How to connect fiber optic cables: 3 different methods to easily achieve!

Regarding how to connect fiber optic cables, optical fiber is an excellent solution for various network applications. This is because it can transmit large amounts of data over long distances and at impressive speeds. However, if you want to fully harness the potential of fiber optics, it's crucial to connect everything correctly. Generally, there are three methods to connect fiber optic cables. Our guide will cover them so that you can choose the most suitable option.

The purpose of these devices is to connect the cable to another component in the network setup. Additionally, you can use connectors to create a joint between two fiber optic cables.

You'll find many types of connectors on the market. However, they differ in terms of back reflection and optical loss. Therefore, you should choose the best option for your application. Commonly, ST connectors are found in campuses and office buildings. Additionally, you'll find them in other facilities using multimode networks. On the other hand, FC and SC connectors are suitable for single-mode systems.

You can use splicing to join two cables together. Additionally, this technique is a great way to connect fiber optics. This is because it minimizes back reflection and optical loss. Therefore, it's a suitable choice for connecting two types of cables or if a single cable is pulled too long.

Check out the main types of fiber optic splices below!

Mechanical Splicing

This technique involves using an alignment sleeve. Therefore, your goal is to place the sleeve between the ends of two fiber optic cables. This device secures both ends in place while ensuring that light passes through between the cables. Experts estimate that with this method, you can expect a loss of around 0.3dB.

The main advantage of this method is its cost-effectiveness. On the other hand, while the initial investment is lower, the cost per mechanical splice will be higher than fusion splicing. This makes mechanical splicing less suitable for large-scale projects. Additionally, you wouldn't want them in applications where you aim to achieve as little optical loss as possible.

Fusion Splicing

Fusion technology involves two steps.

This method is excellent for maintaining a stable connection between two fiber optic cables. Therefore, the estimated loss is only 0.1dB. This ensures better performance than mechanical splicing. However, the initial investment for fusion splicing is higher. Thus, the setup might cost you three times as much. On the other hand, the cost per splice can be cheaper by 20 times. Therefore, fusion splicing is a wise choice for large-scale and long-term projects.

Pre-terminated fiber optic cables mean that the manufacturer has processed them before sending them to the destination. Depending on your preference, there are two termination methods to choose from!

Pre-connection and Field Installation/Splicing

The first option is the so-called 50/50 method. Thus, you get a cable with one end pre-terminated. On the other hand, there is a connector on the other end that needs to be terminated in the field.

This method ensures that you always have the optimal cable length. So, you don't have to worry about having overly long cables that strain the eyes. However, the downside is that you need a qualified technician to handle the on-site termination. Thus, installation time will be longer, and labor costs will increase.

Pre-terminated or Factory-terminated

If you want to simplify things, you can opt for factory-terminated fiber assemblies. This method means that the manufacturer has addressed the termination issue before shipping. Fortunately, most brands do this in state-of-the-art facilities to ensure no shards or other issues. Therefore, the staff ensures that the cable terminations are smooth to ensure optimal performance. Additionally, they typically test the cables before shipping them to the destination.

The main advantage of factory termination is that no work needs to be done on-site. Thus, this speeds up the entire installation process, increasing efficiency. Furthermore, it reduces labor costs, allowing you to offer better prices to customers.

On the other hand, the downside of factory-terminated cables is their length. Therefore, you need to carefully select the required distance. Otherwise, you may end up with overly long cables, which detracts from aesthetics. Additionally, if the cable ends up being too short, it may not be usable for the project.
