Although fiber-optic telephone cable is more expensive to manufacture than copper telephone cable, a telephone network using fiber-optic cable is less expensive overall than a telephone network using copper cable. ████ ██ ███████ ██████ █████ ████████ ████████ █████████████ ██ ███████ ██████████ ███████ ██ █████ ████ ███ ████ ██████████ ███████ ███ ██████ ██ █████ ████ ███ ███████████ █████ ███████████ █████ ███ ██████ ████ ███████ ██████ █████████████ ██ ███████
Fiber-optic telephone cables are more expensive to make than copper cable. Networks using fiber-optic cables are less expensive overall than copper. This is because copper cables require frequent amplification of electrical signals to travel long distances, whereas fiber-optic cables use light pulses that travel farther before requiring amplification.
Savings from switching to fiber-optic cables from copper cables exceeds the greater manufacturing cost.
