Detailed explanation-1: -Because many WAN connections need high data rate links between service providers based in different countries, fibre optics are commonly used.
Detailed explanation-2: -The two main types of fiber optic cables are single-mode and multimode. Multimode fiber has a larger core, which allows multiple light signals to be sent simultaneously. This results in a higher bandwidth than single-mode fiber.
Detailed explanation-3: -Fiber optic cables are commonly used because of their advantages over copper cables. Some of those benefits include higher bandwidth and transmit speeds. Fiber optics is used for long-distance and high-performance data networking.
Detailed explanation-4: -Fiber optic internet speeds are about 20 times faster than regular cable at 1 Gbps. Why is fiber optic cable internet so much better than plain ol’ cable internet? Because there’s no copper wire to gum up the works. Cable internet sends its signals down metal wires.
