LEDs and VCSELs are used for data transmission in optical fibers. They are less expensive than laser diodes. Equipped with a fiber connection, they can be easily integrated into a system.
Fiber-coupled LEDs and VCSELs for fiber optical data transmission as well as for measurement devices and optical sensors.
