In fiber optic cable installation, the success of the network depends on how the cable is connected to the system. If the operation is correct, the optical signal can easily pass through the connected cable, and the risk of power loss is very low. Fiber pigtails are the preferred way to connect fibers and are used in 99% of single-mode applications. (source)

An optical fiber pigtail is an optical fiber cable with a factory-installed connector at one end. Therefore, one side can be melted with the fiber optic cable, and the side connecting the connector can be connected to various devices. Mechanical splicing or fusion splicing is used to terminate fiber optic cables with pigtails. For best performance, use high-quality pigtail cables and the correct splicing method. Pigtails often appear in fiber management equipment, such as distribution boxes, fiber terminal boxes, and ODFs. Since the connector end is connected at the factory, the quality of the pigtail tends to be better compared to the field terminated cable.

One end of the fiber pigtail is left blank, and the other end is equipped with a fiber connector. On the other hand, there is an optical fiber connector at each end of the optical fiber jumper. Jumper cables usually also have a sheath, and in contrast, fiber-optic pigtail cables usually do not have a sheath because they tend to be spliced ​​and protected in a splice tray. The jumper can be cut into two sections to make two pigtails. For some installers who want to avoid the problem of field test pigtails, this is a preferred method because it is easier to test the performance of the fiber jumper.

There are many types of fiber pigtails available. They are grouped by connector type, fiber type, number of fibers, or application environment.

There are different types of fiber optic pigtail connectors, where the cable is terminated at the end. The most common options are LC, SC, ST, FC, MT-RJ and E2000 fiber pigtails. They have different structures and appearances, and have their own advantages in various systems and applications.

Fiber pigtails can be divided into two different types: single-mode and multi-mode. Single-mode fiber is usually yellow, while multi-mode fiber is usually orange. The multimode fiber pigtail is terminated with a multimode fiber connector at one end and uses 62.5/125 micron or 50/125 micron bulk multimode cables.

The fiber pigtail has a variety of fiber counts, which can provide 1, 2, 4, 6, 8, 12, 24, and 48 fiber counts. The simplex fiber pigtail has one fiber and one connector, while the duplex fiber pigtail provides two fibers and two connectors. In order to mark the polarity, each fiber is marked with A or B, or use a different connector to guide the color.

Some fiber pigtails are specially designed and installed to withstand extreme or severe weather or environments. These fiber optic pigtail options are usually waterproof or armored.

Optical fiber pigtails are used for fusion splicing with optical fibers to connect them to various types of equipment or patch panels. They provide reliable and feasible solutions for effective fiber optic cable termination. There are many types and they are suitable for almost any type of application or purpose. Therefore, they are the key to saving operating costs and labor time for installers.
