Fiber Runs
Single-mode and multimode fiber backbone runs between buildings, IDFs, and MDFs across your campus — pulled, terminated, tested, and documented by our own crews.
We design and install fiber backbone runs that connect your MDF, IDFs, and outbuildings: OS2 single-mode for long campus reaches and OM3/OM4 multimode for in-building backbones, in indoor/outdoor, riser, plenum, or armored jacket as the pathway and AHJ require. Crews handle pathway prep, innerduct, fire-stopping at rated penetrations, and proper bend-radius and slack management at each end. Terminations are fusion-spliced into trays or pre-terminated cassettes, then routed to LIUs and patch panels per ANSI/TIA-568 polarity and labeling. Every run is OTDR and insertion-loss tested, labeled per ANSI/TIA-606, and handed over with as-builts so future capacity adds are straightforward.
What's included

- Innerduct, conduit fill, and fire-stopping at rated penetrations per AHJ
- Fusion splicing and termination into LIUs, patch panels, and splice trays
- Slack management, bend-radius control, and ANSI/TIA-606 labeling at each end
- Tie-in to existing structured cabling and network distribution
Deliverables
- As-built fiber pathway and run documentation with fiber counts
- OTDR traces and insertion-loss test results per strand
- Labeled patch panel / LIU port schedule and cable-ID legend
Frequently asked
Should we run single-mode or multimode between our buildings?
It depends on distance and the optics you plan to deploy. OS2 single-mode handles longer campus and inter-building reaches and is more future-proof for higher speeds, while OM4 multimode is common for shorter in-building backbones; we often pull both or extra strands so you have headroom for growth.
Can you add fiber to a live, occupied facility without downtime?
Yes — backbone runs are typically pulled and terminated on new strands, so your existing links stay up. We schedule the brief cutover or splice-in during a maintenance window and coordinate with your IT team so the transition is planned, not disruptive.
How many spare strands should we include in a run?
We size fiber counts to current need plus growth, since the labor to add strands later far exceeds the cost of extra fiber now. A common approach is to specify well beyond today's link count; we'll recommend a count based on your roadmap and pathway capacity.
