Detailed explanation-1: -D. Explanation: circulator is a device used in electromagnetic theory. all others are optical components.
Detailed explanation-2: -One form of cabling supported by Ethernet is fibre optic cable. This type of cable is expensive to purchase and difficult to install. Its primary use is to interconnect buildings and to connect equipment which is too remote for connection using other types of cabling (e.g. 10B5, 10B2, or 10BT).
Detailed explanation-3: -Multimode fiber is more commonly used in LAN backbones within buildings. Multimode fiber uses LEDs as the light source, while single-mode fiber generally uses laser light sources. Furthermore, single-mode fiber is typically more expensive than multimode.
Detailed explanation-4: -Fiber-optic cables Also known as optic cables or optical fiber cables, they transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables.
