The fiber optic patch cord and fiber optic pigtail are crucial in the fiber optic network. They have many similarities and also differences in some aspects. Understanding the similarity and differences will help you to make the best choice for your project. This article will explain the similarity and differences between fiber optic patch cords and fiber optic pigtails.　

Similarity of Fiber Optic Patch Cord and Fiber Optic Pigtail
Fiber optic patch cords and fiber optic pigtails have a similar structure. They are available in single-mode (SM) and multi-mode (MM) fibers, simplex, and duplex. In addition, they can terminate with many types of fiber optic connectors, including SC, LC, FC, ST, MTRJ, MTP/MPO, MU, E2000, etc.

Fiber Optic Patch Cord Vs. Fiber Optic Pigtail
1. The fiber optic pigtail has only one end with a fiber connector installed, and the other end is left open. While both ends of a fiber optic patch cord have connectors installed.

2. The fiber optic patch cord could have two different connectors installed on each end, such as from SC to ST. While fiber optic pigtails have only one connector.

3. The fiber optic patch cord is usually jacketed, while the fiber optic pigtail is usually unjacketed. In addition, the fiber optic pigtail is spliced and protected in a fiber splice tray.

4. Fiber optic patch cords come in simplex (1 fiber), duplex (2 fibers), and 12 fibers count (MPO connector patch cables).

5. Fiber optic patch cords can be cut into two pieces to make two pigtails. This is because testing a pigtail in the field is not easy. The unterminated end is difficult to check until the pigtail is spliced to the equipment. Some installers avoid this issue by buying an unjacketed fiber optic patch cord, testing its performance, then cutting it into halves as two pigtails.

Conclusion
A fiber optic patch cord is a fixed-length piece of cable with fiber connectors on each end, while a fiber optic pigtail has fiber connectors on only one end of the cable. Fiber optic patch cords can be cut into shorter lengths to make two pigtails. Sun Telecom provides total and customized solutions of fiber optic products to the global market.
