Abstract
Technology development in Indonesia requires the use of a variety of access
media in accordance with geographical conditions, speed requirement, and
available funds. In certain circumstances, a communication system that can be
deployed quickly and efficiently with large enough capacity may be required. One
alternative technology for this requirement is the Wireless Optical
Communications, also known as the Free Space Optics (FSO) communications.
FSO communication is an optical communication technology that uses laser
beams transmitting in free space to transmit data between two points. This
technology can be developed for high speed data rate, which could reach more
than 1 Gbps. One of the factors that influence the performance of FSO systems is
the attenuation under the influence of weather.
In this research, measurements of light attenuation by rainfall in the area of
Jakarta, especially Slipi were conducted. In this work, the loss and the attenuation
coefficient under rain for several months in 2010 were measured, both for heavy
rain and light rain (drizzle) and a model for the relationship of light attenuation by
rainfall was derived. The measurement results are then compared with a
theoretical model proposed by Rensch (Applied Optics, Vol.9, No.7). The
experimental results showed good agreement with the model proposed by Rensch
for rainfall intensity of 0.1 to 0.7 mm / min. However for a very heavy rain the
two results show discrepancy.
From the empirical model of attenuation due to rainfall derived from our
own measurements and the data of the Indonesian Meteorology, Climatology and
Geophysics Council for the year of 2010 on Climatology Station of Pondok Betung for Karet, Jakarta and Curung, Tangerang, a study on the performance of
typical FSO communication system when installed in Jakarta (Pacific Place) and
Tangerang area (campus of the University of Pelita Harapan, Lippo Karawaci) to
local rainy season weather was conducted. The results of this study indicate, that
for the month of January to April 2010 an FSO system between two buildings at
The Pacific Place will have BER fluctuating between 10-13 (without rain) and 4.4
x 10-9 (heavy rain, dated April 5, 2010). Meanwhile, the same system between
Building B and Building D in UPH Karawaci Campus will have BER fluctuating
between 10-13 (without rain) and 4.8 x 10-8 (rain, dated Maret 8, 2010). / Perkembangan teknologi di Indonesia membutuhkan pemanfaatan media
akses yang beragam dan yang sesuai dengan kondisi geografis, kebutuhan
kecepatan, dan dana yang tersedia. Pada keadaan tertentu dibutuhkan sistem
komunikasi yang dapat di-deploy secara cepat dan effisien dengan kapasitas yang
cukup besar. Salah satu teknologi alternatif untuk kebutuhan ini adalah Optical
Wireless Communications yang juga dikenal sebagai Free Space Optic (FSO)
communications. FSO merupakan teknologi komunikasi optik yang
menggunakan pemancaran berkas cahaya laser dalam ruang bebas untuk
mengirim data antara dua titik. Teknologi ini dapat dikembangkan untuk
kecepatan data rate yang tinggi, yang bisa mencapai lebih dari 1 Gbps. Salah satu
faktor yang mempengaruhi kinerja sistem FSO adalah redaman oleh pengaruh
cuaca.
Pada penelitian ini dilakukan pengukuran redaman cahaya oleh curah hujan
di wilayah Jakarta, khususnya Slipi. Dalam pekerjaan ini, diukur loss dan
koefisien attenuasi pada saat hujan selama beberapa bulan di tahun 2010, baik
hujan lebat (deras) maupun hujan ringan (gerimis) dan diturunkan model untuk
hubungan redaman cahaya oleh curah hujan. Hasil pengukuran kemudian
dibandingkan dengan model teoretis yang diusulkan oleh Rensch (Applied Optics,
Vol.9, No.7). Hasil eksperimen menunjukkan kecocokan dengan model Rensch
untuk intensitas curah hujan 0.1 s/d 0.7 mm/min. Namun untuk hujan yang sangat
deras terjadi diskrepansi.
Dari model empiris redaman akibat curah hujan yang diturunkan dari
pengukuran yang dilakukan sendiri dan data Badan Meteorologi, Klimatologi, dan Geofisika untuk tahun 2010 pada Stasiun Klimatologi Pondok Betung untuk
Karet, Jakarta dan Curung, Tangerang, maka dilakukan studi untuk mengaji
kinerja sistem komunikasi FSO tipikal jika dipasang di wilayah Jakarta (Pacific
Place) dan wilayah Tangerang (kampus Universitas Pelita Harapan, Lippo
Karawaci) untuk kondisi cuaca musim hujan tipikal setempat. Dari hasil studi
diperoleh, bahwa untuk bulan Januari s/d April 2010, sistem FSO antara dua
gedung di Pacific Place akan mempunyai BER yang berfluktuasi antara 10-13
(tanpa hujan) dan 4.4 x10-9 (hujan lebat, tanggal 5 April 2010). Sementara itu,
sistem yang dipasang antara Gedung B dan Gedung D, Kampus UPH Karawaci
akan mempunyai BER yang berfluktuasi antara 10-13 (tanpa hujan) dan 4.8 x 10-8
(hujan lebat, tanggal 8 Maret 2010).
