Fiber, cable, low voltage, and telecom contractors need more than a generic contractor policy. Different scopes trigger different coverage requirements — an OSP directional drilling crew has entirely different risks than a splicer working inside a data hall or a drop-install tech running fiber to residential homes. Below is the complete list of coverage lines that fiber, cable, and telecom contractors actually need to bid ISP, carrier, and hyperscaler work — with what each one does, when it’s required, and how it fits into your total insurance program.
Core Coverage — Required on Every Job
Every fiber and cable contractor working on a subcontract needs these four core coverages. These are the minimum for ISP prime, carrier (Zayo, Crown Castle, AT&T, Verizon, etc.), and commercial GC pre-qualification.
Third-party bodily injury and property damage arising from your operations. The foundational coverage on every COI. Typical requirement: $1M / $2M / $2M with Additional Insured, Waiver of Subrogation, and Primary & Noncontributory endorsements. See 7 required COI endorsements →
Medical care and lost wages for employees injured on the job. Required by every state (rules vary — California requires it at 1 employee, Texas is voluntary but hyperscaler GCs reject non-subscribers). Class codes 7600 vs 6325 matter for pricing accuracy. Workers’ comp state guide →
Bodily injury and property damage arising from company vehicles — work vans, box trucks, bucket trucks, drill rigs, splice trailers. Typical requirement: $1M CSL with Owned, Hired, and Non-Owned coverage. Long-distance crew travel between metros makes Hired & Non-Owned auto essential for multi-state operations.
Additional liability limits above your GL and Auto. Typical requirement: $2M–$10M. Zayo requires $5M umbrella minimum. Hyperscaler GCs (DPR, Turner, Skanska) often push to $10M. Umbrella pays after the underlying policy exhausts — critical for large-loss underground utility strikes.
Underground / OSP-Specific Coverage
If you run directional drilling, trenching, boring, aerial or underground splicing, or any OSP construction, you need these coverages that go beyond the GL — because your GL does not cover them. These are frequently the difference between a paid claim and a denied claim.
Underground utility strikes that release gas, sewage, fuel, or drilling fluid — the environmental piece your GL does not cover. Frac-outs. Directional drill hits on gas mains. Sanitary sewer breaches. This is the coverage that pays cleanup, remediation, and third-party pollution claims. Full pollution liability guide →
Coverage for fusion splicers ($15K–$30K each), OTDRs, MPO test gear, cable reels, and equipment in transit or at unattended job sites. Standard property policies exclude this. Essential for splicing crews carrying six-figure test kits.
Covers materials you’re installing until the customer accepts them — fiber cable, conduit, hardware, ONTs. Bridges the gap between when material is delivered to the job and when it’s formally accepted. Critical for long-duration OSP builds.
Coverage for rented bucket trucks, mini-excavators, boring machines, and other equipment you don’t own. Rental companies require this — and your standard GL does not cover physical damage to the rented gear.
Prime-Specific & Specialty Coverage
Depending on which prime contractors and end-customers you work for, you may need one or more of these specialty policies. These are what Zayo’s Avetta prequalification triggers, what hyperscaler GCs require on data center builds, and what BEAD-funded projects mandate.
Third-party cyber claims arising from your access to customer networks, systems, or data. Zayo requires $5M cyber via Avetta’s Universal Insurance Questionnaire trigger. Hyperscaler and enterprise scopes increasingly require it. Not covered by GL. Avetta compliance guide →
Errors & omissions for design, engineering, network commissioning, or as-built documentation errors. Often required for BICSI-credentialed splice work involving certification of installed infrastructure. Not covered by GL.
Wrongful termination, discrimination, harassment, wage/hour claims from employees. Recommended for any contractor with W-2 employees. Not covered by workers’ comp.
Performance and payment bonds for BEAD-funded projects, prime contracts with hyperscalers, and public works. State licensing bond required in California ($15K CSLB), Arizona (varies), and other states as a condition of licensure.
Building the Right Program for Your Operation
Every fiber and cable contractor’s coverage stack is different because the operations differ. Here’s how the program shapes up by scope:
| Your Operation | Required Core | Must-Add Specialty |
|---|---|---|
| Splicing & termination only (inside plant, splice cans) | GL / WC / Auto / Umbrella | Inland Marine (splicers & OTDRs) |
| Aerial fiber & drop install | GL / WC / Auto / Umbrella | Inland Marine, Rented Equipment |
| Underground & directional drilling | GL / WC / Auto / Umbrella | Pollution Liability (CPL), Inland Marine |
| Data center & hyperscaler fiber | GL ($2M+) / WC / Auto / Umbrella ($5M+) | Cyber Liability, Professional Liability, Pollution Liability |
| Zayo / Crown Castle / carrier fiber construction | GL / WC / Auto / Umbrella ($5M+) | Cyber Liability ($5M), Pollution Liability, Inland Marine |
| Full-service (all of the above) | All core with $2M/$4M GL, $10M umbrella | All specialties + Bond capacity |
