  • What is the function of an optical port module

    What is the function of an optical port module

    An optical module is a small device that moves data using light. It changes electrical signals into light signals and back again. This helps data travel faster and farther than with copper cables. These modules typically consist of a transmitter, which converts electrical signals into a light signal, and a receiver, which converts the received signal back. The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. Operating at the physical layer of the OSI model, optical modules are core devices in optical. The optical module, known as Optical Transceiver in English, is a general term for various module categories, including optical receiver modules, optical transmitter modules, optical transceiver modules, and optical forwarding modules.
