Description
Optical fiber is a glass thread surrounded by a reflective sheath. Its main property is to act as a conduit through which light can circulate. It is used to transport digital information. It is a cable designed for transmitting information at high speeds over long distances. Unlike traditional copper cables, which use electrical signals, optical fiber uses light to carry data. Due to its ability to carry large amounts of data and its resistance to interference, it is widely used in telecommunications networks and plays a key role in modern connectivity.
Types of possible networks:
- FttH (Fiber to the Home): This type of network is characterized by a connection that goes directly to the subscriber's home, meaning the fiber termination is inside the building.
- FttLa (Fiber to the Last Amplifier): Also called coaxial fiber, the cable stops at the last amplifier, and the link between the amplifier and the subscriber is made using a coaxial cable.
- FttB (Fiber to the Building): Similar to coaxial fiber, but it involves running the optical fiber to the base of the building.
- FttO (Fiber to the Office): Designed for businesses, it is popular among companies because it does not rely on a shared network like FttH and ensures very high-speed connectivity.
Types of fiber:
- Multimode Fiber: The first type used, easy to install but with limited bandwidth. It is reserved for short distances.
- Single-mode Fiber: Has virtually infinite bandwidth (in theory), making it the solution for long distances (> 5 km).
Optical fibers used in communication networks are available in various diameters. These different fiber diameters offer specific characteristics that make them suitable for various applications.
- OS1/OS2 – Single-mode fiber for building links (unlimited bandwidth).
- OM1 – Multimode fiber for video and network connections (100Mb/s).
- OM2 – Multimode fiber for video and network connections, with higher bandwidth (100Mb/s & 1Gb/s).
- OM3 – Multimode fiber for Gigabit and data center connections (10Gb/s).
- OM4 – Multimode fiber for data centers (10Gb/s & 40Gb/s).
