Optical fiber: what it is, how it works and why it changes your connection

Optical fiber transmits data using light pulses inside very thin glass or plastic fibers. It supports streaming, smart working, cloud services, backups and business applications.

FTTH and FTTC

FTTH means Fiber To The Home: fiber reaches the home or office. FTTC means Fiber To The Cabinet: fiber reaches the street cabinet and the last part uses copper. This difference affects speed, stability and performance.

Not only download

Upload, latency and stability matter too. Upload is important for cloud, file sending and video calls. Low latency makes the connection feel more responsive.
