- A fiber optic link is capable of transmitting the entire text of a 30-volume encyclopedia over 100 miles in 1 second!
- Current useful bandwidth up to 10 Gbps carrying 130,000 voice channels (for Single-mode) with repeators needed every 6-15 km(for multimode) and 30-40+ km (for single mode)
as opposed to coaxial: up to 90 Mbps (1,344 voice channels) with repeators needed
every 1-2 km. *
- Fiber optics permit transmission of channels requiring much greater bandwidth than a voice. Television and teleconfrencing require a channel capacity 14 to 100 times that of a digitally encoded voice (896 kbps-6.4 Mbps)!
- Future systems will probably double the highest rate for fibers and reduce the distance between repeators while a similar advance will not occur for coaxial systems.
- Potential useful range to about 1 THz
