Fiber Optic Pigtail Guide
A pigtail is a short fiber with a connector on one end and bare fiber on the other. It is the bridge between a spliced cable and a connectorized termination. This guide explains how pigtails are used. It is a guide only; no pigtail product is listed on this site.
What a pigtail is for
Cables arriving at a box or frame need connectors, but fitting a connector directly to a cable fiber on site is slow and error-prone. A pigtail solves this: its bare end is spliced to the cable fiber, and its connector end plugs into the panel, box or frame. The splice lives protected inside the enclosure, and the connector is ready to use.
Pigtails are consumables of network building. Every termination point in a new installation typically needs one per fiber, so pigtail quantities follow directly from the termination plan.
Pigtails in boxes, frames and closures
In a terminal box, pigtails connect drop or distribution fibers to the box's connector field. In a distribution frame, they connect backbone fibers to the patching field. In a closure, a pigtail can present a spliced fiber for testing without disturbing the joint.
Because pigtails are small and numerous, labeling matters disproportionately. An unlabeled pigtail is a guess at fault time. Label pigtails at both the splice record and the connector position.
What to confirm about pigtails
- Connector family and polish type, matching the panel or box.
- Fiber type, matching the cable and the link.
- How pigtails are labeled and recorded at each termination.
- Spare pigtails for rework, kept with the same labeling scheme.
- Confirm MOQ and lead time for your specification in your inquiry before ordering.
