Everything Fiber, From Backbone to Repair

Fiber is the backbone of every modern network — and it only performs as well as its weakest splice. We install and certify fiber the way data centers expect it.

Backbone & Riser Fiber

OS2 single-mode and OM3/OM4 multimode backbone between buildings, floors, IDFs and MDFs — engineered pathways and proper bend radius throughout.

Fusion Splicing & Termination

Precision fusion splicing, splice enclosures, pigtails and connector termination (LC, SC, MPO) with loss budgets that pass inspection.

OTDR Testing & Certification

Every strand tested with OTDR and light-source/power-meter, documented and delivered — so you know exactly what was installed and how it performs.

Emergency Fiber Repair

Cut or damaged fiber bringing your facility down? We locate the break, splice and re-certify to get you back online.

Campus & Industrial Fiber

Outdoor-rated, armored and conduit runs between buildings, plus harsh-environment fiber for plants and warehouses.

Carrier & ISP Extensions

Demarc extensions from the carrier handoff to your equipment room, done cleanly and to spec.

Why It Matters

Why Businesses Choose RG Fiber for Fiber Work

  • Certified results, not promises — you receive OTDR traces and test reports for every strand.
  • Design-first approach — we calculate loss budgets and select fiber types before anyone pulls cable.
  • Clean enclosures — properly dressed splice trays and patch panels that make future work painless.
  • Minimal downtime — cutovers planned around your production schedule, including nights and weekends.
FAQ

Fiber Optic Installation FAQ

Should I install single-mode or multimode fiber?

For most new commercial installs we recommend single-mode (OS2) for anything between buildings or with long runs, because it supports virtually unlimited bandwidth upgrades. Multimode (OM4) still makes sense for short in-building runs where equipment optics cost matters. We help you choose based on distances, equipment and budget.

How long does a fiber installation take?

A typical building-to-building or MDF-to-IDF fiber run, with splicing and certification, takes one to three days. Larger campus projects depend on pathways and the number of strands, and we provide a clear timeline with your quote.

Can you repair fiber that was cut by another contractor?

Yes. Damaged fiber is one of our most common emergency calls. We locate the break with an OTDR, fusion splice the damaged section or replace the run if needed, then re-test and document the link.

Do you provide test documentation?

Always. Every strand we install or repair is delivered with OTDR traces and insertion-loss results. If a future issue ever comes up, you and your IT team have a baseline to compare against.
