以太网通讯能否使用光纤线

我们已经知道了，使用上面的这东西可以与电脑端进行网络通讯，那么，我们不用普通网线，而是用

“光纤线”可以么？为了传输距离更远。

28j60不能直接接光纤。。。
你自己买一个光猫吧。。。然后再用网线接28j60

光纤只是一种通信介质

最终端还是RJ45头

只要是网络，你最终接口都得是RJ45的，你这光纤我怎么觉得像是音频光纤线啊！

不是吧，光纤传播的是电？

你还是弄清楚什么是光纤吧

两端加光纤收发器

百度截图的，哈哈，家里有光纤线，好小的，就是觉得做个系留的，通过光纤通信。

---------------------------------
An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.[1] Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with lesser amounts of loss; in addition, fibers are also immune to electromagnetic interference, a problem which metal wires suffer from excessively.[2][2] Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces, as in the case of a fiberscope.[3] Specially designed fibers are also used for a variety of other applications, some of them being fiber optic sensors and fiber lasers.[4]
