How to use a switch with an optical module
This video shows you how to properly use the optical transceiver module on the switch, including how to insert the module into the equipment and how to pull the module out. moreOptical switching represents a fundamental technological evolution, shifting data routing from the domain of electrons to the realm of photons, or light. Using the wrong module can result in link failures, reduced performance, or complete incompatibility. When an object is moved into the slot between the LED and phototransistor the light is interrupted and the phototransistor switches off. Among the many optical modules, SFP+ modules are one of the most. Anti-static measures must be taken when using optical modules, whether indoors or outdoors, and you must ensure that you touch the optical modules with your hands while wearing anti-static gloves or anti-static bracelets. It is strictly forbidden to touch the golden finger of the optical module.
