  • Understanding Fiber Optic Cable Installation - Fiber Optics Tutorial Series 7 - Fiber optic cable installation is a very special task that only trained professionals can do it quickly and correctly. This is determined by fiber's fragile structure and highly sensitive to microbending and macrobending loss. However, most of the techniques of fiber optic cable installation has been borrowed from those used for copper cables. And currently the majority of fiber cable contractors come from the copper network background. Fiber cables can be divided into two big groups: outdoor cables and indoor cables. Outdoor cables are laid along rights of way leased or owned by telecommunication carriers, and they are well marked after the cables are installed. The telecommunication carriers have their own team of cable installers and they seldom outsource the job to independent contractors. Most independent fiber cable installation contractors install indoor cables most of the time.
