Abstract :
The needs and development of the community for internet-based services
today are more diverse because not only voice services are provided, they are also
video and data. Braling Grand Hotel Purbalingga is one of the recommendations
for the implementation of the FTTB network to support internet services for
customers. This study discusses optical network access from STO to the customer's
ONT and supports the design of optical network access, analyzes the results of the
calculation of the power link bugdet and compares the results of the calculated
values and the results of the conversion values. Based on the results, the calculation
of the budget link obtained on the downstream side is -20.8755 dBm which is the
total value from STO to ONT while for the comparative value is -23,513 dBm with
a power reserve value of 2 dBm. Based on the simulation results and the difference
calculation of 2.6345 dBm, this is related to the transmit power in the simulation -
0.596 dBm. The performance results of the BER and Q factor parameters were
obtained from the simulation results with a BER value of 1.50001 x 10-58 for a Q
value of a factor of 16,899 so that optical access planning at the Braling Grand
Hotel Purbalingga was approved that had met ITU-T G987 stand
