Advantages and Disadvantages of Optical Modules
The optical module is an essential component in optical communication systems that enables the transmission and reception of data over optical fibers. It consists of various components, including a transmitter, receiver, and electronic circuitry, all integrated into a compact package. The transmitter converts electrical signals into optical signals, which are then transmitted over the fiber. On the other end, the receiver receives the optical signals and converts them back into electrical signals for further processing.
One of the main advantages of optical modules is their high data transmission capacity.
