A layer of cladding, consisting of silica with lesser purity, envelopes this core and serves to confine the light within due to its reduced refractive index. A protective layer envelops the cladding to absorb impacts and guard against impairment. Good quality fiber laying and termination systems help achieve minimal back reflection and low signal loss. They also feature resistance to moisture, impact, chemical exposure. Since outside plant fiber optic networks can cover a broad range of installation types using varied components over different types of geography, it is impossible to cover the specifics of any one installation. This chapter should provide an overview of the various options available in OSP. To address this problem, the fiber termination box (FTB) was created to protect the fragile fiber terminals and provide a simple and clear way to manage the incoming and outgoing cables. Fiber optic cable markers identify fiber optic cable runs and the.
