How Does a Fiber Optic In-Line Closure Protect Optical Fibers?

Fiber Optic In-Line Closure Protect Optical Fibers

A fiber closure, also known as an in-line closure, protects optical fibers in a network. These enclosures are used to splice, joint and store fiber cable. They are typically used in CATV, telecommunications and Gigabit Ethernet networks. In addition, they help keep the cable protected from external elements like water, rodents and impact. It is important to choose the right closure for your network as it will play a crucial role in the overall network performance. In this blog post, we will discuss what a fiber optic in-line closure is and how to determine the quality of it.

A network needs to be able to reach its full potential. Whether that means connecting the network to new customers or bringing service to remote areas, a good fiber optic in-line closure is necessary. A high-quality closure will not only hold the incoming and outgoing cables, but will protect them from external elements such as water, rodents and impact. A quality closure will also be able to manage the lifetime of the optical fibers, as well as provide easy access for technicians.

While there are many different types of Fiber optic in-line closure, they all work on similar principles. They are usually made from durable plastics and have a protective mechanism that is designed to seal in the environment. They come in both horizontal and vertical designs and are commonly used in duct, underground direct buried or aerial applications.

When selecting a fiber closure, make sure that it is compatible with the type of optical fiber cable that you are using in your network. Also, look for closures with a high capacity for splice trays and the ability to accept more than one cable. Additionally, consider the accessibility of the closure, as some points in the network require reentry more often than others. Finally, if your project requires the closure to be located outside, choose a waterproof design.

A quality fiber in-line closure is able to provide a safe place for splices and joints, as well as protecting the cables from harsh weather conditions and external elements. It should be able to withstand heavy splice and joint loads as well as tensile stresses from cable shrink-back. It is also important to make sure that the closure is bonded and grounded correctly, especially if it has metallic elements.

In addition, it is important to look for a fiber in-line closure that can handle the expected growth of your network. This may mean that it has a large enough capacity for splice trays and can easily be expanded as your network grows. It should be able to accommodate pre-terminated or plain fiber for connector, mechanical or fusion splicing. Additionally, the closure should be able to house removable wavelength filters if needed. It should also be able to be mounted in the network with ease, either in an underground chamber, attached to a telco pole or in a customer’s building, while maintaining aesthetic considerations.
