dc.description.abstract | A Passive Optical Network (PON) is a single, shared optical fiber that uses inexpensive optical splitters to divide the single fiber into separate strands feeding individual subscribers. PONS are called "passive" because, other than at the CO and subscriber endpoints, there are no active electronics within the access network. With the growing inability to meet electricity demands and due to other environmental concerns, low-power design of network equipment has attracted significant research attention. Among access technologies, the Passive Optical Network (PON) technology consumes less power. A WDM-PON solution provides scalability because it can support multiple wavelengths over the same fiber infrastructure, is inherently transparent to the channel bit rate, and it does not suffer power-splitting losses. In the WDM-PON, each ONU can operate at a rate up to the full bit rate of a wavelength channel. Recently, the long reach wavelength division multiplexing passive optical network (WDM-PON) have attracted more attention. However, the long reach optical fiber links must suffer from the limitation of nonlinear distortion. Furthermore, the wavelength-specific laser source in each ONU will increase capital expenditures of system. In this study, the hybrid amplifier (HA) is designed to enhance the signal power and compensate the fiber dispersion over a wide wavelength range. This paper describes the design of a narrowband hybrid amplifier composed of a distributed Raman amplifier and Erbium doped fiber amplifiers for the C-band, using the same pump lasers to estimate the noise figure of configuration. In our proposed approach, the power budget and sensitivity will be improved. In our work we have shown the simulation results of a hybrid amplifier consisting of Erbium doped fiber amplifiers EDFAs and a distributed Raman amplifier in the C-band. We characterize the design by numerical simulation based on the Optisystem 7.0 of an ordinary single mode fiber transmission line. | en_US |
