Why Fiber Optic?

SmartAVI has created a full line of fiber optic extender products, 

understanding that this technology is superior to traditional 

cabling. 

Fiber optic cables are:

• 

capable of transmitting over very long distances with no 

signal loss.

• 

immune to electromagnetic interference. In situations where 

there is considerable interference, fiber optic cabling is the 

only solution. 

• 

much more secure because they cannot be easily tapped.  

For this reason, military and law enforcement agencies use 

fiber optic cables for the transmission of sensitive data.

• 

relatively inexpensive and small enough to be routed 

through small spaces.
