The Implementation Of FTTH In Community Optical Access Network Based On GPON Technology

With the development of network,people have higher requirements on the network they use,for example: higher bandwidth,more stable networks,lower costs,PON technology has achieved these goals well.In many xPON technologies,GPON has the advantages of high bandwidth,large spectral ratio,long transmission distance,diversified bandwidth selection and good Qo S guarantee.It is a good PON technology.When selecting access mode,the location of ONU devices in FTTH mode not only saves costs for operators,but also provides convenience for users,so the FTTH is in the business community in the ideal way of optical access.This paper mainly introduces the principle and performance parameters of GPON technology,and compares three access modes.This paper explains the present situation of the telecom in the bayan nur,analyzes the spectrophotometry and coverage method adopted in the project example in this paper,and explains the advantages of these methods.An example of the project I actually participated in was given,the background of the project construction,the project profile and the selection of various equipment were introduced,and the optical line loss of the whole projectwas budgeted.In terms of engineering construction,the optical roads and ports of the whole project are planned and designed from the practical level,and then the optical roads,addresses and VLAN are planned and constructed from the system level.Finally,the results of the project are shown and the port occupancy of the secondary spectrometer is statistically analyzed.
