What is a fiber pigtail?

A fiber pigtail is indeed a fiber-optic cable with pre-connectorized ends. This type of fiber is used primarily in telecommunication applications to facilitate connections between different components in a fiber-optic system. The pre-connectorized design simplifies installation, as it allows for quicker and easier connections compared to splicing individual fibers.

By having connectors already attached, technicians can expedite the setup process, ensuring that network deployment or repairs are efficient. This is particularly beneficial in environments where minimizing downtime is essential.

In contrast, the other options refer to different concepts. A connector for short fiber lengths does not accurately describe a pigtail, as pigtails are typically longer and designed to connect to other cables or devices. A type of fiber amplifier does not relate to the physical characteristics of a fiber pigtail, which does not amplify signals. An extension of a fiber-optic cable could imply a particular function, but it does not capture the essence of what a pigtail is; pigtails are not extensions but rather integral connecting components.
