An optical receiver converts light pulses in fiber optic networks into electrical signals that can be read by electronic devices. The receiver uses a photodiode to amplify the signal and translate it into a binary code. Different photodiode materials have varying energy level ranges. Optical transmitters and transceivers are used to transform electrical information into light and vice versa.
An optical receiver, sometimes called a fiber optic receiver, is a component in a fiber optic network. The role of the receiver is to translate the light pulses sent through the optical fibers into electrical signals. Once the information is converted into electricity, the information can be read by an electronic device, such as a computer, connected to the network.
An optical receiver is an important component in a fiber optic network. In optical fibers, light is used to send information between electronic devices, such as two computers on a network. The wires, which are usually made of a highly reflective silica glass, are used to transmit pulses of light. The light bounces along the hollow silica tube until it reaches the optical receiver at the other end.
The information sent along the fiber optic cable is in the form of pulses of light. These pulses are translated into electrical information by the optical receiver. This device translates light pulses into a series of ones and zeros, called a binary code. Computers can then translate these long strands of tracks into the processes seen on computer monitors.
The light pulses travel through fiber optic cables until they reach the photodiode on an optical receiver. A photodiode is made of a material that can lose electrons when hit by a photon moving at a certain wavelength. When the photodiode is struck by light energy, electrons are released. These electrons create very small electric charges which the optical receiver then has to amplify. Once the signal has been amplified, it can be translated into electrical information in the form of a stream of digital ones and zeros.
Optical pulses sent through a fiber optic cable can vary greatly in their energy levels. The material from which a photodiode is made determines what range of energy levels it can translate into electricity. Silicon photodiodes, for example, can receive information traveling between 190 and 1,100 wavelengths of the electromagnetic spectrum (nm). Lead sulfide can only receive information from photons with enough energy to travel between 1,000 and 3,500 nm.
Optical receivers can only transform optical information into electrical information. A similar device, called an optical transmitter, is used to transform electrical information into light. There is also a device called an optical transceiver that can receive and transmit optical and electrical information, translating freely between the two.
