ABSTRACT
The Optical Fiber Communication System uses an optical cable as a
signal transmission medium from the transmitter to the receiver in
the form of light. SKSO is used primarily to improve the ease in
obtaining information operational system power grid. Substation
(GI) as one component of power grid is monitored and controlled
through Supervisory Control And Data Acquisition (SCADA) system
centered in Distribution Control Center (DCC) through fiber optic
transmission media.Presence of intermittent between graphical
screens in SCADA under real-time device conditions in GI causes
delayed alarm status.Based on calculating and simulations show the
performance of SKSO in PT. PLN (Persero) DCC Purwokerto
generally quite good, with 99,97% availability, power receive real
condition 6,92dB or Better 4,4dB compared to simulation and 0,2dB
difference from theoretical calculations. However, the reliability is
bad, worth of MTBF 104hours/732uptime or 0,011872 / year. The
intermittent that occur along the GI-DCC link are not causes by the
poor optical fiber transmission system but are indicated by
reliability parameter. This is reinforced by simulation measurement
result that have the ITU-T G957 standard with BER gain reaching
8,25 x 10-44and 13,81 for Q-factor.There is a decrease in received
bandwidth obtained by 25% of the total bandwidth that should be
received due to the amount of rise time budget.
