What does the term "pigtail" refer to in fiber optics?

In fiber optics, the term "pigtail" specifically refers to a short length of optical fiber that has a connector on one end, allowing it to connect to other fiber optic cables or devices. This configuration is commonly used in applications such as splicing, where the pigtail can be attached to a length of fiber already installed in a system. The other end of the pigtail is typically left bare or spliced to another fiber, making it versatile for various networking needs.

The use of pigtails helps simplify installation and maintenance, reducing the need to connect and reconnect multiple fibers within a network. Their design is crucial for ensuring efficient connectivity while maintaining the integrity of the fiber optic system.
