Territory: Michigan, Indiana, Ohio & Illinois
OSP Materials is a manufacturers representative for outside plant and telecom materials, based in Caledonia, Michigan. We support contractors, utilities, and broadband providers across Michigan, Indiana, Ohio, and Illinois — helping specify and source fiber pathways, locating systems, optics, and related OSP materials for builds in the Great Lakes region.

Where we work
We cover four states with the same local, manufacturer-rep approach:
- Michigan — Home base in Caledonia. Fiber, broadband, and utility OSP support statewide.
- Indiana — Contractor and provider support for fiber and telecom builds.
- Ohio — OSP materials and application guidance for Midwest network projects.
- Illinois — Full OSP Materials coverage for quoting and project support.
Whether the job is a rural broadband extension, a metro fiber build, or plant upgrades, we bring manufacturer expertise into your territory and coordinate the line card so specs and sourcing stay clear.
