This guide explores different types of fiber optic cable, including indoor fiber optic cable and outdoor fiber optic cable, and outlines best practices for installation in different settings. If you're unfamiliar with the fundamental concepts of fiber optic technology, we recommend reading our. Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. These fibers are typically made of glass or plastic and are designed to transmit data over longer distances and at higher bandwidths than other forms of communication cables. CAUTION: Before starting any cable installation, all personnel must be thoroughly familiar with all applicable Occupational Safety and Health Act (OSHA) regulations, the National Electric Safety Code (NESC), state and local regulations, and company practices and policies.
