Fiber optic transceiver installation difficulty

Fiber optic transceivers are relatively simple network hardware devices with fewer interfaces than switches, so their wiring and connection are relatively simple. They can be used alone or installed on a rack. Network switches can be used alone in home networks or small offices, or installed on racks in large data center networking. Generally, the module needs to be plugged into the corresponding port, and then connected to the computer or other network equipment with the corresponding network cable or fiber optic jumper
