Unveiling Loose Tube Microcables:

Loose tube microcables are designed to protect optical fibers when deployed in a number of different scenarios. The cable design comprises a central strength member surrounded by tubes of loosely arranged optical fibers, offering excellent resistance against moisture, temperature variations, and physical stress. Let’s understand the design of a loose tube microcable in detail:

Structure of the Loose Tube Microcables:

Loose tube microcables have a simple yet effective structure. Groups of individually coated fibers are organized in a series of plastic tubes within the cable. This plastic tube sub-unit is designed to be robust, protecting the fibers from damage under various mechanical loading. To keep moisture out, the tube is filled with a special gel that blocks water from entering.
The strength of loose tube microcables lies in their ability to accommodate different use cases. primarily deployed within microducts. Their sturdy design allows them to withstand a variety of different installation scenarios and conditions. Experts strongly recommend that the right installation method for loose tube microcables is to blow them into the microducts, although short runs of microcable installed under low tension may also be acceptable.

FAQs

Standard loose tube cables come in different diameters, with a 144-fiber cable typically possessing a diameter of 15-16mm. In contrast, microcables can achieve a diameter of approximately 6mm, making it less than half the size and about one-third lighter. This compact size enables the deployment of higher fiber counts, with some microduct installations accommodating over 3,000 fibers.

The main difference between tight buffered and loose tube cables lies in their construction and intended environments.

Feature Loose Tube Cable Tight Buffered Cable
Fiber Count High fiber count Lower fiber count
Structure Multiple fibers held loosely within a subunit 1F held in a single tight buffer tube
Protection Excellent protection against pulling tension and moisture Less protection against pulling tension and moisture
Environment Ideal for outdoor and harsh environments Ideal for indoor and controlled environments
Installation Typically buried directly, installed overhead, or in duct depending on design Typically used in indoor settings or shorter distances
Handling More careful handling is required due to the thin buffer coating on fibers Easier to handle due to thicker buffer coating on fibers
Applications Long-haul telecommunications, outdoor installations LANs, data centers, indoor applications

There are various types of loose tube cables that can be classified by fiber type, such as single mode and multimode. Additionally, they are often categorized by their structural designs:

Central Tube Cables: This design hold fibers inside of a tube that occupies the center of the cable cross section. This construction is cost-effective for a variety of different fiber counts. They require fewer breakout kits during installation, saving time and space.

Loose Tube Cables These cables have multiple sub-unit tubes around a central strength element. They are typically used for outdoor installations and are resistant to environmental factors. Indoor-outdoor variants are also available.

Dry Loose Tube Cables These gel-free cables utilize advanced water-blocking technology and reduced-diameter buffer tubes. They offer full water protection without gel filling, making them an alternative to traditional gel-filled loose tube cables.

Yes, loose tube microcables are suitable for outdoor installations. The design of loose tube microcables provides excellent protection for the fibers against environmental factors such as moisture, temperature variations, and physical stress. These microcables are highly resilient and ideal for outdoor applications where exposure to harsh conditions is expected, such as in aerial, buried, or duct installations.
