As a promising technology for broadband communication, Passive Optical Network (PON) has been deployed to support the communication in smart grid system. This paper theoretically analyzes the influences on Directly Modulated Laser (DML)-based PON system performance including Bit Error Rate (BER) and power budget. First, we establish the DML-based PON system model, and then the system performances are simulated under different linewidth enhancement factor, received optical power and fiber length. Simulation results show the increase in received optical power to maintain a given BER due to fiber nonlinearities. This research provides a theoretical guidance on the PON system design.

Fiber To The Home

Fiber optic merupakan teknologi yang menyediakan kapasitas bandwith besar dengan kecepatan tinggi, tidak dipengaruhi interferensi gelombang elektromagnetik, Sejalan dengan berkembang secara pesatnya penggunaan serat optik sebagai medium penghantar, ada kemungkinan terjadinya hilang informasi akibat kerugian dari pemanjangan kabel fiber optic ataupun penyambungan kabel fiber optic, kerugian tersebut yaitu redaman. Dalam penerapan metode link power budget, perhitungan redaman dilakukan dengan data yang diperoleh berdasarkan standarisasi dan pengukuran menggunakan perangkat optical power meter. Hasil analisa perhitungan, sistem mampu dalam keadaan normal menggunakan layanan gigabit passive optical network dapat diterima oleh perangkat akhir jaringan fiber to the home pada pelanggan perusahaan PT MNC Kabel Mediacom yang berada di Kelurahan Jati RW 02 Pulo Gadung Jakarta Timur.

Budget Analysis

The purpose of this article is to propose a new configuration based on OCDMA and Fast-OFDM techniques for access network applications. A hybrid intensity modulation with direct detection, fast orthogonal frequency-division multiplexing–code division multiplexing access (IM/DD Fast-OFDM-CDMA) system is analytically and numerically evaluated for an amplifier-free access network. Therefore, system performance is analytically investigated in terms of bit error rate/Q-factor as a function of simultaneous users, fiber length and launched optical power. Firstly, the proposed analytical model includes the overlapping effect among OFDM subcarriers, the peak-to-average power ratio (PAPR), and multiple access interference (MAI). Secondly, a simulation setup is performed, allowing four simultaneous users operating at 40 Gb/s in a passive optical network (PON) context. Furthermore, a power budget analysis is made between IM/DD Fast-OFDM-CDMA, all-optical IM/DD OFDM-CDMA (IM/DD AO-OFDM-CDMA) and OCDMA wavelength division multiplexing (OCDMA-WDM) configurations. It is shown that at 40 Gb/s and by using 2D-hybrid coding (2D-HC), the maximum achievable transmission-reach of IM/DD Fast-OFDM-CDMA is 142 km, which is 34 km and 60 km higher than those provided by the IM/DD AO-OFDM-OCDMA and OCDMA-WDM PON configurations, respectively.

AbstractIn this manuscript, an attempt has been made to enhance the performance of colorless wavelength division multiplexed-passive optical network (WDM–PON) system using a combination of dual-drive Mach–Zehnder modulator and single sideband-suppressed carrier (SSB-SC) technique along with splicing. The proposed design makes use of SSB-SC technique for optical line terminal (OLT) as well as for optical network unit (ONU) that is generated by using dual-drive modulator which in turn reduces the expense for complete communication process. Suppressed RF signals with four channels at a bit rate of 10 Gbps for each channel are multiplexed before injecting into fiber span of 25 km at OLT side. Half of the downlink power is consumed for re-modulating the data signal at ONU side. The performance is further improved by using signal splicing method. Due to suppression in the carrier in this technique, there is no carrier Rayleigh scattering problem. The proposed model is compared with the existing one for error-free transmission of signal. The results revealed that the proposed model possess less value of bit error rate with the same value of received optical power as well as channel.
