Fibre optic receivers convert data from fibre optical cables into electrical signals. Receivers accept the data and then transform the signals into electrical pulses.
The receivers contain semiconductors called photodetectors and an amplifier to produce what is called logic compatible output. This means that the signal output is not controlling the circuit status (current flow).
Some fibre optic receivers perform both the receiving and transmission functions and are referred to as transceivers.
Fibre optic receivers are used in many applications like sensoring systems, machine safety systems and tower lights.
These receivers are also useful in solving high voltage isolation issues like signal interference, where large data quantities must be transferred over long distances.
Fibre optic receivers also help to identify transmission errors in loopback testing activities for systems, process equipment and machinery.
Two main types of fibre optic receivers exist:
