Pigtails (also known as angel wings and bunches, or Twin Tail(ツインテール/TsuinTe-ru) in Japan.) describe a
hairstyle in which the hair is parted down the middle and tied into two
bundles, one on each side of the
head. The style is popular among toddlers and young girls, and is sometimes also worn by teenagers and young women.

1 . A short length of
optical fiber that is permanently affixed to an
active device, e.g, LED or
laser diode, and is used to couple the device, using a
splice or
connector, to a longer fiber. [After
FAA] (
188 ) 2 . A short length of single-fiber
cable, usually tight-buffered, that has an
optical connector on one end and a length of exposed fiber at the other end. Note: The exposed fiber of the pigtail is then spliced to one fiber of a multifiber
trunk, i.e., arterial, cable, to enable the
multifiber cable to be "broken out" into individual single-fiber cables that may be connected to a
patch panel or an
input or
output port of an
optical receiver or transmitter. [After
FAA] 3. A short length of electrical conductor permanently affixed to a
component, used to connect the component to another conductor.
