Performance Analysis
3.1. Power Budget Link
The analysis performed is testing FTTH network performance using Optisystem. Where the
configuration used in the simulator is a real configuration on STO Bandung Centrum. FTTH
implementation with a maximum of 13.248 cores is only installed at a distance of 4 km, so the provider
needs to perform an analysis of network conditions and field needs. After the simulator generates some
parameters, then we calculate the value of Link Power Budget and BER value. In
the analysis of power
budget link value there are 3 (three) parameters analyzed are total attenuation, receptivity and power
margin. The standard used in both simulation and calculation of power budget link is standard from PT.
Telkom. Table 1. is a device specification in FTTH implementation at STO Bandung Centrum.
Link budget calculation uses data on simulation. The data used is the measurement of power by using
Optical Power Meter is original to end. Power budget link analysis is used to determine the performance
level of new cable network installation before it is operated into the device. This analysis aims to adjust
whether the system is running well or not. Tx and Rx power retrieval is done from Optisystem. At power
margin the value of Power Margin must be greater than or equal to 0 dB (Power Margin> 0 dB or Power
Margin = 0 dB). The receive power value is greater than or equal to the receiver's sensitivity of -28 dBm
(PRx> Psensitivity or PRx = Psensitivity). The total attenuation value must be less than or equal to 25
dB. Table 3. is the result of simulation and calculation of power budget link that has been done.
