Especially when we consider optical fibers, most of the mechanical failures are due to the stress applied. If there is a presence of moisture, then the cables should also face some fatigue phenomenon. Hence usage of fiber optic cable that is waterproof is very important.

The manufacturers of these cables should be aware that the cables should be able to withstand outdoor use. Hence, they should keep in mind that cable should be manufactured in a way so that it is possible to protect it from the moisture. To solve this problem, the majority of manufacturers rely on a waterproof technique. The material that is preferred in this area for manufacturing waterproof fiber optic cables is UV-cured acrylic material. Along with bringing benefits in terms of speed, this material is resistant to water. For more information, visit https://www.bma-tech.com/product_detail/index/8686/245.
Varieties of designs in fiber optics cables
There are mainly two different design techniques that are utilized for providing protection against moisture and water while manufacturing fiber optics.
One method is they will make use of loose tubes that are gel-filled cables. This helps in preventing the water to reach the coated fibers. In this approach, they make the cable waterproof through filling all the empty space present inside the cable using a gel. This helps in preventing the water to go inside and reach coated fibers.
These filled cables will later undergo a hosing test to make sure they are waterproof. Through this test they ensure that water is not going inside. But there is a drawback to this method. Understand that gels can always flow, move, and even they settle. This brings uncertainty.
Another method is tight-buffered and tight bound outdoor and indoor cables. This utilizes a different approach. It deals with moisture by going against it. That is, in this approach the cable is made water-resistant rather than making it waterproof. Hence the cables manufactured using these methods are water tolerant.
Both methods result in cables that are waterproof. But through the second method you can receive cables that are durable and reliable more than that they are definitely water tolerant. There is no uncertainty in the second method since the resulted cable will be water tolerant.
It is very important to concentrate on fiber surface where actually the fiber comes in contact with the moisture or water. So along with all other things like issues of inherent waterproofing and plastic material’s porosity, making the changes to the surface is very important.
Whichever method may be used for manufacturing waterproof cables, the end result should be waterproof cable that can resist both moisture and water. The cable manufactured should be suitable for both indoor and outdoor uses.
