Epon Terminal Equipment The Onu Development,

EPON (Ethernet passive optical network) technology is a new kind of fiber optic broadband access network technology, which is according to Gbit. It inheritted the low cost of Ethernet and the high bandwidth of light network,,so it is the most effective solution of FTTH. The EPON business is also the most effective solution to solve the information superhighway "last kilometer". On the product appearance, the EPON system mainly include OLT, ONU and EOC. This paper mainly studies ONU which is the terminal equipment of EPON, it is an important part of the EPON system. The paper introduces the design of hardware and software ONU design, testing and system application.Main contents:1. The principle and development situation of EPON.2. The Study background and meaning of Optical Network Unit.3. EPON ONU terminal is studied system design.4. The study EPON terminal ONU hardware design and software design.5. A study of the test and EPON ONU terminal system application.Develop after continuing of the last few years, the EPON item grows profusely and quickly now, and a great deal of the domestic EPON item appear. The success of EPON terminal equipments ONU, can perfect my company have EPON product line and raise the level of company development team. Because the EPON series product adopts international domestic more leading of fiber optic connection technique, the customer who mainly face is a province, city one class network company, the proportion of the function and price of product is perfect, so it will definitely have good economic efficiency and extensive social efficiency.
