The Fiber Optic Network Specialists - Since 1994


When it comes to Fiber Characterization testing, we wrote the book on it. Really, we literally wrote the book, just take a look below. Our crews are highly skilled professionals that travel throughout the United States and beyond to provide our clients with a dependable staff and reliable results. Sure, a strong argument can be made that we'll save you money. But, that's not what is important is it. What is important is to find a company with experience and character to do the job right and on time. That, is who we are.

That is what we've been delivering since 1994

We've spliced and tested all types of fiber optic networks. From massive backbones that span the rugged Rocky Mountains, to short laterals that pierce the dark underground tunnels of major cities. We've worked in the desert heat and the freezing snow. We've dealt with spiders and rats and snakes and wasps. We've setup on the tops of poles, the shores of lakes, and the sides of railroad tracks. We've even spliced fibers that were sent to the moon, true story. In short, we can handle any job, anywhere and anytime.


"Where is it?" That is the question that is often asked with respect to a fiber optic network. If you get a cable cut, "Where is it?". If you need to find a splice point, "Where is it?". When you are trying to find the nearest cable to connect to a new lateral, "Where is it?". On and on the question comes up from engineering or operations or accounting or management. When that question can't be answered accurately on a regular basis, we get the call. There is simply no other field audit company that has our breadth and depth of experience with mapping networks. We can not only find your network assets, but we can manage the data and input it into either the software we've developed ( or the software of your choice. Either way, fiber optic networks are our passion. We are the fiber optic network specialists from the dirt to the database.


Advance Fiber Optics, Inc. (AFO) is a privately-held company based in North Salt Lake, Utah under the shadows of the majestic Wasatch mountains. AFO was founded in 1993 with the intent of introducing high standards of aerospace fiber optic engineering practices to the US telecommunications industry. By 1995, AFO founders had successfully achieved their goal and were supporting fiber optic splicing and testing operations throughout the western United States. Those field service offerings continue today, and have expanded to include fiber characterization testing throughout the United States
