Radio and television EPON two-way network reform project in a city in Jiangsu Province
A city is a county-level city under the jurisdiction of Suzhou City, Jiangsu Province, and has 9 townships under its jurisdiction. The total number of users is 300,000. This project is an EPON+EOC two-way network reconstruction project to provide data services and two-way interactions for townships and new districts in the main city area. business. Its radio and television broadband access business adopts a mobile cooperation approach. In 2011, it began to develop interactive television services. The approach adopted was IPQAM. Changguang Technology is responsible for providing EPON solutions.

Its radio and television broadband access business adopts a mobile cooperation approach. In 2011, it began to develop interactive television services. The approach adopted was IPQAM. Changguang Technology is responsible for providing EPON solutions.
According to the widespread distribution of its network and the fact that township access is not a high degree of user density, we chose the box OLT equipment C1000, C1500, and C2000 in the front-end equipment room in the solution, and the EPON system has a split ratio of 1:32. The use of a primary or secondary spectrophotometer. The three devices can provide 4, 8, and 16 PON ports respectively, which can be very suitable for this type of network and avoid resource waste.
According to user requirements, the ONU, the EOC head end, and the CATV at the optical node should be integrated in the same information box. One optical node covers 100 units and the coaxial distribution network is passive. With the needs of Zhangjiagang Broadcasting and Television, we quickly developed the industry's first industrial-grade ONU module M3-0400PQ. This module is designed for industrial use. It uses industrial-grade switching chips and industrial-grade optical modules and can withstand -40°C to 85°C. The temperature range, small size and very easy to integrate. After the success of Zhangjiagang Broadcasting and TV, the M3-0400PQ became the standard form of the ONU module in the broadcasting and TV market and was widely used.
The project started in 2008 and is the earliest case of using EPON+EOC technology in China. With its superb technology and "long light is the service" concept, Changguang Technology will continue to follow the needs of users, continuously enrich functions and optimize performance. In addition to custom-developed ONU modules, it has also provided practical functions such as loop detection, MAC address positioning, ONU replacement, and CPU protection, greatly improving the network's ability to operate and maintain, and gaining users' praise.
