Epon details on Access Network Technology

At present, the access network technology is developing very rapidly, and many new technologies have emerged. Especially when wireless technology is about to become mainstream, it can meet more people's needs, the Epon technology is described in detail here. Currently, the access network is facing a series of technological and business model revolutions and challenges. Changes in user business needs and Industry Integration bring about new competition, traditional Telecom operators use ADSL or LAN access network technology. However, with the new business needs, traditional methods cannot meet the requirements and the cost of network transformation is high. As a radio/TV network operator, how to build a new access network technology, have the ability to carry out multiple services, and have the potential to expand the network, which needs to be carefully considered in current network construction. Only by building a basic network that can meet future multi-business needs can we gain development opportunities in the new market competition environment.

At present, there are two directions for the development of communication networks. One is that the transmission layer shows the development trend of all-optical networks. From the ASON technology on the core layer to the FTTP technology on the access layer, there is no indication that the evolution of network bearer to light; in addition, service integration is based on IP addresses. The development of INTERNET makes IP addresses the most ideal service bearer protocol, MSTP, RPR, MPLS, and other technologies are not the result of mutual reference and integration between traditional transmission networks and packet switching networks. The rapid development of IPTV and VoIP also shows the development direction of IP bearer. The network construction of the access network system should grasp the development trend of technology and market, and select a reasonable technology to build the access network technology.

This solution provides an optical access network solution based on the EPON technology. The solution uses the EPON technology to implement the FTTH Network to fully reflect the advantages of Ethernet and IP services, with three-in-one Triple Play) business support capabilities. The solution uses shengliya's SALIRA 2000 platform to build an optical fiber access network. SALIRA Systems, Inc.) is a leading manufacturer of Optical access Network equipment and maintains a leading position in the GEPONGigabit Ethernet Passive Optical Network field. Currently, shengliya has many successful commercial cases in China and abroad, with mature products and reliable technology.

As an emerging access network technology, EPON is very suitable for FTTB/FTTH optical fiber access networks. From the operator's point of view, passive features can reduce construction, management, and operation costs, improve the return on investment and new profit opportunities. The architecture of the EPON network is very in line with the technical construction of the access network, so that operators can quickly and effectively carry out business and facilitate network expansion; the high bandwidth provided by EPON will meet users' increasing network bandwidth application needs, so that operators can carry out multiple services with reliable network resources. The EPON network has good compatibility, it can be well integrated with existing networks. while providing the above advantages, EPON also has the incomparable economics of other FTTx technologies, which can reduce investment and long-term construction costs.

Requirement Description

This time, the data access network technology is deployed in a residential area to provide data access services at the initial stage. At the same time, it prepares for IPTV. Once the time is ripe, it provides IPTV services to customers and high-quality network services. A total of 248 buildings and 690 residential units are built in seven standard sections in the Community, with a total of 9108 households. There are also several commercial, school, and government buildings. In the initial stage, we will first provide broadband Internet services for users. In the later stage, we will need to carry out IPTV, VoIP and other value-added data services. This scheme mainly takes into account the access network technology of households, and the commercial, school, and government departments will be adjusted based on actual conditions in the future.

The network built in this network can provide sufficient bandwidth to achieve high-quality data access services and IPTV streaming media services. Networks must have excellent scalability and upgrade capabilities to effectively support the three-in-one business needs in the future.

Residential broadband access network solution

This solution will be used for new projects to build residential broadband using SALIRA 2550 OLT and SALIRA 3300 series ONU, the system fully guarantees and comprehensively considers reliability, standard applicability, security, scalability, SLA & QoS, and manageability, this platform is used to effectively develop data access network technology and IP-based voice, data, and video services.

Network Topology

A total of 248 buildings and 690 residential units are built in seven standard sections in the Community, with a total of 9108 households. There are also several commercial, school, and government buildings. Due to the large number of residential buildings, this scheme mainly takes into account the residential access network technology. The access network technology problems of commercial, school, and government institutions in the future can be adjusted according to the actual situation.

Local OLT configuration Scheme

Considering the large number of users in the residential area, this design uses the SALIRA telecom-level central station device OLT2550, which is a 10U design with a plug-in structure and is planned to be installed in the Central Data Center of the residential area. 28 downstream PON optical ports and 28 upstream GE ports are available in full configuration. The OLT can provide a maximum access capacity of 28 Gbps. This satisfies the broadband access network technology of the residential area and the needs of IPTV services in the future.
