ABSTRAKSI: Jawa Backbone merupakan jaringan transmisi Sistem Komunikasi Serat Optik (SKSO) yang menghubungkan daerah-daerah yang ada di pulau Jawa dan memiliki peranan yang sangat penting dalam kegiatan komunikasi. Seiring dengan kebutuhan pelanggan akan kegiatan berkomunikasi yang semakin meningkat, terlebih lagi di pulau Jawa yang memiliki kepadatan penduduk yang paling tinggi di Indonesia, maka evaluasi dan peningkatan performansi terhadap SKSO akan selalu dibutuhkan baik dalam segi jaringan transmisi maupun kemampuan perangkat agar kebutuhan pelanggan selalu terpenuhi.
Pada tugas akhir ini, dievaluasi kinerja SKSO pada area Jawa Backbone ring-1, di mana teknologi multiplexing yang digunakan adalah Dense Wavelength Division Multiplexing (DWDM). Evaluasi dan analisis dilakukan berdasarkan beberapa parameter yaitu link power budget, rise time budget, maintainability, availability, reliability, dan gangguan yang terjadi.
Dari hasil evaluasi selama periode 1 Januari 2009 – 30 April 2010, diketahui nilai MTTR (Repair) rata-rata sebesar 4,87 jam (memenuhi standar), nilai MTTR (Recovery) rata-rata sebesar 9,69 jam (tidak memenuhi standar), dan availability rata-rata sistem sebesar 99,67% (tidak memenuhi standar). Hal ini menandakan bahwa kualitas performansi sistem belum cukup baik. Diketahui juga selama periode tersebut, gangguan dominan yang terjadi adalah kabel putus yang disebabkan oleh pihak ke-3.Kata Kunci : SKSO, Jawa Backbone ring-1, DWDM, performansi.ABSTRACT: Java Backbone is a optical fiber communication systems transmission network that connect existing areas in Java Island and has a very important role in communication activities. Along with customers need toward communication activities will always increasing, especially in Java Island which has the highest population density in Indonesia, the evaluation and improvement the performance of optical fiber communication systems will be needed both of transmission networks and the ability of the devices, so the customers need are always met.
This final project evaluates the performance of optical fiber communication systems in Java Backbone ring-1 area, where the multiplexing technology used is Dense Wavelength Division Multiplexing (DWDM). Evaluation and analysis is based on some parameters i.e. link power budget, rise time budget, maintainability, availability, reliability, and the disturbance occurred.
From the evaluation results during the period January 1st, 2009 – April 30th, 2010, known the value of average MTTR (Repair) is 4.87 hours (meet the standard), the value of average MTTR (Recovery) is 9.69 hours (did not meet the standard) , and the average availability system is 99.67% (did not meet the standard). This indicates, that the quality of system performance was not good enough. It is also known during that period, the dominant disturbance that happened was a broken cable caused by 3rd party.Keyword: Optical Fiber Communication Systems, Java Backbone ring-1, DWDM, performance.
