Fiber To The Home

The utilization of optical fiber cable as a data transmission medium has provided various benefits and advantages in terms of data transfer and economically because it can reduce the use of many copper cables. The purpose of this study was to evaluate the feasibility of Fiber To The Home (FFTH) networks by measuring and analyzing power losses caused by attenuation along the fiber optic cable. Measuring tools for attenuation use JDSU MTS-8000 while the power measurement uses Optical Power Meter. Feasibility specifications refer to ITU-T G.984. recommendations. The analysis results show that of the 110 customers observed, the average value of Link Power Budget is 20.58 dB, with an average power margin of 5.57dBm. If comparing the results of the ITU-T G.984 recommendation, it stated that was accepted, still in accordance with the rules specifications. Feasibility studies of FTTH networks on the issue of power loss and attenuation are needed in an effort to maintain the quality of service to customers. It also has a relationship with planning and developing system installations in the future.

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.

Water Level Monitoring

This paper presents a remote 16 Ch × 200 GHz dense wavelength division multiplexing (DWDM)-passive optical fiber sensor (OFS) network. We particularly investigate the remote water-level monitoring capability of the OFS network based on an optical power measurement that features simplicity and a fast processing speed. The OFS network utilizes a seeded amplified spontaneous emission (ASE) light that is spectrum-sliced and distributed by an arrayed waveguide grating (AWG) towards multiple sensing units (SU), where each SU is installed at a different height in the water pool. Then, each SU reflects either of the two different optical powers according to the medium (air vs. water) back to the monitoring station. Therefore, the total received optical power at the monitoring station linearly changes according to the water level. We can simply recognize the water level by utilizing the optical power meter (OPM) at the monitoring station rather than the optical spectrum analyzer (OSA), which is bulky and expensive and requires a relatively long processing time. Consequently, we can reduce the system complexity, processing time, and cost (both installation and maintenance). However, the OPM-based OFS network requires a new methodology to derive the water level from the measured optical power. Thus, we come up with the reference-to-power ratio () analysis, which can be used for the maximum distance analysis as well as water level recognition. Based on the new reception architecture supported by the new post-processing scheme, the OFS network can distinguish 17 different water levels of the SFP at the monitoring station, which is > 40 km away from the SFP, without using any active devices (such as optical amplifiers) at the remote places.

Nowadays, one of the trends of information and communication networks development is the provision within the shortest time of a larger number of telecommunication services to network users. Currently, connection of subscribers to xDSL communication channels provided by public switched telephone networks (PSTN) is widespread. Providers of classic telephony make active use of these networks due to the low cost of the connection of a subscriber. An obvious disadvantage of this connection type is the limited data transfer rate. Some Internet providers rapidly develop ETTH (Ethernet To The Home) networks. The advantage of ETTH networks is the targeting of the delivery of communication services to subscribers. One of the disadvantages is the operation of a network at the Ethernet level with all typical for this protocol features. The practice of optical networking has existed for many years; however, the basic approach to optical networking is based on the use of active equipment from the access node to users. PON-based (Passive Optical Network) FTTH architecture (Fiber To The Home) is as a rule, compatible with the Ethernet Protocol. The article shows the advantages of the deployment of PON-based FTTH networks, in particular, saving of fiber-optic lines in the area from the optical splitters to the Central telephone exchange or access point by using relevant ports. The article provides the description of access networks architecture applying Ethernet FTTH and PON technologies, and also discusses the prospects for further development of the above mentioned networks.

Fiber To The Home

The evolution of communication network comes from the need for users to stay connected anytime and anywhere. Modernization of the network continues to be done to increase bandwidth capacity in order to obtain an increase in multimedia services, especially in urban areas. Of various transmission media, optical fiber is the best choice to support reliable communication networks. One of the optical fiber communication technologies is Fiber to the Home (FTTH). This study proposes FTTH network design with Gigabit Capable Passive Optical Network (GPON) technology aimed at housing in urban areas. The design uses aerial and duct-aerial cabling systems. The design analysis is carried out based on the parameters of the link power budget, rise time, Bit Error Rate (BER), components and costs required. The value of the power budget link for the uplink and downlink are -22.792 dBm and -23.120 dBm. The rise time value for uplink and downlink are 0.256 ns and 0.258 ns, while the BER value is 14.628 x 10-12. The calculation results show that the design meets the required parameters, hence, the proposed network can be implemented. For the cost components required by the aerial system, it is 11.56% less than of the ductaerial sistem.

In this research, optical communication coding systems are designed and constructed by utilizing Frequency Shift Code (FSC) technique. Calculations of the system quality represented by signal to noise ratio (S/N), Bit Error Rate (BER),and Power budget are done. In FSC system, the data of Nonreturn- to–zero (NRZ ) with bit rate at 190 kb/s was entered into FSC encoder circuit in transmitter unit. This data modulates the laser source HFCT-5205 with wavelength at 1310 nm by Intensity Modulation (IM) method, then this data is transferred through Single Mode (SM) optical fiber. The recovery of the NRZ is achieved using decoder circuit in receiver unit. The calculations of BER and S/N for FSC system at maximum fiber length at 61.2 km equal to 2.30551×10-12, 47.88526 dB respectively. The power budget for FSC system was calculated to be 29 dB. Results show that the BER increases when the received optical power decreases the due to increase of the optical fiber length61.2 km. while S/N decreases. The optical power budget increases as the transmitted optical power increases.
