Fiber Optic Cable Installation
Precision trenchless bores for ISPs, telecoms, and FTTH rollouts — connecting Carolina neighborhoods to high-speed internet.
Sloan Underground Construction has been installing outside-plant fiber optic infrastructure across the Carolinas since 1965. We subcontract for internet service providers, telecom companies, and FTTH projects — pulling HDPE duct, direct-bury cable, and multi-duct bundles on residential, distribution, and backbone routes. Most residential drops finish in hours; longer distribution runs on accelerated multi-day schedules.
How fast can you bore fiber in the Upstate?
A typical residential drop (150–400 feet) finishes in hours. Distribution and backbone runs take 1–3 days depending on length and obstacles. Our JT-series fleet reliably hits 300–600 feet of bore per day in typical Piedmont clay and mixed soil.
Your Fiber Subcontractor in the Carolinas
We work from your engineering plan or draft one with you. Conduit sizing, depth, slack-loop locations, hand-hole positioning, and splice enclosure placement are all on our standard job sheet. We coordinate directly with your project manager or lead engineer so the bore schedule matches the cable-pull and splice windows.
Common installs: 1.25-inch, 2-inch, and 4-inch HDPE duct; direct-bury aerial conversions; multi-duct backbone bundles; service drops; campus distribution; and road crossings under state or municipal right-of-way.
How a Fiber Bore Runs
-
01
Plan Review
Walk the route, confirm conduit sizing, depth, hand-hole positions, and splice enclosure locations with your engineer.
-
02
811 & Right-of-Way
Call Before You Dig; verify all existing utilities; confirm right-of-way or road-crossing permits.
-
03
Bore & Pull Duct
Drill the pilot, ream, pull HDPE duct or multi-duct bundle through to the exit. Maintain planned slack loops.
-
04
Handoff & Restoration
Cap and tag duct, set hand-holes, restore the site, and hand off to the fiber splice crew.
Fiber Projects We Handle
- FTTH service drops — 150–400 ft residential fiber to the home.
- Distribution routes — neighborhood-level fiber distribution.
- Backbone runs — high-count count fiber trunk conduit with multi-duct bundles.
- Road crossings — state or municipal right-of-way bores.
- Campus & commercial — office parks, schools, warehouses, hospitals.
- Aerial-to-underground conversions — moving overhead fiber underground.

Do you subcontract for ISPs?
Yes. We regularly subcontract for internet service providers, telecom companies, and FTTH build-outs across the Carolinas. Our scope is the outside plant bore work: conduit placement, direct-bury pulls, and duct system installation.
What diameter conduit do you install for fiber?
1.25-inch, 2-inch, and 4-inch HDPE duct are common. Multi-duct bundles for backbone and distribution. We work from your engineering plan or draft one with you.
Can you bore under roads and driveways for fiber?
Yes — that's where HDD pays off most. We bore cleanly under roads, driveways, parking lots, and waterways, avoiding the permit complexity and disruption of open-cut.
How fast can you bore fiber?
Residential drops run 150–400 ft and finish in hours. Distribution and backbone runs vary; we hit 300–600 ft per day in typical Piedmont soil.
