Abstract In this paper, an OFDM-ROF-PON transmission system at bit rate of 4×10 Gbps is proposed and demonstrated. This paper analyzes orthogonal frequency division multiplexing system for radio over fiber in passive optical network at different input powers. A laser source of 193.1 THz is used with single mode fibers of length 400 km and 500 km. A transmission bit rate of 10 Gbits/sec is used to simulate the OFDM-ROF-PON system. The performance of the system has been analyzed with acceptable Quality Factor and Bit Error Rate at low signal input power in the presence of fiber non-linearities. Also the system does not use any amplifiers and the work is done at higher bit rates. It is analyzed that as the input power increases quality factor also increases and bit error rate decreases.

In order to effectively solve the problem of data transmission security and peak-to-average ratio (PAPR) in an orthogonal frequency division multiplexing passive optical network (OFDM-PON) transmission system, in this paper, a joint encryption scheme of discrete cosine transform (DCT) and selective mapping (SLM) based on chaotic mapping is proposed. In this scheme, the chaotic sequence of a 3D Lorenz chaotic system is used as the row and column index of the DCT matrix and the phase factor of SLM to resist selective plaintext attack, and the system encryption is realized while reducing PAPR. The theoretical analysis and numerical simulation show that the common OFDM-PON, the proposed algorithm, can obtain a PAPR suppression gain of ∼4.8 dB and improve the receiver sensitivity by ∼4 dB BER @ 10 − 3 . In addition, it shows that, with the increase of row/column index mismatch of the DCT matrix, the bit error rate of the system increases gradually. An encrypted data transmission of 8 GB/s 16-QAM optical OFDM signals is successfully simulated over a 20 km standard single-mode fiber, which proves the excellent confidentiality of the proposed secure transmission.

Teknologi serat optik telah dapat digunakan sebagai aplikasi sensor jarak jauh. Selain kemampuannya dalam hal kecepatan dan kapasitas dalam trasnfer data, penggunaan serat optik pada aplikasi sensor jarak jauh adalah karena ukurannya yang kecil serta tidak membutuhkan sumber energi listrik. GPON (Gigabit Passive Optical Network) merupakan standar komunikasi optik yang dikembangkan oleh ITU-T via G.984. GPON memiliki memiliki beberapa keunggulan dibanding standar lain, yaitu: memiliki bandwidth yang besar dan efisiensi yang tinggi. Pada penelitian ini penulis merancang penggunaan serat optik pada aplikasi sensor jarak jauh menggunakan standar GPON pada salah satu client yang terhubung dengan STO BKR, STO PBR, STO RBI dan STO ARK Pekanbaru. Aplikasi sensor ini disimulasikan menggunakan software Optisystem dengan parameter pengujian yaitu power link budget dan Bit Error Rate (BER). Dari hasil pengukuran menggunakan Optical Power Meter (OPM) yang ada di Optosystem, diperoleh nilai level daya penerimaan lebih besar dari -28 dBm dan BER lebih kecil dari 10-9.

Point To Point

The purpose of this study is to compare the existing optical network conditions that use point to point technology with GPON network designed for Udayana University campuses area in Bukit Jimbaran Bali. The Existing optical network is currently able to serve only 14 buildings from 77 existing productive buildings due to the limited number of available optical cores.. It means in order to connect each building at the campuses area, it is required much more optical fiber. Alternatively is using Gigabit Passive Optical Network (GPON) technology. This research was conducted by analyzing the condition of the existing optical network and designing the GPON network. Here are compared some network feasibility parameters ie Link Power Budget, Rise Time Budget and Bit Error Rate. Then compare the use of cores, the number of subscribers as well as device estimation and transmission costs. The study found that to connect all of the buildings are GPON configuration required only 22 optical cores, compared to 154 cores for eksisting network designs. However, the GPON design has lower network quality but is simpler and much more economical if it is implemented for a wide network.

AbstractWe have studied bidirectional lump Raman amplification (LRA) for upgrading the existing passive optical network (PON). We focus on the upgrading to TWDM-PON (or WDM/TDM-PON) systems economically. First of all, we investigate properties of a bidirectional LRA theoretically considering the co-use of 10 G-EPON and TWDM-PON. Then, we investigate them experimentally using a dispersion-shift fiber (DSF) and a high-nonlinear fiber (HNLF). Finally, we made fundamental bit error rate (BER) experiments to confirm the feasibility of the co-use method.

This article focuses on simulation and comparison of line codes NRZ (Non Return to Zero), RZ (Return to Zero) and Miller’s code for NG-PON2 (Next-Generation Passive Optical Network Stage 2) using. Our article provides solutions with Q-factor, BER (Bit Error Rate), and bandwidth comparison. Line codes are the most important part of communication over the optical fibre. The main role of these codes is digital signal representation. NG-PON2 networks use optical fibres for communication that is the reason why OptSim v5.2 is used for simulation.

At the present time and as a result to the recent developed technology demand for higher data rate and capacity has been increased. For the wireless networks, the combination of radio over fiber (RoF) with  (XGPON) Gigabit-capable PON techniques produce a high data rate at lower cost. Thus, this paper illustrates that the performance of RoF-XGPON optical link has been analyzed for multi-channel through combining two multiplexing techniques, such as; Subcarrier Multiplexing (SCM) and Wavelength Division Multiplexing (WDM). The proposed system utilizes  WDM-xGPON and SCM-XGPON architecture combined with RoF technology with 10 Gpbs data rate and (2.4, 5.8, 10 and 15) GHz radio frequency (RF), when change the optical fiber length between (10 to 80) km. The network performance is compared with various digital quadrate amplitude modulation schemes, like ; 4 - QAM, 16 - QAM and 64 - QAM for various input power (-2, 2, and 6) dB. The performance analysis is based on the optical spectrum of transmitted and received signals for 4-channel, constellation diagram, eye diagram, bit error rate (BER), power received, and quality factor. The result explain that the WDM-XGPON-Rof performs better than SCM-XGPON-Rof for different modulation schemes. The bit error rate for WDM-XGPON less than the SCM-XGPON while the power received recorded to the WDM-XGPON greater than SCM-XGPON and the quality factor for SCM-XGPON less than the WDM-XGPON. Therefore The simulation results show that the WDM-XGPON-RoF gives better performance from SCM-XGPON-RoF. The software optisystem version 15 has been used to simulate this system
