摘要
为了给光纤到户(FTTH)提供一种高速、低价的新方案,本文分别采用波长为1310nm和850nm的收发器,完成了点对点光互联和光接入网的实验,并测量了其传输速率和光接收灵敏度,估算了不同方案的价格.结果表明,用850nm波长光收发器不但保持了1310nm波长原有传输速率,而且价格更加低廉,完全可以达到"最后一公里"的要求.文中对各种方案和性能的优缺点进行比较,验证了用850nm收发器实现FTTH方案的可行性.
Fiber to the home（FTTH） is the direction of the access network. High rate and low cost project is expected The 850nm and 1310nm systems are set to realize Fiber to the Home in this article. Two experiments, optical polnt-to-point connecting and llnk PC up with internet, are finished. Meanwhile, the transmission speed and optical receive sensitivity are measured. The transmission distance and cost are also estimated. Compared with the 1310nm corrmaunication system, 850nm one is cheaper and can also meet the demand of transmission speed. Finally, the performance, advantages and disadvantages of different communication systems are compared. The feasibility of 850nm communication is validated.
