请问以太网通讯是否能使用光纤线？

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]
维基百科说的

已经了解了，谢谢

老大，是不是搞两个这样的东西就好了？但是先前的网线接法是交叉的网线也没关系是吧？

你看下我下面的截图的回复，是不是这样就可以了？

应该可以
