How to Select Microcable Size Based on Micro Tube?

Microfibre cables are an essential part of modern telecommunications and data networking systems, capable of transmitting large amounts of information over long distances. These cables are typically housed in microtubes, which provide mechanical protection, environmental resistance, and ease of installation. Selecting the correct size micro fiber optic cable is critical to ensuring optimal performance and avoiding potential problems such as signal loss, attenuation, or damage to the cable itself.

In this article, we will explore the key factors to consider when selecting the appropriate microcable size based on the microtubes that will be housed within it.

Microtube Inner Diameter

The first and most critical consideration is the inner diameter of the microtubules. This parameter determines the maximum outer diameter of the micro-cable that can fit inside the tube. Therefore, to accurately measure the inner diameter of the microtube, it is very important to select a microcable whose outer diameter is smaller than or equal to the inner diameter of the microtube.

Number of Microcables

The number of micro-cables that will be housed within the micro-tube is another key factor to consider. This parameter will determine the amount of space available for each micro-cable, which in turn affects its outer diameter. If several micro-fiber cables are installed in the same micro-tube, it is necessary to ensure that there is enough space for each fiber-optic cable to avoid any potential signal interference or damage due to friction or pressure.

Fiber Type

The type of micro-fiber you choose also affects its outer diameter. Different types of micro cables have different diameters depending on their design and construction. For example, some microfiber cables may have thicker insulation or shielding, which increases their outer diameter. Therefore, it is critical to select a micro fiber optic cable that meets the specific requirements of your application while considering the constraints imposed by micro tubes.

Bending Radius

The bend radius of the microtube is another important parameter to consider when selecting the appropriate microcable size. The bend radius is the smallest radius the tube can bend without damaging the micro-fiber cable or affecting its performance. If the micro-fiber cable is too thick or too rigid, it may not be able to bend to the desired radius, resulting in loss or damage to the signal. Therefore, it is crucial to select microcables that are flexible enough to meet the bending radius requirements of microtubules.

Environmental Conditions

Finally, it is important to consider the environmental conditions in which micropipes and microcables are deployed. Factors such as temperature, humidity, and exposure to chemicals or UV radiation can affect the performance and longevity of microfiber cables. Therefore, it is imperative to select a microfiber cable that can withstand the specific environmental conditions of your application while meeting the constraints of the microtube.

In summary, selecting the appropriate microcable size based on the microtube requires careful consideration of several key factors, including the inner diameter of the tube, the number of microcables, cable type, bend radius, and environmental conditions. By taking these factors into consideration, you can ensure optimal performance and reliability of your microfiber cable system.
