Study Notes
Acceptance Angle and Numerical Aperture
- The acceptance angle refers to the maximum angle at which light can enter the fiber core while still being able to propagate through it.
- Numerical Aperture (NA) is defined as the sine of the largest angle for total internal reflection of an incident ray in the core.
Information Source
- The information source provides the initial electrical signals that are to be transmitted via optical fiber to a destination.
Electrical Transmitter
- The electrical transmitter is integral to the communication system, converting information signals into electrical signals.
Optical Source
- The optical source is responsible for converting electrical signals into optical signals.
- Common optical sources include Light Emitting Diodes (LEDs) and lasers.
Optical Fiber
- Optical fibers serve as waveguides, transmitting optical pulses using the principle of total internal reflection.
- Made of glass, fibers act as channels between the transmitter and receiver.
Optical Detector
- The optical detector's function is to detect incoming optical signals and convert them into proportional electrical signals.
Electrical Receiver
- The electrical receiver transforms the electrical signals from the signal processor into sound waves or visual images.
- These signals become directly usable when connected to computers or other machines through the fiber system.
