When you apply voltage across this junction, electrons and holes recombine, and each recombination releases a photon (a particle of light). This is exactly what happens inside an LED. What makes a laser diode different is a pair of reflective surfaces built into the chip that form. A laser diode is a small semiconductor chip that converts electrical current directly into a focused beam of light.

There are various connection solutions available for switching networks, such as optical modules + optical fibers, Active Optical Cables (AOC), and Direct Attach Cables (DAC). DAC can be further categorized into active ACC, AEC, and passive DAC. But what. AOC is an active optical cable. The AOC consists of two modules on both ends, with a section of fiber optic connection in the middle. The optical module and the optical cable are integrated, and the optical modules at both ends require laser components; AOC eliminates the possibility of optical.
