What Limits the Optical Transmission Distance
Fiber optic network is gradually replacing copper network, because of its various advantages, like high speed, high density and high bandwidth, etc. Among which is that fiber optic cable can support much further distance than that of traditional copper cables like coax cable or twisted pair wire. However, in practice, the exact distance that fiber optic can support are limited by many factors. Transmission distance has become one of the biggest problems in the super fast optical communication. On one hand, with the expansion of the fiber optic network, distances for the optical links span meters to hundreds of meters and even kilometers. On the other hand, optical signal becomes weak over long distance. Stuck in this dilemma, many components and methods are being used to break the limitation of the transmission distance. This article will focus on the main factors that limit optical transmission distance. Fiber Optic Cable Type Generally, the maximum transmission distan...
