2、Consider a 30-km long optical fiber that has an attenuation of 0.8 db/km at 1300nm.If 200uW of optical power in launched into the fiber,let us find the optical output power Pout(out为下标).
Please explain the loss mechanisms simply in the fiber.

这种问题都是光纤通信的基本问题.
问你200uW的光功率入射到损耗为0.8dB/km,长度30km的光纤,输出功率是多少.
这种问题随便找一本光纤通信的书都可以搞定的.
