Network Cable Inc. offers end-to-end fiber optic installation services, which include Fiber To The Premises (FTTP), FOSC Vault Conduits, Splitter install, and GPON Planning and Design. Implementing best practices in fiber optic cabling installation ensures the optimal performance of your connections.

Types of Underground Fiber Optic Installation Methods

There are various methods to install underground fiber optic cables, each with its own advantages and considerations. Here are some of the most common techniques:

Trench Drop Conduit

This method involves digging a trench to place a conduit, through which the fiber optic cables are blown in. This is one of the most straightforward techniques and is widely used due to its simplicity and ease of maintenance.

Horizontal Drilling Drop Conduit

Using horizontal drilling, you can create a channel beneath the surface to lay the conduit. This method is ideal for situations where direct surface disruption is not an option. Special machinery is required, and it provides added flexibility in laying the cables.

Trench Drop Fiber (Chicken Scratch Drop)

This method involves trenches alongside train tracks. This technique is very common and has the advantage of utilizing pre-existing infrastructure. Special machines are designed for this particular task.

Trench Drop Conduit without Fiber

This option involves creating a trench but not burying the fiber right away. This is not recommended for standard installation, but it can be useful in certain specific scenarios.

Utilizing Existing Pipelines or Tunnels

Another effective method is to find an old pipeline or existing tunnel, such as a subway system, and hang the fiber cables from the existing infrastructure. This method is cost-effective and leverages pre-existing infrastructure.

Steps to Install Underground Fiber Optic Cables

When installing underground fiber optic cables, it's crucial to follow best practices to ensure the cables perform optimally and are protected from damage. Here’s a step-by-step guide:

Prepare the Cables and Materials

Before beginning the installation, ensure you have the appropriate cables, conduit, and other necessary materials. Fiber optic cables are armored and designed for outdoor use, either buried or aerial. Conduit is recommended for easier pulling and replacement.

Choose the Appropriate Method

Select the most suitable method based on the specific requirements and available infrastructure. If you are using a trench method, ensure it is properly dug and lined with the appropriate materials.

Install the Cables

When installing the cables, do not use the strands for pulling; instead, use the yellow Kevlar thread or directly attach to the sheath. Pulling the strands can cause fractures and damage throughout the cable.

Termination Process

The final step is to correctly terminate the fibers. This process is dependent on the type of end being used. Ensure that the termination is secure and properly sealed to prevent moisture intrusion.

Protect Against Moisture

OSP (Outside Plant) cables are armored and designed for outdoor use. They contain a gel or powder that helps keep moisture out and prevents it from spreading down the cable. Protecting the cables from moisture is essential for maintaining performance and longevity.

By following these best practices and steps, you can ensure the successful installation of underground fiber optic cables. Network Cable Inc. is a trusted provider of fiber optic installation services, and their expertise can significantly benefit your communication infrastructure.
