In life, we often see the need for long-distance data transmission in building intelligent projects, basically using fiber-optic transmission. Then, the Inline Closure manufacturer will introduce the difference between fiber and cable. 1. Different nature: The properties of optical fiber and network cable are different, but there are differences in essence. Optical fiber is an abstract concept, which is a transmission rate of dynamic information; and network cable is a medium, which is a carrier of information transmission. 2. the role is different: the role of fiber is to accelerate the transmission of different network information, and the network cable is used to connect devices to improve the efficiency of network information transmission between devices. 3. the existence of different ways: they existed in different ways, the optical fiber exists virtually, there is no physical; and the network cable is a real cable, with a specific physical.
