An optical receiver is the endpoint device in a fiber optic link that translates pulses of light into electrical signals that electronic equipment can process . The process begins with a photodetector, which captures the light emerging from the fiber and generates a small electrical current proportional to the light's intensity. This weak signal is then amplified by a front-end amplifier, filtered to remove noise, equalized to correct pulse distortion, and sampled to determine digital ones and zeros. Optical receivers are essential for all fiber optic networks, from undersea cables to data center interconnects .
Optical networking uses light to transmit data through fiber optic cables, offering much higher bandwidth and lower latency than traditional copper networks . Data is converted from electrical signals to optical signals at the transmitter, sent through the fiber, and then converted back to electrical signals by the optical receiver . Networks can be classified by scale:
Modern optical networks often employ Wavelength Division Multiplexing (WDM), particularly Dense WDM (DWDM), which allows multiple data streams to travel simultaneously over a single fiber, each on a different wavelength . Optical networks can also include optical wireless systems, which use infrared or light waves for short- or long-range communication, requiring line-of-sight connections between transmitters and receivers . These systems complement RF-based networks and provide high security, immunity to interference, and high data rates.
