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.

The weak direct current (DC) signals detected and converted by the photodetector are output to the mobile phone by voltage/frequency switching, and the signals are processed by the mobile phone APP and audio conversion module. The photodetector is equipped with the automatic switching function to design an optical power meter and detect weak signals. Meanwhile, the optical cable identification system is analyzed and combined with the optical power meter to generate an optical fiber sensing network to improve the weak alternating current (AC) signal detection. This network needs data fusion in sensor nodes’ data collection. The cluster routing protocol is introduced and combined with the back propagation neural network (BPNN) to propose a method suitable for this photoelectric transmission and improve the information fusion and accuracy. In the experiment, the optical power meter is output in gears first, and the output waveforms are normal. The photodiode’s optical power is adjusted to obtain different frequencies on the oscilloscope. In the proposed optical fiber sensing network, weak AC signals are amplified significantly, and different optical fiber lines can be distinguished in the optical cables. The proposed information collection method can reduce network communication and node energy consumption.

Penelitian ini dilakukan untuk menganalisa perbandingan unjuk kerja transmisi teknologi GEPON dan GPON pada jaringan Fiber to the Building (FTTB). Pembahasan perbandingan menggunakan kedua teknologi PON tersebut untuk melihat performansi yang terbaik untuk di aplikasikan pada gedung bertingkat X menggunakan passive splitter dua tingkat dengan rasio perbandingan passive splitter maksimum 1:16. Unjuk kerja transmisi disimulasikan berdasarkan parameter link power budget, rise time budget serta nilai Bit Error Rate (BER) untuk kelayakan sistem jaringan. Perhitungan Unjuk jaringan dibagi menjadi bagian yaitu arah downstream dan arah upstream. Hasil perhitungan didapatkan pada arah downstream jarak terjauh, link GEPON menghasilkan nilai redaman sebesar 22.81 dB, BER sebesar 7x 10-29 dan nilai rise time sebesar 0,2506 ns. Pada link GPON memiliki redaman sebesar 25.94 dB, BER sebesar 3.62955 x 10-12 dan nilai rise time sebesar 0.25 ns. Pada arah upstream jarak terjauh, link GEPON menghasilkan nilai redaman sebesar 4.65 dB, dengan nilai BER ≈ 0 ,dan nilai rise time sebesar,2061 ns. Pada GPON memiliki redaman sebesar 4.65 dB, BER ≈ 0 dan nilai rise time sebesar 0,260 ns. Berdasarkan hasil unjuk kinerja kedua teknologi tersebut dapat disimpulkan bahwa unjuk kinerja teknologi GPON lebih baik dibandingkan teknologi GEPON untuk aplikasikan di jaringan optik gedung bertingkat.
