Fiber Optic and Telecom Underground Services

We provide end-to-end underground telecom services — trenching, conduit installation, cable pulling, and site restoration. Whether your project is a single-property fiber run or a multi-block municipal telecom upgrade, our crews have the equipment and experience to execute it efficiently.



Our fiber optic and telecom services include:


  • Fiber optic trench excavation
  • Direct-buried fiber optic cable installation
  • Underground conduit and innerduct installation
  • Micro-trenching in urban environments
  • Vault and handhole excavation and installation
  • Telecommunications infrastructure installation
  • Joint trench coordination with other utilities
  • Full site restoration including asphalt and concrete repair


Who We

Work With

We regularly complete fiber optic and telecom underground work for:


  • Internet service providers expanding last-mile connectivity
  • Telecom contractors on municipal and commercial contracts
  • General contractors coordinating joint utility installations
  • Property developers running fiber to new construction
  • Cities and municipalities upgrading public communications infrastructure


If your project requires coordinated trench work across multiple utility types, we can open a single joint trench to accommodate fiber alongside gas, electrical, or other conduit runs — reducing total excavation cost and site disruption.

Our Fiber Optic Process

Site Assessment

We begin with a full site review covering soil conditions, access points, existing utility locations, and all depth and width specifications required by your project plans. We identify potential conflicts early and build a clear plan before any equipment hits the ground.

Utility Marking and Potholing

Before we dig, we coordinate with 811 and perform vacuum potholing at key locations to verify the exact position of existing underground utilities. This protects what's already in the ground and keeps your project on schedule.

Precision Excavation

Our operators trench to exact specifications — precise depth, consistent width, clean sidewalls. We work efficiently in open areas and tight urban job sites alike, with equipment scaled to each location.

Underground Telecom Installation

Our licensed crews install conduit, innerduct, and fiber optic cable to project specifications and all applicable California and LA County code requirements. We coordinate directly with your telecom contractor or utility provider throughout installation.

Backfill and Restoration

Once installation is complete we backfill, compact, and fully restore the surface. We match or exceed original site conditions including asphalt and concrete repairs where required.

Frequently Asked Questions — Fiber Optic Trenching and Telecom Installation in Los Angeles

  • How deep does a fiber optic trench need to be in California?

    Most fiber optic installations in California require a minimum trench depth of 18 to 24 inches for direct-buried cable, and 24 to 36 inches for conduit runs depending on location and project specifications. We trench and install to whatever depth your plans require.

  • Do you handle both the trenching and the fiber optic installation?

    Yes. We provide complete underground telecom services including trench excavation, conduit installation, fiber optic cable installation, and full site restoration — all under one contract.

  • How long does fiber optic trenching and installation take?

    Timeline depends on trench length, soil conditions, site access, and installation scope. A typical residential or small commercial run can be completed in one to two days. Larger municipal or multi-block projects are scoped individually.

  • Do you handle permits for fiber optic projects in Los Angeles?

    Yes. We manage permit applications with local authorities and coordinate with utility companies before breaking ground on any project.

  • Can you install fiber optic and other utilities in the same trench?

    Yes. Joint trenching for fiber alongside electrical conduit, gas, or other utilities is common and reduces overall excavation cost and site disruption.

  • Do you offer emergency fiber optic trenching in Los Angeles?

    Yes. We maintain rapid-response crews available for urgent trench and installation work across LA County.
