Assembly of optical fiber pigtail with collimated lens assembly are the main elements of optical connections used in modern fiber-optic transmission devices. The efficiency and stability signal transmission depend on the adjustment accuracy of its parts. It is transmitting or receiving elements of the optical signal, providing minimal optical losses, which is important for reliable signal transmission over long distances. The article investigates the method of assembling and adjusting individual components of assembly optical fiber pigtail with collimated lens used in fiber-optic communication. The characteristics of the assembly fiber pigtail with collimated lens components that affect the optical loss of the signal during its transmission through the optical channel are analyzed. The required accuracy of the mutual connection of the assembly fiber pigtail with collimated lens components is calculated. A description of the developed stand and optical-mechanical prefabricated elements is given, which were developed to achieve acceptable accuracy of the mutual component of the assembly fiber pigtail with collimated lens components by the limiting method. Experimental testing of the research method is carried out. The results are obtained in the form of an assembled and adjusted optical optical fiber pigtail with collimated lens, which has a number of advantages over analogues. The optical channel connection is shown, which constitutes from two fiber pigtails assemblies, recorded by the method. The main characteristics of the shown optical channel are measured. The results of the study allow to create an assembly optical fiber pigtails with collimated and to apply mechanical elements with high processing accuracy in the pole structures.
