In summary, the basic parameters of the transmission characteristics of optical fiber lines are attenuation, dispersion, and nonlinearity. Alongside aspects such as wireless (WiFi and Cellular) infrastructure and structured cabling infrastructure design; it's important that infrastructure professionals understand fiber optic products to create more productive and. We have put together five parameters worth considering when selecting optical cables. While selecting fiber optics cable, it is important to match up the speed of transmission. Not included are many proprietary designs.
