As a fiber optic contractor, you install, maintain, and repair fiber optic cables. Your responsibilities may require you to travel within a local geographic area, to service different sites. Your duties include accessing fiber optics for inspection or repair, whether they are buried or suspended, measuring signal strength, inspecting system performance, and identifying defects. You implement cable placement during construction, splice cables for better service, oversee the design of projects, and communicate with clients to ensure the system meets their needs. A fiber optic contractor works from design to the final product.
