The optical module used in conjunction with a multi-mode fiber can obtain the best transmission characteristics. This optical module is called a multi-mode optical module. It can transmit multiple modes of light. The appearance is shown in the figure below. Multi-mode optical modules are generally used for short-range transmission because they have a large dispersion between modes and limit the frequency of transmission of digital signals.
