"ABSTRAK
Perkembangan teknologi serat optik sebagai media transmisi mendorong perubahan-peruhahan besar dalam merancang sistem jaringan telekomunikasi. Dengan menggunakan serat optik, unjuk kerja jaringan telekomunikasi dapat meningkat dengan baik.
Dalam memasuki era industri, sudah selayaknya Indonesia melakukan pengkajian yang bertumpu pada pemakaian serat optik secara intensif. Dengan serat optik, kecepatan pengiriman data atau informasi dapat dipercepat sampai dengan 500 MPS bahkan lebih.
Penelitian ini menghasilkan pengkajian model jaringan telekomunikasi yang telah menerapkan serat optik terutama untuk lokasi-lokasi gedung perkantoran bertingkat."

"ABSTRACT
In optical fiber communication system , WDM (Wavelength Division Multiplexer) is frequently used for transmitting opticalsignals with different wavelength through one optical fiber line. By the use of WDM , the transmission capacity becomes larger. Therefore , there are several proposed methods for constructing WDM.
In this study an experimental model of WDM system has been designed and constructed by using two optical sources with different wavelengths. The proposed WDM utilizes distributed-index rod lenses as focuser and alignment element of the optical signals.
From the measurement, the performance of the overal1 system shows a reliable characteristics. A low coupling loss of the light transmission and of the mixing circuit has been achieved. Light sources are used consist of two sources with different wavelength."

"Skripsi ini membahas perencanaan SKSO di Kabupaten Administrasi Kepulauan Seribu dengan metode FTTH sebagai jenis transmisi hingga kawasan pengguna yang didorong oleh kebutuhan mendapatkan layanan yang dikenal dengan layanan Triple Play Servicesyang mencakup 3 aspek yaitu data, suara, dan gambar bergerak.Kabupaten Administrasi Kepulauan Seribu yang terletak di bagian utara Jakarta dengan luas daratan sekitar 900 Ha memiliki Pulau Pramuka yang menamakan diri sebagai Cyber Island serta Pulau Panggang yang dijadikan acuan aktivitas telekomunikasi memiliki kebutuhan servis yang cukup besar sehingga dapat dibuat perencanaan jaringan FTTH di kedua pulau tersebut.Dari hasil perencanaan tersebut diperoleh link power budget serta kebutuhan perangkat FTTH sejumlah 2 OLT, 2 ODC port 96, 2 buah splitterpasif dengan rasio 1:2, 4 buah ODP port 12, serta 1 buah ONU port 8FE dan 22 buah ONU port 4FE.

This Thesis discusses the FTTH optical fiber communication systems planning in Kepulauan Seribu as the transmission media from the providers to their respective users that is driven by the need to get the service, which also known as Triple Play Services includes three aspects: data, voice, and video.District of Kepulauan Seribu have a total land area about 900 hectares have Pulau Pramuka that calling themselves The Cyber Island and Pulau Panggang defined as the most representative island have a pretty large service needs so that the FTTH network planning can be made in this 2 islands.In the end, from the results we found the needs of FTTH devicesare 2 OLT, 2 ODC 96 ports, 2 passive splitter with a ratio of 1:2, 4 ODP 12 ports, 1 ONU 8Fe ports, and 22 ONU 4Fe ports. In addition to the acquisition of such devices, power link budget analysis also shows that the plan is in compliance with the standard of quality."

"Kopling antara amplifier permukaan miring dan fiber taper lens-ended diselidiki secara teori. Penelitian teori didasarkan pada model gelombang bidang tiga dimensi yang dihitung melalui pergeseran fasa akibat permukaan iring. Kopling diselidiki berkenaan dengan parameter-parameter berkas dari pandu gelombang amplifier lens-ended, dan juga berkenaan dengan posisi fiber. Terjadinya rugi-rugi kopling karena permukaan miring dan karena variasi dari uji lens yang terbaik, rugi untuk permukaan miring 10° ditemukan lebih kecil dari 0.5 dB dibandingkan amplifier permukaan normal.

The coupling between angled-facet amplifiers and tapered lens-ended fibers is investigated theoretically. The theoretical investigation is based on a three-dimensional plane wave model which accounts for the phase differences introduced by the angled facets. The coupling is investigated with respect to the beam parameters of the amplifier wave guids and the tapered lens-ended fiber, and also with respect to the fiber position. For optimized lens radii the excess loss for 0l0° facet angle is found to be less than 0.5 dB compared to a normal facet amplifier."

"Sistem komunikasi serat optik pada saat ini mempunyai peranan yang sangat penting karena keunggulan-keunggulannya di bandingkan dengan sistem komunikasi yang lain. Untuk dapat mengetahui kinerja sistem serat optik tersebut maka perlu di ketahui parameter transmisinya antara lain, yaitu rugi rambatan (loss) dan pelebaran pulsa (dispersi). Dalam tesis ini dilakukan perancangan dan pembuatan peralatan untuk mengukur parameter transmisi serat optik dengan menggunakan metoda back-scatter, atau yang lebih dikenal dengan optical time domain reflectrometer (OTDR) sinyal keluaran analog sebagai hasil ukur dari OTDR disampling dan dirubah dalam bentuk digital untuk kemudian di proses didalam personal computer untuk dilakukan penghitungan besar loss dan dispersinya. Dari sampel serat optik jenis moda tunggal (single mode) yang diukur dengan peralatan tersebut didapat hasil pengukuran loss : 4,29 dB/km dan dispersinya sebesar 4 µs/km."

"ABSTRACT
As transmission medium in optical communication system, optical fiber is also characterized by elastic properties beside of transmission properties of optical fiber. The Young Modulus of Elasticity of optical fiber could be measured by considering a bare optical fiber as cantilever which resonant with an acoustical vibration. To detect the cantilever vibration, a HeNe laser light is launched into the cantilever of optical fiber through its free end and the output laser light is detected by a PMT and observed by the channel 2 of an oscilloscope. Channel 1 of the oscilloscope observes the signal of the acoustical vibration.
Regulating both the frequency and amplitude of the vibration or the position of the pinhole of the PMT, the resonance frequency of the cantilever could be detected accurately. Using the data of the resonance frequencies of various length of the cantilever has been calculated. "

"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"
