    This paper demonstrates a 10 Gb/s one-to-two-wavelength conversion configuration based on cross-gain modulation for optical access networks using a single TW-SOA. The method is capable of converting a signal data of specific wavelength 1541 nm to certain wavelengths of CW’s laser 1554 nm and 1558 nm with 4 nm spacing. The pump power level was classified due to channel response. A result obtained was the best power level offering wavelength converter between −6 and 3 dBm. The conversion efficiency achievement provided an acceptable result for probe signals. The findings of Q-factor performance were investigated. The Q values were found to be more than 9 for point to point transmission and 20 km fiber configurations for the original and converted signal. The technique implemented at 20 km and the power of all channels were adequate to provide a splitting ratio of 1/64 for the launched pump power 3 dBm

    In this paper, the effect of fabrication errors (FEs) on the performance of 1×4 optical power splitter is investigated in details. The FE, which is assumed to take regular shape, is considered in each section of the device. Simulation result show that FE has a significant effect on the output power especially when it occurs in coupling regions

    This paper proposed an efficient network management software tool named Smart Access Network _ Testing,Analyzing and Database (SANTAD) for remote control, inservice transmission surveillance, centralized monitoring, and fault detection for fiber-to-the-home (FTTH) using Visual Basic programming. A virtual network is setup to operate the software tool from central office (CO) or remote point.This program is able to prevent and detect the occurrence of fault in network system through event identification against optical signal level, attenuation, and losses.SANTAD enable each status of transmission link to be displayed a single screen with capability to configure the attenuation and detect the failure simultaneously

    ZnO material characterization was done to be used as optical probes from the plastic optical fiber. Characterization of ZnO materials by processing data obtained from scanning probe microscope (SPM) NTEGRA-AURA. The obtained data is in the form of images with different distance observations. It will be processed by 11 simulated images of proceeds image analysis (IA Analysis). Methodology of data processing is using average scanning Fast Fourier Transformation (ASFFT). This method consists of five characterization data processing techniques, i.e., power spectral density techniques, power spectral technique, magnitude spectrum technique, square root magnitude spectrum techniques and logarithmic spectrum techniques. The goal of average scanning FFT is determines a value of special characterization, because the result of surface morphology from SPM images cannot give exact information . Each techniques in this method will be used to see the details of each ZnO layer surface morphology of in units of frequency or frequency. The observation study of ZnO characterization is made by Atomic Force Microscopy without doing renovation materials. The treatment material as a layer probe of plastic optical fiber sensor was studied for detecting various chemical vapor and air pressure. Based on the detection method called interferometric Fabry – Perot, Plastic Optical Fiber probes will detect the changes of ZnO layer refractive index causes by environments

    This chapter was presented to promote the development of Wavelength Division Multiplexing, WDM networking system based on Polymer Optical Fiber (POF). 1 × 3 POF coupler has been fully utilized to couple the WDM optical signals. An optimum efficiency analysis and mathematical modeling has been conducted to produce an effective device to be integrated into WDM-POF system. But despite its high speed data transmission feature, optical fiber technology remains an expensive option in optical network, although the installation costs associated with fiber through the transmission network can be minimized through the fabrication of 1 × 3 POF coupler. The objective of this chapter is identifying the differences in factors affecting the output power of the POF 1 × 3 coupling. It is then able to develop an efficient WDM-POF network system with high output power at a minimal cost. Several measurements using a power meter record performance and analysis device losses and power outputs. The demultiplexer efficiency is approximately 70%. Demultiplexer fabrication is easy with color and epoxy filters, although for some parts it requires careful attention. The output shows that Ecofriendly WDM-POF Optical Coupler can be used as one of the low-cost media for home networking and automotive applications
