The synergism between the World Wide Web and fiber optics is a familiar story to researchers of digital communications. Fibers are the enablers of the rates of information flow that make the Internet possible. Currently transoceanic optical fiber cables transmit data at rates that could transfer the contents of a respectable university library in a few minutes. No other medium is capable of this rate of transmission at such distances. With the maturing of mobile portable telephony and the emerging broadband access market, greater fiber transmission capacity will be essential in the early 21st century. Since the demand for more capacity drives the development of new optics-based technologies, fiber optics therefore remains a vibrant area for research. Knowing that the basic fiber optic technology is mature means that open questions are more sharply focused and permit deeper mathematic content.

[Next generation optical communication systems will have to transport a significantly increased data volume at a reduced cost per transmitted bit. To achieve these ambitious goals optimum design is crucial in combination with dynamic adaptation to actual traffic demands and improved energy efficiency. In the first part of the book the author elaborates on the design of optical transmission systems. Several methods for efficient numerical simulation are presented ranging from meta-model based optimization to parallelization techniques for solving the nonlinear Schrödinger equation. Furthermore, fast analytical and semi-analytical models are described to estimate the various degradation effects occurring on the transmission line. In the second part of the book operational aspects of optical networks are investigated. Physical layer impairment-aware routing and regenerator placement are studied. Finally, it is analyzed how the energy efficiency of a multi-layer optical core network can be increased by dynamic adaptation to traffic patterns changing in the course of the day, Next generation optical communication systems will have to transport a significantly increased data volume at a reduced cost per transmitted bit.

Penggunaan teknologi serat optik berkembang dengan pesat. Salah satu sistem yang memanfaatkan penggunaan serat optik adalan jaringan lokal akses fiber (Jarlokaf), DLC (Digital Loop Carrier) adalah salah satu jenis teknologi jarlokaf. Apabila suatu sistem DLC gagal (fail) maka akan berakibat hilangnya pemasukan bagi penyelenggara jasa telekomunikasi, kehi1angan pemasukan ini dapat mengakibatkan kerugian yang besar. Probabilitas kegagalan suatu sistem DLC dapat diperkirakan secara kuantitatif dengan menggunakan metoda Reliability Engineering. Reliabilitas dapat diartikan sebagai suatu ukuran frekuensi kegagalan alat dalam fimgsi waktu. Reliabilitas akan mempengaruhi biaya perawatan dan kesinambungan perbaikan. Prediksi reliabilitas yang dilakukan dalam penelitian ini adalah untuk membantu memutuskan jenis pro duk dalam penmilihan sistem DLC. Pada penelitian ini akan dilakukan penentuan fungsi reliabilitas sistem DLC serta mean time between failure (MTBF)-nya sebagai fungsi berbagai jumlah unit komponen cadangan. Sistem DLC yang dianalisis adalah merupakan hasil disain untuk memenuhi kebutuhan wilayah Cengkareug-Jakarta. Selanjutnya dari konfigurasi lengkap tersebut dibuat model reliabilitasnya dengan metoda tertentu. Tabel keadaan dapat dibuat dari hasil model reliabilitas tersebut, kemudian analisis secara rinci dapat dilakukan dengan memanfaatkan tabel keadaan sehingga didapatkan fungsi reliabilitas dan nilai MTBF sistem DLC: yang diamati.

In this research work an experiment on the application of fiber sensor for measuring an acoustic vibration has been carried out. A light beam from He-Ne laser source was into two arms of Mach tender Interferometer. Each arm of the interferometer was a piece of optical fiber with a length of 2 m. The beam transmitting through the sensing arm was modulated in phase by an acoustic vibration produced by a signal generator. The output of this fiber was interfered with the light radiated from the undisturbed fiber, the reference arm of the interferometer. A fringe counter measured a fringe shift due to the vibration of the acoustic signal. The measurement shows a good response in terms of the number of fringes with respects to the acoustic vibration in a frequency range of 10 Hz up to 40 Hz. It is concluded that the system is applicable to measure an acoustic vibration with an accuracy of 7 %.

Dunia telekomunikasi menjadi lokomotif inovasi yang secara fundamental mengubah kehidupan manusia. Perkembangan teknologi telekomunikasi mewujudkan beberapa sistem yang dapat meningkatkan pertumbuhan ekonomi suatu negara serta efektifitas dan efisiensi dalam kehidupan manusia. Meninjau manfaat peran telekomunikasi, Pemerintah Indonesia membangun jaringan backbone serat optik nasional yang disebut Palapa Ring dengan memanfaatkan kontribusi Kewajiban Layanan Universal yang dikelola oleh Kementerian Telekomunikasi dan Informatika (KOMINFO) Republik Indonesia. Namun demikian, Jaringan Palapa Ring memiliki tingkat pemanfaatan yang rendah karena strategi pengelolaan bisnis yang belum matang. Penelitian ini menganalisis strategi terbaik yang dapat diterapkan BAKTI sebagai perwakilan KOMINFO dalam mengelola pelaksanaan bisnis dan operasi Palapa Ring. Analisis strategi dilakukan dengan menggunakan metode kuantitatif strategic planning matrix (QSPM), Analisis SWOT dan IE Matrix. Analisis tersebut dielaborasi berdasarkan hasil evaluasi faktor internal dan eksternal dimana pengumpulan data dilakukan dengan menggunakan metode deksriptif. Strategi terbaik yang dihasilkan dari analisis dalam penelitian ini adalah “Mengkatalisasi pertumbuhan 4G di area rural”. Strategi tersebut menjadi strategi terbaik dari 5 (lima) strategi alternatif yang telah terbentuk. Penentuan strategi terbaik ditinjau dari hasil metode QSPM dimana strategi tersebut memiliki nilai Total Attractiveness Score (TAS) sebesar 3,49.

Telecommunication world is becoming innovation locomotive which fundamentally changing human life. The development of telecommunications technology embodies several systems that can increase effectiveness and efficiency of human life and economic growth of a country. Reviewing the benefits of the role of telecommunications, Government of Indonesia is building a national fiber optic backbone network called Palapa Ring by utilizing the contribution of Universal Service Obligations managed by the Ministry of Communications and Information (MCI) of the Republic of Indonesia. However, the Palapa Ring Network has a low utilization rate due to its immature business management strategy. This study analyzes the best strategies that can be applied by BAKTI as MCI's representatives in managing Palapa Ring business and operations. The strategy analysis is carried out using the quantitative strategic planning matrix (QSPM) method, SWOT Analysis and IE Matrix. The analysis is elaborated based on the results of evaluation of internal and external factors which data collection is done using a descriptive method. The best strategy resulted from the analysis in this study is “Catalyzing 4G growth in rural areas”. This strategy is the best strategy of 5 (five) alternative strategies that have been formed. Determination of the best strategy is reviewed from the results of the QSPM method where the strategy has a value of Total Attractiveness Score (TAS) of 3.49.
