What is an integrated optical module
As an important part of fiber-optic communication, an optical module is a photoelectric converter which converts electrical signals into optical signals and vice versa. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. 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. An. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. indie's Integrated Optical Modules combine EXALOS high-performance SLEDs and Laser Diodes using micro-optical and free-space technologies, offering customizable solutions for advanced optical applications.
