Fiber Optics - Transmitters - Discrete

Fiber optic transmitters are indispensable optoelectronics typically used to convert electrical signals into optical signals. They employ laser or light-emitted diode LEDs as their optical source and are built for use with either single-mode or multi-mode fiber. These transmitters can turn modulated light on or off or linearly vary the light's intensity between two predetermined levels. They are composed of an interface circuit, a source drive circuit, and an optical source, each performing a specific function, such as; the interface circuit obtains electrical signals, the source drive circuits convert these signals and activate the LED or laser diode and then transmit the light signals to the fibre optic cable.   

How Do Fiber Optic Transmitters Operate?

Fiber optical transmission begins with an electrical signal that carries data to be transmitted. The signal can be digital (computer) data or analogue (audio/video) data. The transmitter features a light source, typically an LED or laser diode, which is a pathway for the data to be transmitted in the form of light. 

What are the Cable Types for Fiber Optics - Transmitters - Discrete?

Discrete fiber optic transmitters are created to be used with various cable types, such as:

• Single-mode Fiber Optics: These cable features have tiny cores and can be used with laser sources for high-speed and long-distance connections. 
•  Multimode Fiber Optics generally have larger cores than single-mode fibers and are primarily used with LEDs for lower speed and shorter distance connections.
