Abstract :
Technological developments in the telecommunications industry affect lifestyle that
develops in society. The desire for communication that was originally only in the form of
voice and data services has developed into broadband or tripleplay services (voice, data
and video). In this final project fiber to the home is implemented at Graha Permata
Selabaya Housing because of its need for fast access such as wi-fi services for each home
unit. The distance with OLT to the farthest ONT is only 4.53 km and the technology used is
gigabit passive optical network (G-PON). Downstream calculations are carried out
because the triple play service uses more downstream processes than uses upstream The
wavelength used is downstream 1490 nm. The measurement parameters that will be
considered are the power link budget, Bit Error rate, and Q-factor. Manually downstream
link budget calculations, both the closest and farthest distance, obtained power values of -
18.8769 and -19,689 dBm, with power margins of 3.1231 and 2.311. From the simulation
results obtained power values of -20.357 dBm and -21.7 dBm, BER values are 1.11074e -
123 and 5.06027e-94 and Q-factor values are 23.6228 and 20.5363. Judging from
calculations and simulations, the value meets the ITU-TG. 984.2 standard.
