Optical Fibre Pigtails: Understanding the Basics

Optical Fibre Pigtails are an important component in Fibre optic cabling infrastructure. They are used to provide a reliable, high-performance connection between optical Fibres and other devices, such as switches, routers, and servers. In this article, we will explore what optical Fibre pigtails are, their differences from optical patch cords, and their various classifications based on Fibre type, connector type, interface polish type, application environment, Fibre count, and splicing.

What are Optical Fibre Pigtails?

Optical Fibre pigtails are short, pre-terminated Fibres that are spliced onto the end of an optical Fibre cable. They are typically 0.9mm or 2.0mm in diameter and are available in various lengths, Fibre types, connector types, and polishing types. Pigtails are used to provide a connection between a Fibre optic cable and other devices, such as patch panels, switches, or routers. They are available in single-mode and multimode Fibres, with different connector types such as LC, SC, ST, FC, and MTP.

Optical Patch Cords vs. Pigtails

Optical patch cords are cables that connect two devices with optical Fibre connectors. They are used for temporary connections and are not spliced onto the end of an optical Fibre cable. In contrast, optical Fibre pigtails are spliced onto the end of an optical Fibre cable, providing a permanent connection. The pigtails are then connected to other devices with patch cords.

Fibre Type

Optical Fibre pigtails are available in single-mode and multimode Fibres. Single-mode Fibres have a small core diameter (typically 9 microns) and are designed for long-distance transmissions. Multimode Fibres have a larger core diameter (typically 50 or 62.5 microns) and are used for shorter distances.

Connector Type

Optical Fibre pigtails are available in different connector types, such as LC, SC, ST, FC, and MTP. LC connectors are small-form-factor connectors, while SC connectors are more common and have a square shape. ST connectors are circular connectors that are commonly used in industrial applications, while FC connectors are threaded connectors that are commonly used in telecom applications. MTP connectors are multi-Fibre connectors that can support up to 12 Fibres.

Interface Polish Type

Optical Fibre pigtails are available in different polishing types, such as PC (Physical Contact), UPC (Ultra Physical Contact), and APC (Angled Physical Contact). PC polishing is the most common type and provides a low insertion loss and high return loss. UPC polishing provides an even lower insertion loss and higher return loss. APC polishing provides the highest return loss, making it suitable for high-speed, long-distance transmissions.

Application Environment

Optical Fibre pigtails are available in different jacket materials to suit different application environments. For example, indoor applications typically use PVC or LSZH (Low Smoke Zero Halogen) jackets, while outdoor applications typically use polyethylene or polyurethane jackets. LSZH jackets are preferred for indoor applications because they release less toxic smoke in the event of a fire.

Fibre Count

Optical Fibre pigtails are available in different Fibre counts, from single-Fibre to 12-Fibre pigtails. The most common Fibre count is duplex (two Fibres), which is used for transmitting and receiving signals simultaneously.

Fibre Pigtail Splicing

Optical Fibre pigtails are typically spliced onto the end of an optical Fibre cable using fusion splicing or mechanical splicing. Fusion splicing provides a low insertion loss and high tensile strength, making it suitable for high-performance applications. Mechanical splicing is a simpler and less expensive method, but it provides a higher insertion loss and lower

Conclusion:

In conclusion, optical Fibre pigtails are an essential component in Fibre optic cabling infrastructure, providing a reliable and high-performance connection between optical Fibres and other devices. They are available in different Fibre types, connector types, interface polish types, application environments, and Fibre counts. Splicing is a critical step in installing optical Fibre pigtails, and the two common methods are fusion splicing and mechanical splicing.
