Single-mode and multi-mode fiber backbone systems for commercial buildings, campuses, and industrial facilities — fusion spliced, OTDR tested, fully documented, and built for the bandwidth demands of modern operations.
Copper gets you to the desk. Fiber connects the building. Backbone fiber is what moves data between telecom rooms, between floors, between buildings — and when it's installed right, it lasts the life of the facility without a second thought.
TCSS installs single-mode and multi-mode fiber optic systems for commercial buildings, education campuses, industrial facilities, and government properties across North Carolina and the Southeast. Our fiber techs are experienced in fusion splicing, enclosure termination, OTDR testing, and documentation — everything from the conduit pull to the final test report.
Whether you're building out a new facility, upgrading an aging copper backbone, or connecting multiple buildings on a campus, TCSS designs and installs a fiber system that serves the building's needs today and scales with its demands tomorrow.
Both have their place. Here's how we help you decide.
Single-mode fiber carries light over much longer distances — up to kilometers — with virtually no signal loss. It uses a smaller core (9µm) and a laser light source, making it ideal for campus backbones, building-to-building runs, and any application where distance or future bandwidth is a concern.
Multi-mode fiber uses a larger core (50µm) and LED light source, making it easier and less expensive to terminate and test. It performs well for distances up to 300–400m at 10GbE, making it the right choice for floor-to-floor backbone runs in most commercial buildings.

Fusion splicing joins fiber strands with near-zero signal loss — the gold standard for backbone and long-distance fiber. Our technicians perform fusion splicing on all fiber types including single-mode, multi-mode, and ribbon fiber. Every splice is protected in a splice enclosure and documented with loss readings.
Every fiber run is tested bi-directionally with an OTDR (Optical Time Domain Reflectometer) — identifying splice loss, connector loss, bend radius violations, and any faults in the fiber path. Results are documented in a full test report that becomes part of the turnover package handed to the building owner.
Fiber terminations are housed in wall-mount or rack-mount enclosures installed cleanly in telecom rooms. Patch panels are labeled, pigtail splices are organized in splice trays, and slack is managed properly so the enclosure can be accessed and serviced without disturbing the fiber bundle.
Vertical fiber connecting MDF to each floor's IDF — the central nervous system of a multi-floor commercial building.
Direct-buried or conduit-run outdoor fiber connecting multiple buildings on a campus or industrial complex.
High-density fiber infrastructure connecting network equipment in data rooms and server environments.
Campus-wide fiber backbone connecting classrooms, labs, admin buildings, and athletic facilities.
Fiber infrastructure in manufacturing and warehouse environments where copper EMI interference is a concern.
Upgrading aging copper backbone to fiber — or replacing damaged or underperforming existing fiber runs.
We review drawings, confirm fiber type and strand count, identify conduit routes, and flag anything that needs resolution before mobilization.
Conduit, innerduct, or cable tray installed to protect fiber runs — coordinated with other trades to avoid conflicts.
Fiber pulled with proper bend radius protection, fusion spliced at all transition points, terminated at enclosures on both ends.
Every run tested bi-directionally. Full test report, splice log, and as-built documentation delivered at turnover.
Upload your drawings and specs — we'll review the fiber scope, confirm strand counts and types, and return a complete bid. Single-mode, multi-mode, campus backbone, or building-to-building — we do it all.
