ANALISIS REDAMANTERHADAP PERFORMANCEDENSE WAVELENGTH DIVISION MULTIPLEXING (DWDM)PADA SISTEM KOMUNIKASI SERAT OPTIKDENGAN METODE LINK POWER BUDGET DI PT. TELKOM PADANG (STUDI KASUS LINK PADANG – LUBUK BASUNG)
Abstract: The research was
conducted by analyzing the optical fiber attenuation of the DWDM performance in
terms of power received on optical fiber communication systems link Padang-Lubuk
cone in PT. Telkom Padang. Optical fiber has a very small damping. Therefore
optical fibers become the primary choice in telecommunications networks. To
improve the transmission quality is better then the use of DWDM technology,
DWDM technology is a method to insert a number of channels were transmitted in
a single optical fiber. Instruments in this study is the Power Meter and OTDR
JDSU MTS-2000 type, the type of cable used G.655 Single Mode type. Link Power
Budget method is used to determine the performance of DWDM caused by
attenuation based on the value of the received power output receiver. On the
link Padang - Lubuk cone highest attenuation occurs in core 1 of 29.742dB with
100.035 km cable lengths, and the core 10 of 31.8 dB with 119.998 km
cablelengths. Based on the large fault or attenuation/km core 1 of 0.297 dB/km,
the core 10 of 0.265 dB/km and the standard ITU-T was 0.35 dB/km. Value
attenuation/km core 1 and core 10 is still in normal conditions and under
standard ITU-T 0.35 dB/km. Based on optical fiber attenuation, the results of
analysis of the link power budget is the value of Rx is smaller than the value
of Rx sensitivity of -27 dBm, it can be said performance DWDM optical fiber communication
systems in normal and can be used to operate because the power output can still
be accepted by receiver in the device.
