Fiber optic cable installation can provide a high-performance network for your home or business, and the two main installation methods are pulling and blowing. It needs a high level of skill and attention to detail. If done incorrectly, it can lead to poor performance and expensive repairs. Therefore, fiber optic cable installation is usually performed by experienced network installers. They specialize in various fiber optic cable installation services to deliver the speed and reliability of service your business depends on. However, you can also successfully install fiber optic cable for your home or business. Bwnfiber will explore some of the fundamentals of fiber optic cable installation.

Methods of Fiber Optic Cable Installation

Fiber optic cable installation involves the laying of optical cables. Fiber optic cables are laid outdoors or indoors, depending on your requirements. There are many ways to lay the fiber cable, such as direct burial, aerial, pipeline, etc. Among, direct burial is the most convenient way to lay optical cables.

Direct Burial

The direct burial fiber optic cable is an underground fiber optic cable specially designed for direct buried installation. It is placed underground without a conduit. On the other hand, splices can be stored above ground in a pedestal or buried underground.

Aerial

Aerial fiber optic cable was erected on tower poles. You can utilize the existing overhead pole line for installation. It is one of the most cost-effective methods of deployment.

Pipeline

For other underground cables, it is generally installed in conduit pipes that are buried underground to reduce the possibility of being dug up. The fiber optic cable is carefully laid within the trench or conduit. This is achieved through using a cable-pulling machine. The fiber cables are bundled together and placed in a conduit.

Steps of Fiber Optic Cable Installation

1. Plan the route for fiber optic cable installation

The Network Installers plan the route for your fiber optic cable installation. They need to consider the length of the fiber optic cable, obstacles, and any installation tools that may be required.

2. Select the fiber optic cable type

You need to select which kind of cable best suits your requirements. There are two main types of fiber optic cable: single-mode and multimode. If the transmission is short-distance, please choose multi-mode fiber optic cable. Otherwise, use single-mode fiber optic cable. In addition, if the optical cable is not long enough, it is necessary to fuse the optical cables.

3. Collect all of the necessary tools

Besides fiber optic cables, collect all of the necessary tools, such as connectors, fiber optic strippers, fiber optic cleavers, fiber splicers, test instruments, etc. In addition, you also need to prepare pliers, tweezers, screwdrivers, etc.

4. Get the fiber optic cable

Get the fiber optic cable ready for installation. First, remove the outer jacket and inner coating to expose the fiber inside. Then you will need a fiber optic cleaver to cut the end of the cable precisely.

5. Connect the fibers to the connectors

Align the fiber optic cable with the connector and secure it.

6. Install fiber optic cables

Once everything is ready, start installing the fiber optic cable. When installing fiber optic cables, run the wires along the planned route and attach them to the appropriate termination points.

7. Test fiber optic cables

After installing the fiber optic cable, test the connection to ensure it is operational. You can use an OTDR to test the strength of the signal.

Looking for Bulk Underground Fiber Cable? 

Underground fiber optic cable is an outdoor optical cable laying underground, which can be installed in conduit pipes or buried directly into the ground. It is generally pulled within a conduit that is buried underground to reduce the possibility of being dug up. It is typically done between 36 and 48 inches underground. The minimum depth is 42 inches. The conduit is generally PVC plastic pipe. In addition, the underground cable can also buried directly into the ground. Please review our Direct Burial Fiber Optic Cable. Underground fiber optic cable provides reliable and cost-effective transmission of data. Using underground cables when connecting two distant places or cities is essential. They play a crucial role in modern communication networks.

Advantages of Underground Fiber Optic Cable

Underground fiber optic cables have many other advantages.

Reduced signal interference.

Underground fiber optic cables are less prone to signal interference. They minimize electromagnetic interference and radio frequency noise to improve signal quality and data transmission reliability. They are ideal for long-distance connections.

Cost Efficiency.

The initial installation cost of underground cables can be higher. However, they last longer and require less maintenance later on. The cost savings in this way will be much lower than the initial investment.

Beautiful and not an eyesore.

Underground cables are located out of sight and out of the way. They help create a neat and aesthetically pleasing environment in urban areas.

Withstand bad weather

The cables are buried underground. They are less likely to be damaged by adverse weather conditions. So you don’t have to worry about rain, snow, storms, etc.

Uninterrupted by Wildlife.

The underground cables are protected from wildlife damage to ensure uninterrupted connections. In contrast, aerial fiber optic cables are the main problem.

Reduced Risk of Human Interference.

Underground cables reduce the risk of human interference. In addition, underground installation eliminates the risk of accidental contact with high-voltage power lines.

Installation of Underground Fiber Optic Cable

Installing underground fiber optic cables is a critical process.

1. Planning and Design

Installing underground fiber optic cables first requires overall planning and design. It ensures that the cables are installed most efficiently. A thorough site survey is conducted to assess the terrain, soil condition, existing utilities, and any potential obstacles.

2. Trenching

Use a trenching machine to excavate a path for the conduit to house the fiber cable. The depth at which the conduit is laid depends on the soil type and size of the cables. In addition, it is also affected by local regulations.

3. Conduit Placement

Conduit provides additional protection to the cable from damage. So, conduits must be robust enough. Conduits are placed within the trench, and their fittings and connectors are securely fastened. If the cable is directly buried, no conduit is required.

4. Cable Laying

The fiber optic cable is carefully laid within the trench or conduit. This is achieved through using a cable-pulling machine. The cables are bundled together and placed in a conduit.

5. Splicing and Termination

Splicing involves joining the individual fibers within the fiber optic cable using fusion splicing or mechanical splicing techniques. The splices are then placed in protective enclosures to prevent damage.

6. Testing & Verification

Once the cables have been installed and terminated, the final step is to test the network to ensure that it is functioning correctly. It ensures that fiber optic cable enters the network correctly and functions optimally. Testing checks for faults along the cable length and verifies the network’s overall performance.

Direct burial fiber optic cable is an underground fiber optic cable specially designed for direct buried installation with steel tape or wire armor outside. Direct burial is the most convenient way to lay optical cables. It saves the cost of pipeline and overhead installation. The cable is usually made of a plastic sheath and surrounded by a protective armor. This armored fiber optic cable protects the fiber from damage caused by rodents and other animals. In addition, the direct burial cable is also designed to be moisture-resistant, which helps prevent water from seeping into it and damaging the fibers. Direct burial cable is primarily used in direct burial in the soil or underground conduits.
