Butterfly -shaped optical fiber optical cable side connection method

Updated on Mon Aug 18 2025

Butterfly-shaped optical fiber cables are a popular type of fiber optic cable that is commonly used for data transmission in telecommunication networks. They are called butterfly-shaped due to their unique design, which features a flat shape with two parallel fiber ribbons running down the center of the cable. There are several ways to connect butterfly-shaped optical fiber cables, and in this article, we will discuss four of the most common methods.


Fusion Splicing

Fusion splicing is a popular method of connecting butterfly-shaped optical fiber cables. It involves welding two fiber cables together using heat. The two fiber cables are stripped of their protective coatings, and their bare ends are aligned and then fused together using a fusion splicing machine. The machine applies a high voltage arc to the two bare fiber ends, melting them together to form a permanent bond.


One advantage of fusion splicing is that it produces a low-loss connection, which means that there is little to no signal loss when data is transmitted through the cable. Additionally, fusion splicing is a relatively fast and easy process, making it a popular choice for technicians working in the field.


Mechanical Splicing

Mechanical splicing is another method of connecting butterfly-shaped optical fiber cables. Unlike fusion splicing, mechanical splicing does not require the use of heat. Instead, a mechanical splice is used to join the two fiber cables together.


A mechanical splice is essentially a small connector that holds the two fiber cables in place and aligns their ends. The connector is tightened using a special tool, which compresses the fibers together, creating a strong and secure connection. Although mechanical splicing is not as fast as fusion splicing, it is a popular choice for technicians who need to make temporary connections.

Direct Termination

Direct termination is a method of connecting butterfly-shaped optical fiber cables that involves attaching a connector directly to the end of the cable. This method is often used when the cable needs to be connected to a patch panel or other equipment. The connector is attached using a special tool, which strips the protective coating from the end of the cable and attaches the connector.


Direct termination is a popular choice because it is fast and easy to perform, and it produces a low-loss connection. However, it is not as reliable as fusion splicing or mechanical splicing, and it can be difficult to re-terminate the cable if the connector becomes damaged.


Pigtail Splicing

Pigtail splicing is a method of connecting butterfly-shaped optical fiber cables that involves splicing a short length of fiber optic cable to the end of the butterfly-shaped cable. The pigtail cable is then terminated with a connector, which can be connected to a patch panel or other equipment.


Pigtail splicing is a popular choice because it is fast and easy to perform, and it produces a low-loss connection. Additionally, pigtail splicing is more reliable than direct termination because the pigtail can be easily replaced if it becomes damaged.


In conclusion, there are several ways to connect butterfly-shaped optical fiber cables, each with its own advantages and disadvantages. Fusion splicing is a popular choice for permanent connections because it produces a low-loss connection and is relatively easy to perform. Mechanical splicing is a good choice for temporary connections, while direct termination and pigtail splicing are popular choices for connecting to patch panels and other equipment. When choosing a connection method, it is important to consider the requirements of the specific application to ensure that the connection is reliable and low-loss.
