•Fiber does not conduct electricity. It is not affected by heat and cold. It has a longer lifespan than copper or coax. It has virtually unlimited bandwidth.

•The closer to the home that fiber is pulled, the more bandwidth opportunity there is for the end user. 

•Fiber has a higher bandwidth capacity and can easily transmit traditional applications such as phone, broadband internet, and digital tv with plenty of capacity left over for other advanced applications in the future.

•Data on a fiber optic cable can travel many miles in a split second.  This speed allows a more cost-effective method to transmit large amounts of data to everyone’s homes. 

•Several miles of fiber optic cable can be made cheaper than equivalent lengths of copper wire.

•Voice and data transmissions via fiber optics are more secure than when they are sent over conventional copper cable connections.

•Once installed, fiber is usually upgraded by changing the electronics that creates the light pulses, and not by replacing the cable itself.  That’s why fiber networks are said to be “futureproof.”
