Fibre optic
Fibre optic, as in Figure 1.25, is a cable made up of glass through which the light is transmitted. Based on the light transmission, it is offered in two modes:
- Single mode utilizes only one light, and can reach a length from 40 km to 60 km
- Multimode utilizes multiple lights, and can reach a length from 2 km to 3 km.
Apart from its traditional usage in WANs, today fibre optic is used a lot for the implementation of fiber to the home (FTTH), and MAN networks:
