Finding the relationship between pigtail fiber
They are the bridge between fiber optic cables in the field and the equipment or patch panels that manage them. By combining factory-installed connectors with spliced bare fiber, pigtails ensure that network installers can create fast, reliable, and cost-effective terminations. These small, easy-to-use components are popular in data centers, business networks, and service provider systems. A pigtail fiber indicates a short length of optical fiber cable that has a pigtail connector (for example, SC, FC, ST, LC, etc. ) fitted on one end and the other end undressed (for connection through fusion or splicing) to the main fiber optic cable.
