Detailed explanation-1: -However, fiber optic cables can transmit data over much longer distances. In fact, the differences are vast. Copper cables are limited to lengths of 100 meters ( 330 ft.), per governing standards.
Detailed explanation-2: -Each grade of multimode fiber has a different bandwidth and distance limitation, with OM4 and OM5 providing the greatest bandwidth over longest distance and OM1 providing the lowest.
Detailed explanation-3: -Fibre optic cables transfer data in light form. Hence, option(b) is correct. Fibre optic cable is used for many purposes like computer networking, internet, telephone, etc.
Detailed explanation-4: -Fiber optic transmission is faster Copper-based transmissions currently max out at 40 Gbps, whereas fiber optics can carry data at close to the speed of light. In fact, the bandwidth limits imposed on fiber are primarily theoretical, but have been tested to be measurable in hundreds of terabits per second.
