一、利用电信级EPON设备实现农村信息化“社会主义新农村建设”是两会中引人瞩目的焦点之一。在新农村建设的过程中,“信息化”是一个极其重要的环节;对电信运营商而言,农村的信息化建设不仅是社会责任,更是商业机遇。目前农民对信息的需求和依赖程度都在日益提高,但与此同时,我们也应看到农村的支付能力仍然处在较低的水平,农村的村落分布也较为分散。所有这些,要求农村信息化所采用的接入方案应具备下列特点:◆覆盖范围广,传输距离长;◆总体造价低;◆扩展性好,有巨大的带宽潜力;
First, the use of carrier-class EPON equipment to achieve rural information “Socialist new rural construction ” is one of the two people’s focus of attention. In the process of building a new countryside, “informationization” is an extremely important link; for telecom operators, the informationization in rural areas is not only a social responsibility but also a business opportunity.

However, at the same time, we should also see that the affordability of rural areas is still at a low level and the distribution of rural villages is relatively scattered. All of these require that the access plan adopted by rural informatization should have the following features: ◆ Wide coverage and long transmission distance; ◆ Overall low cost; ◆ Good scalability and huge bandwidth potential;
