1. EPON Integrated Service Broadband Optical Access System
The EPON integrated service broadband optical access system of Donyan Network Technologies is the emerging all-optical
access network platform, based on the most-advanced EPON technology. EPON technology is a multi-service platform and can
provide services such as data, voice, CATV to meet customers’ various demands. In addition, EPON system is easy to construct,
expand and maintain. It has high network security, reliability and effectiveness. Nowadays with the trend that network and IP
will be mixed together, it has been adopted by more and more operators and corporations. By constructing the two-way access
network based on EPON technology, Donyan Network Technologies can provide high-quality network services and entire
all-optical network solutions which increase our customers great benefits.
Our state-of-art EPON System mainly consists of OLT, ODN optical splitter and ONU endpoint. We own an experienced
research group of EPON technology, a SMT plant and an assembly plant.
The typical network constructure of our EPON system is as follows:
Features of the system platform
� The system uses the most-advanced EPON technology to construct the emerging all-optical access network;
� It has powerful data transportation and multi-service capacity;
� It has many ways for customer isolation so it can provide the most reliable transportation and security;
� The network has favorable compatibility, supports multi-service transportation and has seamless connection with existed
software and hardware of the comstumer;
� Network structure has great flexibility and expandability;
� The system has few potential bug and it is easy to locate the trouble, so it can improve the reliability of the network;
� Central office requires fewer fibers and only a few fiber modules. It is easy for installing and maintaining;
� With high reliability and free maintainance, the PON has great capacity of resisting disturbance. It is also without trouble
about long-distance power and outdoor power.
� The cost of constructing, maintainin, expanding and upgrading is low, which achieves good cost performance.
