Fiber optics are flexible strands of glass encased in protective coatings that transmit light signals to carry data. This results in faster, more reliable service than traditional copper transmission lines. Most internet service providers use copper lines for the final connections to customers, resulting in slower speeds. Waterloo Fiber’s fiber-optic internet, TV and phone service is 100% fiber and less susceptible to internet outages, interference and damage from lightning and other acts of nature.
