  • September 08. 2016
Optical pigtail and patch cord are the most conventional and used network connecting products. They have many common features, but still having some differences in many ways. Understanding the similarities and differences between them will help you decide the best choice for your project application. Here we will talk about their similarities and differences through the structures.

Structure comparison of optical pigtail and patch cord

※ Definition
optical pigtail is also called pig tail, means that only one side has the connector, while the other side is a bare fiber of optical fiber core, it must need to be welded when connecting with other optical fiber core.

Optical patch cord is a short fiber cable with connectors on both sides. The connector types at both ends of the fiber cable can be either the same or different. Following picture will show a optical pigtail and patch cord.



※Similarities:
They both have single mode and multimode fiber types, and their connector types can be made into simplex and duplex. In addition, Not only optical pigtail, but also patch cord can be connected with a variety of optical connectors, such as FC, SC, ST, LC, MTRJ, MPO, MU, E2000 etc.



※ Differences:
The main difference of optical pigtail and patch cord in the structure is that optical patch cord is a fixed length of fiber cable with connectors at both sides, while optical pigtail is the fiber cable with connector at one side. Besides, a complete optical patch cord can be cut into two shorter length optical pigtail.



ETU-Link can provide a series of high quality optical pigtails and patch cord with LC, SC, ST, FC connectors. We also offer a variety of single mode and multimode optical pigtail and patch cord. These patch cords and pigtails support low insertion loss and good repeatability, and can be customized length. We verify the stability of patch cords over thousand times of plug, as all of our modules test must be achieved through the patch cord plug. This is enough to prove the life and stability of our products.
