So far, pulse width shortening fibers (PFs) and fiber Bragg grating (FG) used individually in most of the reported studies, however pulse width shortening (PWS) took either high cost (in PFs) or lower PWS efficiency (PWSE) (in FG).
However, pulse width increase (PWI) in the optical fiber limits the overall distance reach and also introduces more bit errors which needs to addressed. Optical communication systems introduced paradigm shift in the forte of data transmission at higher speeds and over longer distances where, on contrary electrical transmission systems failed due to higher amplitude degradation, interferences and lower bandwidths. A 4 × 10 Gbps L-Band PON is investigated over 40 km feeder fiber (FF) and 1 km drop fibers (DFs) that serve 32 optical network units (ONUs)/different input powers, dispersion values, and laser linewidths in terms of reflective power of FBGs, eye opening factor, and bit error rate (BER), respectively. (1) ASEN reflection for fault monitoring and (2) dispersion compensation is proposed. Therefore, in this work, a fault detection/monitoring system for L-Band PON using C-Band ASEN from inline erbium doped fiber amplifier (EDFA) and dual purpose FBG, i.e. So, in L-Band PONs, a cost-effective, low-complexity fault detection/monitoring system is required. However, interference occurs when ASEN and transmitter signals are in the same wavelength band, and adding additional ASEN sources to the network raises the overall cost. Fault detection in the conventional band (C-Band) employing reflecting Fiber Bragg Gratings (FBGs) and a probe signal integrating an additional amplified spontaneous noise (ASEN) source has been frequently demonstrated. Because of PONs requesting more and more channels, fault detection/monitoring is critical. It is a significant issue in communication system noise source in WDM systems are amplifier noise & thermal noise in receivers.Long band (L-Band) passive optical networks (PONs) are attracting a lot of attention these days, thanks to rising capacity demands. It is the process of conveying message signal, a digital bit stream or analog audio signal inside another signal can be physically transmitted. We implement fiber optic communication in optisystem by Modulation: BER optimization in fiber optic communication: We divide bit error rate by total number of transferred bit during a studied time interval.Įye diagram analyzer block of optisystem software display multiple trace of modulated signal to produce eye diagram.In digital transmission we alter the number of bit errors due to interference distortion, noise or synchronization error.We provided the simulation models are: Bit error analyzer: OPTISYSTEM PROJECTS FOR STUDENTS Simulation model for ROF system analyzer:
