Of course, using fiber is not a trivial exercise. For engineers and installers whose experience and expertise are only with coax, there's a new world of optical-cable specifications, the fiber plus the protective jacketing, optical connectors, bend radius, E/O converters and components, and more. In addition, it's often makes sense to run a fiber-optic cable assembly which has unused fibers inside for additional capacity in the future, known as dark fiber. In contrast, running extra coax in parallel with the in-use coax is much more costly and occupies much more space.
Have you ever wished you had a performance- and cost-effective alternative to coaxial cable? Have you explored using analog fiber for RF? What concerns and issues would you have from a technical as well as personal standpoint?
