Fiber optic cable laying can share power pole lines
All-Dielectric Self Supporting (ADSS) cables can be erected in close proximity to power transmission lines. This of course, allows for pole sharing, which of course, reduces installation costs and speeds-up deployment. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both. Fiber in a duct solutions have a major aesthetic. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. The charter of the FOA was to promote professionalism in fiber optics through education, certification, and. One way round this is to install aerial fiber cables close to power lines, such as on mixed use poles which also carry electricity. Obviously, these fiber cables need to be resistant to electricity, which can be difficult as many aerial cables contain high tensile steel (HTS) for tensile strength. 4. FO-VC2 JOINT USE - VERICAL MIDSPAN CLEARANCES 48. Utilities began using fiber optics almost as soon as it became available.
