What is pigtail and why you can't do without it

An optical pigtail is a length of fiber optic cable that has a connector at one end pre-installed at the factory and the other end remains unconnected. This allows one side of the pigtail to be connected to an optical device and the other – to be connected to an optical cable. Optical pigtails are used to complete optical cables using mechanical connections or welding.

High-quality pigtails, following the splicing technique, ensure optimal performance in the completion of optical cables. The term "pigtail" comes from the English word "pigtail" (meaning "pigtail"). This reflects both the appearance of this switching cable and the way it is connected. Such articles are indispensable when it is necessary to complete the end point of a linear optical cable.

The classification of pigtails is related to the characteristics of the cable and connectors (on one of the two ends). The optical fiber in the pigtail can be:

In diameter, the first are several times smaller than the second. For example, a single-mode cable having a 9/125 marking is characterized by the presence of a 125 µm diameter shell and a 9 µm diameter fiber, while a multimode pigtail may have a 50/125, 62.5/125 marking, etc.

A single-mode pigtail guarantees signal transmission without variances between modes, since it is one in this case. The principle of operation of multimode pigtails of these dispersions is related. According to the standard, the outer shell of pigtails is colored in different colors, depending on which the type of fibers is determined, – single-mode are yellow, and multimode – are orange. But you should remember that there may be more color options in general, which is related to the diameter and classes of the optical fiber. But absolutely all pigtails have the same shell diameter – 125 μm.

Optical pigtails are widely used in various fields where fiber-optic communication is used:

Thus, you can buy pigtails on https://a-comms.com.ua/sma-pihteily/ for various purposes.

Important characteristics of pitgales include the number of connection cycles for which the connector is designed. Usually, this indicator is an average of 1000 connections. Also, for each type of wire, there is a temperature regime in which it can work. The most mobile ones work at temperatures from -40 to +80. In order for all the variety of cords to be easily distinguished, manufacturers use special marking.

The price of optical pigtail depends on all these characteristics, as well as on the manufacturer. You should not stop your choice on very cheap options, as there is a risk of buying a low-grade cable that will not pass the signal in the right volume and in the right quality. Because of this, it is worth choosing not according to price, but according to the quality of products. Savings in case are definitely inappropriate.

These mounting cords are distinguished by the type of connector installed at one end. Today, pigtails with connectors such as sc, st, fc and others are widely used. However, for the installation of modern optical fiber telecommunication systems designed for the transmission of various information, sc type pigtail is most often used. Next, a special coupling can be used to connect to another optical cable.
