With the development of CATV optical network, the enlargement and perfection of the network system, the optical fiber transmission has extended from the original trunk to different branches and even the buildings and subscribers, which realize the real sense of FTTB and FTTH. And this product is developed in order to adapt to the present domestic and international markets need. The housing is made of aluminum, and the surface is treated with passivation technology. The internal structure is optional regrouped so that the whole machine looks delicate. In the internal electro circuit, the superior patches and components are applied. As to the optical receiving part, the tube core of high performance and exchange rate is used. And low noise amplifying is equipped. Module of high index is used to final stage amplifying output. And also this product can realize bilateral transmission on subscribers' terminal through being equipped with reverse return module, in according users' requirements. In a word, this product is of well-formed appearance, compact conformation, ease of use and superior electric performance indexes, and it is the first choice for constructing large-scale optical fiber network.
