Avondale plans a conduit and fiber backbone program
The city's capital plan includes a Communication Conduit and Fiber Backbone Program for 2027 to 2030, along with a $30,000,000 Pavement Management Program for the same years. Both involve work in the street right-of-way. Schedules in the plan can move.

Call Arizona 811 at least two full working days before digging
Arizona law requires contacting Arizona 811 at least two full working days before digging, and locators have two full working days to respond. Marks must stay visible and valid for 15 working days, so longer jobs need the marks refreshed through 811.

Fiber inside the building follows the same code as copper
Avondale's local changes to the 2023 NEC do not touch the communications articles. Low-voltage work is not on the city's permit exemption list, and we confirm with Building Services at (623) 333-4000 whether your job needs a permit.
When fiber makes sense
Copper network cable stops at about 300 feet, so fiber takes over past that and between buildings. It also carries more data per cable and is not bothered by electrical interference or lightning-induced surges the way copper can be.
- Linking a warehouse to an office across a lot.
- Connecting floors or suites in a larger building.
- Backbone links between switches that carry camera and WiFi traffic.
- A long run to a gate, a sign or a remote building.
Single-mode and multimode
Single-mode fiber carries a signal over long distances and is what most new installs use. Multimode is cheaper for short runs inside a building but limits distance and speed. We choose by distance, by the equipment you have and by where you expect to be in a few years.
Inside runs, outside runs and splicing
Inside a building, fiber runs in the ceiling or in conduit and ends at a patch panel. Between buildings it goes in underground conduit or, where allowed, overhead. Outdoor fiber is armored or gel-filled so water and rodents don't damage it.
We terminate with connectors or fusion splice pigtails, test each strand, and give you the results.
Fiber and your internet provider
A provider's fiber connection ends at a box on your wall, and the provider owns that equipment. We run the cable from that box to your equipment room and set up your own router and switches behind it.
Providers listing Avondale service include Quantum Fiber, Cox Business and Wyyerd Fiber. Buried fiber can be cut, so we recommend a second connection from a different provider or a wireless line.
Digging in Avondale
Any trench for a fiber run starts with Arizona 811. Request the locate at least two full working days ahead, wait for the marks, and dig by hand near them. A long job outlasts the marks, which are valid for 15 working days, so we schedule the refresh before the old ones expire.
Street work is also active around town, including the I-10 and Loop 101 interchange project, so we plan routes and spare conduit before the trench opens.
Often paired with
Fiber usually lands on the structured cabling inside each building, then feeds the switches behind WiFi and security cameras. A backup internet line covers the day your fiber is cut. Call (602) 769-7992 to talk through a route, or see Enzo in Avondale.
