During the 20th century, all public telephone networks were built with this technology and even today the so-called ‘last mile’, i.e. the cable that actually enters homes, is a telephone pair. The only exception is FTTH – Fiber To The Home, which allows optical fiber to finally enter homes directly.. The only exception is FTTHFTTH “Fiber to the Home” is the technology that connects POPs, located in exchanges, to end users’ property units with fiber optics. – Fiber To The Home, which allows optical fiberOptical fiber A cable made of glass fiber through which a light signal is transmitted over long distances for broadband network access. Compared to copper cables, optical fiber can transmit signals much faster, up to 40 Gigabits per second. It is therefore ideal for quickly transferring large amounts of data; it is also unaffected by external interference (electromagnetic interference, temperature variations, etc.). While fiber optics certainly offers the advantage of fast, high-quality and secure data transmission, its high installation cost is a drawback for network builders.
