bar length control systems. The design is restricted to the arm due to the critical part that has the highest vibration at the UAV’s motor support bar length control systems. The results that obtain from the study from the static and dynamic analysis are the displacement of the motor, Von Misses stress of the arm, and also the resonance frequency that will give the modes shape to the systems

Channel monitored channel duplexer for optimization of bidirectional passive optical network

Method of optimizing the optical network transmission in access network has been investigated in many years. Unidirectional optical transmission system is the earliest method of delivering the information. In recent years, bidirectional optical transmission system is the most popular network and shall be the first right of refusal to deploy nowadays. It is justify enough by the massive deployment of the popular state-of-the-art network named Passive Optical Network (PON) in Fiber To The Home (FTTH) technologies. Combining 3 wavelengths includes (1) 1310nm, (2) 1490nm, and (3) 1550nm within a fiber is the method used on Gigabit Capable Passive Optical Network (GPON) or Gigabit Ethernet Passive Optical Network (GEPON/EPON). Combining 2 different wavelengths for uplink and downlink on Small Form Pluggable (SFP) lasers also has been a method used to optimized and saved the fiber infrastructure. Compared those techniques, the research optimization focusing on introducing a passive optical duplexer that combined the same wavelength from both end with the element of monitoring via different wavelength to confirm the network availability. In the design, a unidirectional converter able to operate at a nominal 1310nm or 1550nm windows shall be demonstrated up to 10Gbps Ethernet signal

The comparison of dual wavelength fiber laser spectrum in SMF and HNLF by utilizing laser diode

A dual-wavelength erbium-doped fiber (EDF) fiber ring laser in single mode fiber and highly nonlinear fiber is demonstrated and both optical spectrums are compared at 400 mA of Laser Diode (LD) output. The fiber ring laser cavity incorporated sagnac loop had been applied for the laser to lase two wavelengths simultaneously due to high birefringent in polarizaton-maintaining fiber (PMF). Experimental results show that, owing to the contributions of two degenerate fourwave mixings (FWM) in the HNLF and the dual-wavelength proposed fiber laser is quite stable with small fluctuation power in 1.93 dB within 24 minutes in HNLF

A development of optical network unit power consumption model considering traffic load effect

Accurate and precise measurement of energy consumption for the deployment of fiber-to-the-home (FTTH) network using Gigabit passive optical network (GPON) is vital to the research community to develop models for the synthesis of energy-efficient protocols and algorithms for the access network. However, lack of power consumption measurement of optical network devices in the past has led to unrealistic and/or oversimplified model being used in simulations. Usually the access network devices are assumed always on and their consumption is both traffic and time independent. Therefore, in this paper we propose an experimentally-driven approach to i) characterize the Optical Network Unit (ONU) from the power consumption standpoint and ii) develop more accurate power consumption model for the ONU. We focus on ONU since it represents the main contributor to the energy consumption of optical access network. The real data in terms of the power consumption and traffic load have been obtained from continuous measurements performed on a GPON network testbed. The measurement is limited to a maximum 100 Mbps data rate due to a limitation in the sampling rate and precision of the measurement device. However, validation has been done with theoretical power consumption model in order to prove the feasibility of the proposed model. Our measurements show that the power consumption of the ONU exhibits a linear dependence on the traffic in which the power consumption at idle mode is 11.51 W while in low power mode the power consumption is around 7.52 W

Model-free state feedback controller tuning for a liquid slosh suppression system

This paper presents a model-free tuning of a data-driven pole placement state feedback controller for a liquid slosh suppression system. The optimum parameter gains of the state feedback controller are derived utilizing a set of initial input and output data recorded from the discrete-time system. To overcome the existence of the large steady state error when only the state feedback controller was applied, an integral control is added to compensate for such signal. The feasibility of proposed method is illustrated through numerical simulation by comparison with the conventional approach of designing the state feedback controller. The performance of system is investigated based on transient response positioning movement of the cart container, and the level of slosh reduction in the liquid
