11 Tips for Installing Fiber Optic Cables

11 Tips for Installing Fiber-Optic Cable in Your Home or Business

Fiber-optic cable is ultra-fast and highly scalable, making it an ideal internet connectivity solution for large communities in 2025 and beyond. It provides reliability and unmatched speed for internet, cable and telephone connections.

If fiber-optic cabling is available in your area, you might see neighbors installing it in their homes or workplaces. You may also see fiber-optic internet becoming more locally accessible thanks to federal funding from the BEAD program, a nationwide initiative to connect all Americans to high-speed internet.

Whether you're a professional in fiber-optic cable installation or a home or facility owner interested in the process, it's important to understand the fiber cable laying procedure. This guide will walk you through the process from beginning to end.

How to Install Fiber-Optic Cable

Before installing fiber-optic cables, check that they're available in the area by contacting the local phone company. They can tell you if fiber-optic is available in the area and where the nearest distribution box is located. The distribution box should be no more than a few hundred feet from the building.

Once you have determined availability, it's time to startinstalling fiber-optic cables. Here's how the basic installation procedure works.

1. Lay Cable to the Building

Contact the phone company to notify them of the cable installation. From there, the technician can lay a cable from the local box to the home or facility. They will set up the cable to run to an optical network terminal on the side of the building. This box is the starting point from which the technician will set up the fiber-optic lines.

2. Plan Your Installation

Get or create a blueprint for the building and plan out the fiber-optic cable setup. Take note of any phones, televisions, computers or other devices that need to be connected to the fiber-optic system. 

Home and business owners should also ensure their devices arecompatible with fiber-optic connections, as some older models are not. If you find that your devices are only compatible with legacy infrastructure, it might be time to replace them with newer models.

3. Clear the Installation Area

Clear out the sections of the wall or ceiling where you plan on running the fiber-optic cable so that you can install it inside the wall. This step may involve coordinating with a contractor or other construction professional to ensure safe working conditions.

4. Run Cable and Conduit

Once the plan and site are set up, the technician can start running the fiber-optic cable from the optical network terminal through the building. 

The cable will be shielded by a rigid or flexible conduit, which is a protective tube or trough through which the cable is fed during installation.

5. Connect Devices to the Internet

As soon as the cable running process is complete, start testing the cable and connecting devices. Be sure to test connectivity as soon as possible to make sure the cable is working properly. Once you have determined that the cable is operating as intended, the construction crew can start installing new drywall to cover the new cable installations.

11 Tips for a Smooth Fiber-Optic Home Installation or Business Setup

No matter where you are installing your optical-fiber cable, there are some universal guidelines to keep in mind. Some of the best fiber cable laying procedure tips are listed below.

1. Thoroughly Plan Your Route

Plan all cable routes before starting to lay cable, and be as detailed as possible. Ensure the cable will not be unnecessarily exposed to hazards. 

If exposure is necessary, installing extra cable protection is critical in high-risk areas. Here are some ways you can protect your cable from the elements:

  • Use certified and rated equipment.
  • Treat cables gently during installation.
  • Leverage raceways and conduits.

In all, conduit runs should not be longer than 100 feet with two 90-degree bends at most. 

2. Install Support for the Cable

Cables should be protected from hanging freely or pressing against sharp edges. Install conduit for support where necessary, especially in cases where the cable may be exposed to stress or subjected to tighter turns.

3. Avoid Overbending the Cable

The minimum bend radius is the smallest radius you can bend a cable without impacting its performance. Typically, the minimum radius is equal to or greater than 10 times the diameter of the cable. 

Take care not to exceed these values or kink the cable, as doing so can damage the cable and cause performance issues.

4. Remove Sharp Conduit Edges

If you are pulling cable in conduit, ensure the interior conduit transitions are smooth. Sharp transitions with edges can damage the cable. When possible, use a flexible conduit to reduce risk to the cable.

5. Remain Within Recommended Tensile Values

Staying within the maximum tensile loading value for your cable is critical for preventing breakage. The maximum tensile loading value, also known as ultimate tensile strength, is the highest amount of stress your cable can withstand before fracturing. 

This measure is different for each cable type, so be sure to check the specifications before installation. If you are ever in doubt of the recommended values or are concerned that you may be exceeding them, contact the manufacturer.

6. Properly Install and Store Your Cable

Do not install or store the cable in a way that it will experience crushing pressure or sudden impacts. When installing cable, protect it from exterior forces by installing it in a high-quality conduit. 

The National Electrical Code states that conduit should be made with rigid polyvinyl-chloride plastic or metallic tubing, both of which can help prevent crush or impact damage. When storing cable, do not use cable ties to bind them, as these can place sharp stress on the cables. Soft hook and loop ties are a gentler binding choice that will protect your cables by reducing the amount of stress they must withstand.

7. Monitor Vertical Rise

All fiber-optic cables state whetherthey can be used for vertical applications. If they are, they provide a calculated maximum vertical rise value that indicates how far the cable can be lifted vertically before requiring a support.

For example, you might have a cable with a max vertical rise of 200 feet. This number means that you'll need to install at least one vertical support every 200 feet. Do not exceed maximum vertical rise value, otherwise, you may damage the cable.

8. Monitor Load During Pulls 

Avoid pulling long lengths in one direction. Also, if running cable vertically, start from the top and pull the cable down to avoid applying an excessive load to the cable.

9. Double-Check the Appropriate Regulations

It goes without saying, but check local and national regulations and fire codes to ensure your installation meets standards. If construction is needed, be sure you have the appropriate permit.

10. Review All Safety Procedures Before Working

All construction projects come with safety concerns, but working with fiber optics means there is a risk of exposure to chemicals and sparks. Be sure to review safety guidelines before starting a project and wear appropriate safety gear. 

11. Work With a Professional

If you are a home or business owner interested in this process, it is highly recommended to work with a professional unless you or your staff are experienced in fiber-optic cable laying. 

Multilink professionals are thoroughly trained in fiber-optic cable laying procedures and can help you make appropriate decisions about cable layout and conduit selection. They can also return for scheduled reviews of any work done to ensure it meets regional and industry standards.
