What does PD mean in optical modules
A photodiode is a semiconductor device that converts light into electrical current. OS stands for “oculus sinister,” your left eye. The. Photodiodes operate by absorption of photons or charged particles and generate a flow of current in an external circuit, proportional to the incident power. Photodiodes can be used to detect the presence or absence of minute quantities of light and can be calibrated for extremely accurate. Optical module usually consists of a transmitter assembly (TOSA, containing a laser LD chip), a receiver assembly (ROSA, containing a photodetector PD chip), a driver circuit, an optoelectronic interface, a heat sink (some models), a housing, a pull ring and so on. These devices are currently used in the fields of telecommunications and medicine and in industrial cutting and welding applications.
