What are the benefits of fiber-optic cabling?
What will be an ideal response?
Fiber-optic is capable of much higher bandwidths. Fiber-optic cabling is immune to EMI and RFI so it has no problem with interference. It also has no leakage so it is highly secure, almost impervious to eavesdropping. Because of low attenuation, fiber-optic cable can travel greater distances at a higher bandwidth.
