PTN And GPON Combined Networking In Metropolitan Area Network

With the advent of 4G and full service operations,the current background is the mainstream of the current international network applications,in the new information transmission pressure and structural layout changes,the need for information transmission path to a profound change,PTN(Transport Network Packet)is mainly based on the Ethernet technology,not only to maintain the traditional advantages of optical transmission,while improving the efficiency and reliability of information transmission,improve the security of information transmission,so that more convenient;The advantages of GPON(Gigabit capable PON gigabit passive optical network for short),because the uplink and downlink asymmetric rate,in line with customer download bandwidth demand is higher than the upstream bandwidth habits,can adapt to the Internet market,transmission distance,provide rich user interface,to achieve a variety of business access,with full-service access capability,compatible and at the same time carrying real-time voice services and high-speed Internet services,and convenient management,management platform relatively complete and perfect,as a kind of ideal passive optical access technology,is the transformation of telecom operators,the positive application to Internet market development and the inherent network..In this paper,based on the PTN+GPON access or convergence network,in the business oriented engineering construction,play the OLT equipment and PTN equipment expertise,to provide operators with the right path to enter the full IP,to provide higher security,greater broadband,longer transmission distance of the optical network.
