The distance of cable transmission has always been a problem asked by weak current installers. Everyone gets along with cables every day. A clear grasp of the application of cables can be used in engineering. Let's familiarize ourselves with common cable transmission distances.

The network cable is the five types of twisted pair cables, and the network cables of different specifications and models have different transmission distances. The network cable is transmitting data signals. If it exceeds the distance that the network cable can bear, the data signal will be attenuated. In severe cases, the data signal will be interrupted.

Category 5 and Category 6 are all 100 meters long, and the reliable oxygen-free copper 6-stranded wire can be up to 120 meters long. If you want to increase the transmission distance, wireless amplifiers can be installed in the middle of 2 sections of Category 5 twisted pairs, and the maximum number can be installed 4 wireless amplifiers. If four wireless amplifiers are installed to connect five subnets, the maximum transmission distance can reach 500m.

The transmission distance of network cables is relatively limited and cannot handle long-distance data information transmission, so optical fibers can be used for long-distance transmission. Optical fibers are divided into multimode fibers and multimode fibers. The transmission distance of multimode fibers is longer than that of network cables, but shorter than that of multimode fibers. In 10mbps and 100mbps Ethernet interfaces, multi-mode optical fibers can be used for a maximum transmission distance of 2000 meters; in 1Gbps Gigabit networks, multi-mode optical fibers can be used for a maximum transmission distance of 550 meters; therefore, multi-mode optical fibers are now used very little.
