A fiber optic data link consists of three parts – transmitter, optical fiber, and receiver. Is an illustration of a fiber optic data-link connection? The transmitter, optical fiber, and receiver perform the basic functions of the fiber optic data link.

Each part of the data link is responsible for the successful transfer of the data signal. A fiber optic data link needs a transmitter that can effectively convert an electrical input signal to an optical signal and launch the data-containing light down the optical fiber. A fiber optic data link also needs a receiver that can effectively transform this optical signal back into its original form.

This means that the electrical signal provided as data output should exactly match the electrical signal provided as data input. The transmitter converts the input signal to an optical signal suitable for transmission. The transmitter consists of two parts, an interface circuit and a source drive circuit. The transmitter’s drive circuit converts the electrical signals to an optical signal. It does this by varying the current flow through the light source.

The two types of optical sources are light-emitting diodes (LEDs) and laser diodes. The optical source launches the optical signal into the fiber. The optical signal will become progressively weakened and distorted because of scattering, absorption, and dispersion mechanisms in the fiber waveguides.
