Telecom Project Overview

Whether it be an urban or rural setting, we all depend on reliable internet and mobile connection. Within 20 years, the commodity has become a necessity - now found in most households and neighborhoods.

With the scale of communications growing, a need for larger broadband capacity emerged, a headache solved by fiber optic cable. Fiber optic cable transmits mega amounts of information at record speeds but requires the utmost protection from telecom conduits to do so. To protect the cabling, telecom conduit structures must be durable, resistant to chemicals and corrosive soils, and function in the most extreme environments.

With its unmatchable qualities, epoxy fiberglass is the runaway conduit choice for networking operating companies looking to protect their fiber optic highway. FRE® Below Ground Conduit system products are used the world over by power and telecommunications utilities as an economical and long-lasting alternative to other types of conduit. Fiberglass is a revolutionary fully weatherproof material, capable of handling harsh temperatures, making it usable even in extreme environments such as the Arctic!

Fiberglass Conduit Types for Telecommunication

The Below Ground Fiberglass Conduit range is designed for encased burial and direct burial applications. To determine which conduit is best for your telecommunication project, pay attention to the wall thickness.

Thin Wall conduits are built with reduced nominal wall thickness recommended for encased burial telecom projects. Heavy Wall conduits are constructed with heavier nominal wall thickness, making them capable of handling the additional compression of direct burial telecom projects. Standard Wall conduits, the in-between, can be used for encased burial and direct burial, depending on the specifics of the project.

If you are searching for something different, our Below Ground Fiberglass conduits can be designed to meet specific requirements, including wall thickness and offset elbows. Submit a request today, and we’ll accommodate conduits to match your project.

Benefits of Below Ground Fiberglass Reinforced Epoxy Conduit

For telecommunication projects, the Below Ground Fiberglass Reinforced Epoxy Conduit has a range of advantages over other commonly used conduits.


The lightweight nature of epoxy fiberglass conduit (considerably less than PVC or steel) enables big cost savings through reduced system weight, reduced assembly time, reduced freight charges, and lower support costs.

Temperature range

FRE® conduit can withstand temperatures ranging from -40°F to 230°F, meaning that even in the coldest and warmest temperatures, the conduit maintains its unique characteristics - something that PVC cannot do.


Conduit contains no chlorine, halogen or other toxic materials, unlike PVC, which can release toxic bromine or chlorine.

Flexible and enduring

Epoxy fiberglass conduit is flexible and enables it to conform to even the most uneven surfaces.

Cable fusion

While steel conduit will weld with cable and PVC conduit may fuse or melt under electrical fault conditions, you will not witness Cable Fusion in FRE®.

What About Encased Burial Projects?

There are several reasons why a telecom conduit bank could be concrete encased. Often, it provides additional strength for future loads, but it can also protect the bank from accidental dig-ins during excavation.

The difference between conduits for encased burial and direct burial is wall thickness. Direct burial conduits are thicker to handle the extra compression, but all other characteristics are identical. When undergoing an encased burial for a telecom project, Thin Wall or Standard Wall conduit systems are recommended - the reduced weight enables extra savings through assembly time and freight charges.

At FRE Composites, we have both Encased Burial and Direct Burial products for application.
