A fiber optic pigtail, also known as a fiber optic cable tail, is a type of fiber optic cable assembly that provides connection between fiber optic components or fiber optic cables. It is typically used to connect fiber optic transceivers, fiber optic switches, fiber optic splitters, fiber optic patch panels, and other fiber optic devices to fiber optic cables.
The fiber optic pigtail is a short length of optical fiber that is terminated with a connector at one end and spliced to the end of a fiber optic cable at the other end. The connector typically has a male or female connection interface that can be inserted into or connected to the corresponding female or male connection interface of another fiber optic component or cable. The fiber optic pigtail allows for easy insertion and replacement of the fiber optic component without having to terminate or splice the fiber optic cable itself.
The fiber optic pigtail performs several important functions
- It provides a means of connection between different fiber optic components or cables, allowing for easy interconnection and reconfiguration of the fiber optic network.
- It ensures reliable and stable transmission of optical signals between the fiber optic component and the fiber optic cable, minimizing signal loss and noise.
- It protects the optical fiber from damage during installation and operation, reducing the risk of signal interruption or network failure.
Types of fiber optic pigtails that commonly used
- FC-SC, which is generally a round-to-square pigtail. FC connects to the ODF box, and SC connects to the optical port of the device. This type of fiber optic connector was widely used in early SBS and Optix equipment.
- FC-FC, commonly known as round-to-round pigtail. Generally used as fiber jumpers between ODF racks.
- SC-SC, commonly known as square-to-square pigtail, is generally used to connect optical boards between devices.
- SC-LC, LC interface is commonly known as small square head pigtail, which is a snap-on connector. Currently, Huawei OSN series equipment, ZTE S series equipment, including early Lucent wavelength division equipment, all use this kind of optical fiber connector.
- LC-LC is generally used in the internal fiber connection between wavelength division equipment. This application is relatively rare.
When installing or replacing a fiber optic component, it is important to ensure that the correct type and configuration of fiber optic pigtail is used to match the fiber optic connector type and interface standard of both the component and the cable. This ensures a reliable and stable connection that will not compromise the transmission performance of the fiber optic network. In addition, it is crucial to follow proper installation procedures when installing the fiber optic pigtail to avoid introducing bending or stress on the optical fiber that could result in signal loss or network failure.
Conclusie
The fiber optic pigtail is an essential component for fiber optic communication networks, providing a convenient means of connection between fiber optic components or cables while ensuring reliable and stable transmission of optical signals.
