Faxübertragung

FaxÜbertragung, also known as fax transmission, is a telecommunications technology used to transmit copies of documents over telephone lines. A fax machine scans a document and converts the image into an electronic signal, which is then sent through a standard phone line to another fax machine. The receiving machine decodes the signal and prints a duplicate of the original document.

This technology was widely used for sending and receiving documents quickly before the advent of email and other digital communication methods. It was particularly popular in business environments for transmitting contracts, invoices, and other important papers. The process involves dialing the recipient's fax number, establishing a connection, and then transmitting the document page by page.

The transmission speed of a fax varies depending on the technology used, typically ranging from a few seconds to a couple of minutes per page. Early fax machines were analog, while later models incorporated digital technology, offering improved resolution and speed. Despite the rise of digital alternatives, faxübertragung continues to be used in some sectors, such as healthcare and legal, due to established security protocols and the need for paper-based records. The basic principle remains the same: converting a physical document into a transmittable signal and reconstructing it at the destination.
