Which one among the following transmission media is best suited for transmission of information over large distance?
general-scienceinformation-technology
- ATwisted pair
- BOptical fibre
- CThick Ethernet
- DThin Ethernet
Explanation
Optical fibre carries signals as light with very low attenuation and huge bandwidth, making it the best medium for long-distance transmission. Twisted pair and Ethernet variants (thick/thin) suffer higher loss and are suited to short local links. Hence option B is correct.
