Study Notes
Optical Fiber Communication
- Optical fiber is associated with data transmission using light pulses traveling through a long fiber made of plastic or glass.
- Metal wires are not preferred for transmission in optical fiber communication as signals travel with more damage.
- A fiber optic cable can contain any number of glass fibers, ranging from a few to a couple hundred.
Types of Fiber
- There are two main types of fiber, each with different applications.
- Multimode fiber has a large core, allowing for multiple paths through the fiber.
- Single-mode fiber has a much smaller core, allowing for only one path.
