Why Choose Pre-terminated Fiber Pigtail?

In fiber optic cable installation, how to connect cables to the system is the key to the success of the network. If done correctly, the optical signal can pass through the link with low attenuation and little return loss. Fiber pigtail provides an optimal way to connect optical fibers, which is used in 99% single mode applications.

What Is Pre-terminated Fiber Pigtail

The fiber pigtail of the pre-terminated method is a dedicated hardware connection for cable termination, which passes through the same procedure as the field-terminated fiber pigtail. But these steps are taken at the manufacturer’s facility or cable assembly. Pre-terminated fiber pigtails provides more convenient, easier installation and higher performance than field-terminated fiber pigtails. On the fiber pigtail, one end is bare fiber, and the other end has a pre-installed connector. Fiber pigtail is usually spliced on the strands of multi-fiber trunk cables. Simply speaking, optical fiber pigtail equals optical fiber connector plus fiber optic cable. There are many kinds of fiber pigtail. For example, according to the type of connectors terminated on optical fiber cable, optical fiber pigtail can be classified into FC, ST, SC pigtail.

Advantages of Using Pre-terminated Fiber Pigtail

So, what are the advantages of using pre-terminated fiber pigtail? Why do we use the pre-terminated fiber pigtail?

Superior Performance

One of the main advantages of pre-terminated fiber pigtail is that controlled, pre-terminated factory processes results in superior performance. The uniform and high quality connector end face geometry leads to lower insertion loss and better end-to-end attenuation.

Time & Cost Saving

Because the tails are ready to be installed immediately, there is no connector waste, no tedious tool kits or no need of special testers. Customers reported that the average cost reduction of the pre-terminated fiber pigtail was 20% to 30%, mainly thanks to time and labour savings in the field termination practices.

Environmental Friendliness

In addition to the advantages of having no need to test network performance, reducing downtime, rapid deployment and easy maintenance, the pre-terminated fiber pigtail is also environmentally friendly, eliminating waste and consumables associated with field termination. With the reduction of material cost and better flexibility, pre-terminated fiber pigtail is the better choice of most modern users.


Safety is always placed in the most important position in data centers. The pre-terminated fiber pigtail does provide many security benefits. Using the pre-terminated fiber pigtail, the installation needs less manpower, so the required expertise is less, and users can even use their own team to do the work.


In fact, most people are willing to choose pre-terminated fiber pigtail because it can provide easier installation ways to speed up data center deployment, reduce costs and errors, and provide great flexibility. That’s why we use it. But if you want to find out which terminated solution is most suitable for your installation, you need to consider all the factors, including consumables, tools, labor, proper training, and rework if needed. Besides, you need to remember that you can terminate and install the pigtail at the job site. If you need more details, please visit FS.COM.
