Fiber optic conduits provide fiber optic cables with superior protection and versatility. These conduits are widely used in various industries and employed in many applications. Many companies use these conduits for their numerous benefits to set their cables up for long-term success.

As you consider using fiber optic conduits, find out more about what they are and how they differ from other types of conduits. Additionally, you’ll learn more about the benefits of fiber optic conduits and the various kinds you can choose from.

What Is a Fiber Optic Conduit?

Fiber optic conduits are a kind of fiber optic protection tubing that surrounds individual fiber strands to keep them safe and secure. These conduits house fiber cabling, providing some of the most critical pieces of infrastructure for a network or device.

 

What Makes Fiber Optic Conduit Different Than Other Types of Conduit?

Fiber optic conduits provide the best security and protection around for fiber optic cables. Often, more traditional conduits mostly consist of polyvinyl chloride (PVC) and other nonmetallic materials. In contrast, fiber optic conduits are primarily constructed of steel or metal, with PVC or fiberglass braiding occasionally incorporated as well.

fiber optic conduits provide the best security and protection around for fiber optic cables

Conduits made out of nonmetallic materials or PVC can protect traditional cables from damage, but they may not provide the amount of protection you require for your fiber optic cable. For instance, PVC conduits can work for overground applications that don’t require a great deal of protection, but they’re not as well-suited for underground applications. That could put your fiber optic cables in danger.

Since you’ll be investing in fiber optic cables and will rely on them for your network, you’ll likely want a greater deal of protection for them. Fiber optic conduits are designed specifically to house fiber optic cables in the toughest environments. As a result, these conduits put significant distance between themselves and more traditional conduit options regarding their durability and protection.

When you choose fiber optic conduits, your fiber cable is protected from corrosive soil, accidental excavation and rock damage. These conduits also offer superior protection from damage due to severe weather conditions and temperature changes. Since they can be buried underground, fiber optic conduits don’t need as much maintenance as aboveground models, such as aerial conduits.

If you’re worried about using metal conduits due to the danger of electricity being conducted through cables, you don’t have to worry about this for fiber cable conduits. Unlike other cables made of copper and aluminum, fiber optic cables transmit digital binary signals and not electrical current. This lack of an electric current is one of the primary reasons that fiber conduits can be made of metal, as there’s no danger of being shocked by them.

Benefits of Fiber Optic Conduits

If you’re interested in purchasing conduits for your cables, fiber optic models are an excellent decision to make. They provide exceptional flexibility and protection to ensure cables are safe from damage. They also can be utilized in many applications and are very safe to perform maintenance on.

Check out some of the top advantages of using fiber optic conduits below.

Protection

You probably want your network to stay secure and your fiber optic cables to stay free from damage. Fiber optic conduits do just that. They’ll house your cable, protecting it from potential danger. The conduits can come in various materials like stainless steel, galvanized steel, flexible metal, PVC sheathing and fiberglass braiding. These materials provide a significant amount of protection for your cables and keep them safe in underground and aboveground applications.

As a result of the different materials you can choose from for your conduits, you can find a conduit that protects against specific types of dangers. For instance, you can choose a conduit designed to protect against impact and abrasion, or you might select one that can also protect against gases, abrasions and extreme temperatures. You can even find conduits resistant to seawater, oils and acids, allowing you to place your cables in the toughest conditions while keeping them safe with the conduit.

Flexibility

Rigid conduits that can’t be adjusted to fit your fiber optic cables’ needs can be too restrictive and harm your ability to set up your network. Rigid conduits can also be a problem for opto-electronic applications, as they may need to fit the unique shapes of machines and instruments.

Conduits need to be flexible enough to handle unforeseen challenges and varying shapes. Fiber optic conduits do just that, as a supplier can outfit them with flexible metals that can be adjusted to a company’s unique requirements. Due to this flexibility, fiber optic conduits are a great choice for many applications and environments.

Safety

Since fiber optic cables don’t conduct electricity, conduits that utilize metal are much safer. In traditional copper wires that conduct electricity, a metal conduit could lead to shocks and other worker injuries. With fiber optic conduits that house fiber optic cables, you get the benefits of metal’s superior protection and durability while also being exceptionally safe. Those who come into contact with fiber optic conduits don’t have to worry about getting shocked, and they can focus solely on performing maintenance or other tasks.

Versatile Applications

One of the major benefits of fiber optic conduits is their many applications. They’re regularly utilized by opto-electronic instruments that serve the industrial, transportation and medical fields. For instance, their temperature resistance allows them to be used in thermocouples, which measure high temperatures in laboratories and industrial facilities. Additionally, the medical industry uses them with devices that go into the body to protect fiber cables from bodily fluids and blood.

Their durability also makes them perfect for devices that need to be reliable, such as wheelchairs and sensors. Fiber optic cables are also regularly employed by the telecommunications industry to assist with modern network infrastructures. The conduits’ durability allows you to safely install data lines underground, as they offer moisture, pressure and abrasion resistance.

Durable

When a conduit degrades quickly, your cables and wires can be exposed to dangers that could lead to damage. Conduits that degrade quickly or are easy to damage can cause networks and machinery to go down when you need them most. Additionally, a company can be stuck with higher repair costs as they have to fix their conduits and cables consistently.

With fiber optic conduits, you can expect them to last a long time and keep your wiring and cables safe. This protection means your networks and machinery can work without interruptions or damages. You can also save on expenses, as you won’t have to devote staff for repairs or pay for replacement conduits or cables as often. The durability of fiber optic conduits set them apart from others and makes them an excellent choice for many companies.

Fiber Optic Conduit Specifications

There are many fiber optic conduits on the market for different purposes, which allows companies to find the right model for their needs.
