Advantages of fibre optic line drivers.

For communications within a building or building to building, fibre optic cable is often the medium of choice. It may cost more, but it provides superior-quality data transmission.

fibre optic line drivers offer three main advantages over copper-wire alternatives for communications: superior conductivity, freedom from interference, and security.

Superior conductivity for increased performance—The glass core of a fibre optic cable is an excellent signal conductor. fibre cable yields very low signal loss with proper splices and terminations, and it can easily support data rates of 100 Mbps or more.

Immunity to electrical interference—fibre optic drivers use a nonmetallic conductor, so they neither pick up nor emit electromagnetic or radio-frequency interference (EMI or RFI).

Crosstalk (interference from an adjacent communication channel) is also eliminated, which increases the quality of the transmission.

Signals transmitted via fibre optic drivers aren’t susceptible to any form of external frequency-related interference. This means that fibre connections are completely immune to damaging power surges, signal distortions from nearby lightning strikes, and high-voltage interference. And fibre cable doesn’t conduct electricity, so it can’t create electrical problems in your equipment.

Signal security—Electronic eavesdropping requires the ability to intercept and monitor the electromagnetic frequencies of signals traveling over copper data wire. Because fibre optic drivers use a light-based transmission medium, they’re completely immune to electronic bugging.
