Fiber Optic Communication
Ethernet standards that support communication over optical fiber, transmitting data by sending light signals, enabling long-distance communication without copper cabling.
Advantages of Fiber Optic
No radio frequencies are involved, making the communication more secure and unaffected by nearby radio frequencies, ideal for environments with high RF interference.
Fiber Optic Components
The core of the fiber optic cable is where light travels, surrounded by cladding with a low reflective index, and protected by a buffer coating.
Ferrule
A large ceramic protector around the fiber optics, with the core fiber inside, used in fiber optic connections.
Multi-mode Fiber
Used for short-range communication (up to 2 km), typically with an LED light source, allowing multiple reflections of light through the fiber.
Single-mode Fiber
Used for long-distance communication (up to 100 km), typically with a laser light source, with a narrower core allowing a single mode of light transmission.
