BICSI OSP · Put your knowledge to work in context.
This page supports independent study for the BICSI OSP Designer credential, an outside plant design qualification offered by BICSI. BICSI describes itself as defining "the standards, credentials, and training that ensure systems are designed, installed, and delivered to perform," and its certifications are positioned to "validate expertise to deliver systems that perform." The credential is aimed at professionals who plan, design, and document outside plant telecommunications infrastructure, including route selection, cable and enclosure placement, construction coordination, and conformance with codes and standards. The BICSI OSP case studies are 5 cases and about 3,355 words.
1Right-of-Way Width Versus Easement Width on a Rural Aerial Route
A utility is designing a 6.4 km aerial OSP route along a rural county road to serve a new industrial park. The designer has a 15 m (50 ft) public right-of-way dedicated to the county, but a recorded utility easement only 4.6 m (15 ft) wide centered on the road centerline.
